Jet Streams Jet streams are narrow and meandered strip of fast blowing air currents found in the upper altitude (i.e. upper troposphere or lower stratosphere). El
Air in motion is known as wind. Wind plays a significant role in determining the weather system of a given region. Because of the rotation
The composition of the Earth’s atