volcano

A volcano is an opening in Earth’s crust. When a volcano erupts, hot gases and melted rock from deep within Earth find their way up to the surface. This material may flow slowly out of a fissure, or , in the ground, or it may explode suddenly into the air. Volcanic eruptions may be very destructive. But they also create new landforms. There are more than 1,500 potentially active volcanoes in the world today.

 

During a volcanic eruption, hot melted rock called magma escapes from a vent, or opening, in Earth’s surface, or crust. Magma released from a volcano is known as lava. Fresh lava ranges from 1,300 to 2,200 °F (700 to 1,200 ° C) in temperature. It glows red as it flows out of the volcano’s opening. As it cools, it hardens into rock.

Strong volcanic eruptions throw bits of magma into the air.

Earth’s crust is made up of huge, rocky pieces called plates. The plates move slowly over the crust. Most volcanoes lie along the boundaries between these plates.

Some of the most violent eruptions take place where the edge of one plate is forced beneath the edge of another. This forces magma to rise to the surface. Hot gases in the magma make these volcanoes very explosive.

Volcanic eruptions create new landforms that are also called volcanoes. The two most common types are stratovolcanoes and shield volcanoes.

Stratovolcanoes, also called composite volcanoes, are mountains shaped like cones. They have a narrow top with steep sides and a wide bottom. A crater, or bowl-shaped pit, usually lies at the top. Stratovolcanoes are made up of layers of hardened lava and ash. Thousands of eruptions left these layers over millions of years. 

Hot springs, geysers, and fumaroles are other types of volcanic activity. They happen in places where magma heats underground water. A hot spring is a place where warm water comes up through the ground. A geyser is a kind of hot spring that shoots water and steam into the air. Fumaroles are vents that release gas and steam.

Volcanology is the branch of geology that focuses on volcanoes. Many volcanologists work in observatories, from which they keep track of earth tremors and other signs of volcanic activity. Others venture forth to the slopes and craters for an even closer look. On the basis of what they measure and see, they try to predict when an eruption might take place, how severe it will be, and which places will be in the danger zone.

The effects of volcanoes are not entirely harmful. Volcanic ash soil—called andisol—is good for growing crops. In addition, the volcanic glass called obsidian has been used by many of the world’s peoples for weapons, tools, and ornaments. People also use the volcanic stone called pumice for cleaning wood, metal, and other surfaces and in producing building materials.

The heat within Earth that is released in volcanoes is an enormous potential source of energy.

The word volcano comes from the name of Vulcan, the ancient Roman god of fire and metalworking. The Romans believed that volcanic eruptions resulted when Vulcan made thunderbolts and weapons for the gods. Other cultures explained volcanoes as outbursts of anger from a god or goddess. Pele was the name of the volcano goddess of the native Hawaiians.

Volcanoes have a long history of destruction. In ad 79 the eruption of Mount Vesuvius destroyed the whole city on pompeii.

Lava is hot, liquefied rock that flows from a volcano or other opening in the surface of Earth. When the liquid rock is still underground it is known as magma. Igneous rock is formed when lava cools and hardens.

A mountain is a landform that rises high above its surroundings. Taller than a hill, it usually has steep slopes and a rounded or sharp peak. Mountains are rarely found alone. Groups of mountains are called ranges. Lines of ranges form mountain belts.

Geology is the study of the physical features and history of Earth. Scientists who work in geology are called geologists.

Geology is an important science for many reasons. It answers questions about how Earth came to have its present shape and form. It is useful for finding important materials in Earth’s crust, such as oil. Geology is also helpful for predicting earthquakes and other natural hazards.

In an earthquake, huge masses of rock move beneath the Earth’s surface and cause the ground to shake. Earthquakes occur constantly around the world. Often they are too small for people to feel at all. Sometimes, however, earthquakes cause great losses of life and property.

Energy is another word for power. Energy makes things move. It makes machines work. Energy also makes living things grow.

Mount Vesuvius is an active volcano in southern Italy. It is famous for an eruption that happened in ad 79. Thousands of people died when lava, ashes, and mud buried the cities of Pompeii, Herculaneum, and Stabiae. The cities were forgotten until archaeologists began digging up their ruins in the 1700s.

Mount Vesuvius stands about 4,200 feet (1,280 meters) high, but its height changes after each major eruption.

Fire drill

         

Fire drill              

Fire drill is a special practice in case of fire. It is mainly done in schools and offices. In this they mostly give us safe rules to protect us from fire. These are-

1] In schools it is mostly important to save ourselves instead of our property

2]If fire is there, instead of searching of a fire brigade we need to call a fire brigade dialing number ‘ 101 ‘ as the fire increases if not it off

There are some people that come and explain these points. The safest point they tell us for lives is to help the injured people . The people working help us to fire.

The people of U.S.A have a training to keep a wet cloth to cover nose  and lay down at the ground as most people die due to smoke a s they cant breathe .

Aliens AND Ufo

HELLO FRIENDS.NICE TO MEET YOU ONCE AGAIN.WELCOME BACK TO WORLD OF INFORMATION. AS USAUL IF YOU LIKE IT THEN COMMENT IT. TODAY MY TOPIC IS SOMETHING THAT IS SAID TO BE IN OTHER PLANETS EXCEPT EARTH.YES ,YOU ARE RIGHT ,ALIENS AND UFO.

UFO (UNIDENTIFIED FLYING OBJECTS

INTRODUCTION

We all think that ALIENS travel around space in spaceships. We have given the spaceships the name UFO meaning Unidentified Flying Object.

Many UFOs are sighted at many different places. Many of them are sighted in India too.

 

Many believe that UFOs come near unlucky people and show a light which pulls the people to their UFO.

An unidentified flying object, or UFO, is anything in the sky that cannot be explained by the person who sees it. Some people think that UFOs are alien spaceships. But most scientists say that UFOs can be explained in much more ordinary ways.

Descriptions of UFOs have ranged from glowing wheels to colored balls of light to cigar-, crescent-, or disk-shaped objects. 

FACTS ABOUT UFO:

  • UFO stands for “Unidentified Flying Object”.
  • There have been many claims of UFO sightings since the 1940’s.
  • Some say a UFO sightings occur somewhere on the planet every three minutes.
  • In 1991, a Roper poll was conducted. The poll said that 4 million people believe they have been abducted by aliens.
  • In 1996 a Gallup poll was conducted which said that 71% of Americans believe that the government knows more about UFOs than there are telling the people.
  • The first documented UFO sighting is in the Bible. The prophet Ezekiel described a “great cloud with fire enfolding itself, a wheel in the middle of a wheel that descended and fired lightning bolts into the earth.“
  • Winston Churchill reported a strange airship in Kent, England, Oct. 14, 1912. It was the first case of a UFO being “officially” reported.
  • The first photograph of a UFO was taken in 1883 by astronomer Jose Bonilla in Zacatecas, Mexico.
  • UFOs were often seen and photographed during NASA’s space missions in the 1960s.
  • Probably the biggest UFO mystery has to do with The Roswell incident. was the recovery of debris from an object which crashed near Roswell, New Mexico, in June or July.

      

ALIENS

INTRUDUCTION

The word alien is a popular word for an extraterrestrial life-form, or a being from another planet. No one knows whether there is life elsewhere in the universe. But some scientists think that it is possible. (On Earth, “aliens” is also a word for people who are not citizens of the country in which they live.)

POPULAR IDEAS ABOUT ALIENS

Whether life exists on other planets or not, the idea of aliens has excited people for years. Lots of people enjoy science fiction stories about aliens—also called extraterrestrials, or ETs. Some believe that aliens actually have visited Earth. Many people have reported seeing unusual objects in the sky. Some think that these unidentified flying objects, or UFOs, are alien spaceships. The presence of aliens on Earth has never been proven, however.

THE SEARCH OF ALIEN LIFE

Most scientists believe that for another planet to have life on it, it must be similar to Earth in several ways. It is likely to need an atmosphere (air) and water. It also must orbit a star, like the Sun, at a good distance. This star would provide the right amount of light and heat for life to exist.

Did You Know?
The word extraterrestrial means “beyond Earth.”

Solar System

HELLO FRIENDS ,MY NAME IS ANSH FROM OIST(ORCHID THE INTERNATIONAL SCHOOL THANE) 5 D .

WELCOME TO THE WORLD OF INFORMATION.

TODAY YOU ARE GOING TO LEARN ABOUT OUR SOLAR SYSTEM.

SO LETS BEGAN:

The solar system consists of the sun and everything that orbits, or travels around, the sun. This includes the eight planets and their moons, dwarf planets, and countless asteroids, comets, and other small, icy objects. However, even with all these things, most of the solar system is empty space.

The solar system itself is only a small part of a huge system of stars and other objects called the Milky Way galaxy.

 

At the center of the solar system is a star called the sun. It is the largest object in the solar system. Its diameter, or distance through its center, is 865,000 miles (1,392,000 kilometers). In addition, the sun contains more than 99 percent of all the material in the solar system. The sun is a very hot ball of hydrogen and helium gases. It has a temperature, at its core, of more than 28,080,000° F.

The gases that surround the sun shoot out a stream of tiny particles called the solar wind. It flows outward through the whole solar system. The solar wind is what causes auroras, or displays of colored light in the night sky in parts of Earth. In the Northern Hemisphere these auroras are called the northern lights.

After the sun, the largest objects in the solar system are the planets. In order from closest to the sun, these planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Most of them orbit the sun in paths shaped like circles. Most of the planets have at least one moon. However, they vary widely in size, temperature, and makeup.

Scientists used to call Pluto the ninth planet. But in 2006 scientists decided that Pluto is a dwarf planet.

Millions of small chunks of metal and rock called asteroids also orbit the sun. Most asteroids are found in a ring between Mars and Jupiter. They are believed to be debris, or bits of material, left over from collisions between other bodies in the solar system. The largest asteroids are hundreds of miles in diameter, but most are much smaller. Small asteroids regularly fall to Earth or burn up in the sky.

Comets are small chunks of dirt and ice. Billions of them orbit the sun in very long paths shaped like ovals. When they are closest to the sun, the sun’s radiation causes them to glow. Most comets are too small or too distant ever to be seen from Earth. Comets come from two parts of the outer solar system: the Kuiper Belt and the Oort Cloud.

Beyond Neptune lies the Kuiper Belt, a flat ring of millions of small, icy objects. These objects orbit the sun at a very great distance. They are mostly 30 to 50 times farther from the sun than Earth is.

At the outer reaches of the solar system is the Oort Cloud. It is a huge cloud of countless small, icy objects. The Oort Cloud surrounds the rest of the solar system.

The solar system was formed about 4.7 billion years ago. It probably started as a loose cloud of gas and dust. Scientists think that a force called gravity pulled parts of the cloud together into clumps. The largest clump was squeezed together so tightly that it got very hot. This clump eventually became the sun. Over millions of years the other clumps became the planets. 

In 1957, the Soviet satellite Sputnik 1 became the first man-made object to orbit Earth. Since then, scientists have sent many spacecraft to explore various parts of the solar system. Spacecraft have carried astronauts into orbit around Earth, to the moon, and to man-made space stations. Other spacecraft, called probes, have carried cameras and scientific equipment but no astronauts. Space probes have landed on the planets Mars and Venus, on asteroids, and on Titan.

The solar system is also known as a planetary system. Since the 1990 s scientists have found many planetary systems beyond our solar system. In these systems, one or more planets orbit a star—just as the eight planets in our solar system orbit the sun. These planets are called extra solar planets. Finding other planetary systems is not easy, however, because extra solar planets appear much dimmer than the stars they orbit. 

 

Cats

HELLO FRIENDS ,MY NAME IS ANSH FROM OIST(ORCHID THE INTERNATIONAL SCHOOL THANE) 5 D .

WELCOME TO THE WORLD OF INFORMATION.

TODAY YOU ARE GOING TO LEARN ABOUT CATS

SO LETS BEGAN:

The domestic cat, or house cat, is a small mammal that has lived among people for thousands of years. People have kept cats as pets, used them as hunters, and even worshiped them as gods. Domestic cats belong to the same animal family as the lion, tiger, jaguar, leopard, puma, and cheetah. The scientific name of the domestic cat is Felis catus.

Domestic cats live with people in nearly every part of the world. Some domestic cats have no home. These cats, called feral cats, wander freely in many cities.

The domestic cat has a long and powerfully built body. Males are about 28 inches (71 centimeters) long. Females are about 20 inches (51 centimeters) long. Large eyes help the cat to see well at night. Its triangular ears can turn quickly toward the source of a sound. Four rows of stiff whiskers grow on each side of the nose. These give the cat a delicate sense of touch.

Domestic cats are carnivores, or meat-eaters. Many hunt and eat small animals, including birds, mice, and rabbits. They use their claws, which they can draw back or in, and their strong, sharp teeth to catch prey. House cats eat mainly canned or dry food made especially for cats.

 

A female cat gives birth to a litter of kittens about two months after mating. A female may have two to three litters a year. The average litter is four kittens, but there may be only one kitten or as many as seven. A newborn kitten is about 3 inches (8 centimeters) long. It has no teeth, the ears lie flat, and the eyes are closed. A kitten’s full development takes about one year. …

The cat is the only animal that makes a sound called a purr.

About 4,500 years ago the ancient Egyptians worshiped cats. The Egyptians probably domesticated, or tamed, wild cats about 3,500 years ago. They used these cats to the rats and mice that ate their stored grain.

During the Middle Ages (about ad 500–1500), many Europeans feared cats because cats were linked with witches. Some people still think that black cats are unlucky.

Today millions of people around the world keep cats as pets.

Robots

HELLO FRIENDS ,MY NAME IS ANSH FROM OIST(ORCHID THE INTERNATIONAL SCHOOL THANE) 5 D .

WELCOME TO THE WORLD OF INFORMATION.

TODAY YOU ARE GOING TO LEARN ABOUT robots

SO LETS BEGAN:

A robot is a machine that does tasks without the help of a person. Many people think of robots as machines that look and act like people. Most robots, though, do not look like people. And robots do only what a person has built them to do.

Most robots are computer-controlled devices with many parts. An industrial robot, for example, is an arm like machine that can turn at several joints. It has a hand like part to grasp and hold things. Motors move the parts.

Some robots can be “taught” to do a job. For example, a person might guide an industrial robot through the movements needed to do something. Sensors on the robot send signals about the movements to the computer.

Most industrial robots are used in factories. Some robots load, move, and unload materials. Others are used on assembly lines to help build things such as cars and appliances.

Robots are especially useful because they can do things that could be dangerous for people. For example, they can be sent deep underwater or into space. Robots can also handle dangerous materials such as radioactive waste or harmful chemicals.

Writings from ancient Greece and China tell of toys called automatons, which were like robots. They were set in motion by steam, air, water, or falling weights. In the late 1700s and early 1800s complex automatons could play music or write with a pen on paper. During this time people also built machines to help do certain kinds of work. Modern robots only came about after computers were invented. With computers, people could program robots…

Humanoid robot

HELLO FRIENDS ,MY NAME IS ANSH FROM OIST(ORCHID THE INTERNATIONAL SCHOOL THANE) 5 D .

WELCOME TO THE WORLD OF INFORMATION.

TODAY YOU ARE GOING TO LEARN ABOUT A humanoid robot

SO LETS BEGAN:

A humanoid robot is a robot with its body shape built to resemble the human body. The design may be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of  locomotion, or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robots also have heads designed to replicate human facial features such as eyes and mouths. Androids are humanoid robots built to aesthetically resemble humans.

 

Giraffe

HELLO FRIENDS ,MY NAME IS ANSH FROM OIST(ORCHID THE INTERNATIONAL SCHOOL THANE) 5 D .

WELCOME TO THE WORLD OF INFORMATION.

TODAY YOU ARE GOING TO LEARN ABOUT GIRAFFES

SO LETS BEGAN:

Giraffes are the tallest animals on earth. Male giraffes can grow to a height of about 17 feet.

If you lived in a two-story house an adult giraffe could look into
your bedroom window on the second floor.

Giraffes only live on the continent of
Africa. The only giraffes in the United States are found in zoos or animal parks.
Visitors love to see the giraffes because they are so tall. Besides standing on long legs, giraffes have the longest neck of any animal.
 The neck of a giraffe can be eight feet long. Giraffes love to eat leaves. With their great height, giraffes easily
eat leaves from the tops of acacia trees.
Giraffes get enough food because no other animals can reach the same food that giraffes like. Giraffes spend most of their time eating. Giraffes don‟t sleep much.
They just take short naps while standing up. Giraffes don‟t drink much water. They get most of the water they need from the leaves they eat. It is very hard for an adult giraffe to get a drink of water from a stream or pool. Giraffes are beautiful animals.
They have an unusual coat that has large brown spots on a cream background. There are many different kinds of giraffes across Africa.
Each kind of giraffe has a slightly different shape to their spots. A giraffe‟s coat pattern helps it to blend in with the landscape in which they live.. .

WELCOME TO THE WORLD OF INFORMATION.

TODAY YOU ARE GOING TO LEARN ABOUT parents

SO LETS BEGAN:

As god can not come everywhere he gave us parents.

What are parents?

Parents are caretakers which give birth to us,rise up lovingly and love us very much. They fulfill our every need.they can do anything for us.

Role of parents:

 Parents are the child’s first role model. Parents play important   role in encouraging and motivating their kids to learn. Good parental support helps child to be positive, healthy and good life long learner.
A parent must serve a child’s emotional and physical needs and protect the child from abuse from the other parent or another household member. Additionally,parents must meet their children’s basic needs for food, clothing, housing, medical care, and education.
quotes about parents 
  • Parental love is the only love that is truly selfless, unconditional and forgiving. We never know the love of a parent till we become parents ourselves. 
  • Parents were the only ones obligated to love you; from the rest of the world you had to earn it.
  • One of the greatest titles in the world is parent, and one of the biggest blessings in the world is to have parents to call mom and dad.
So we should always listen ,respect, and love our parents.
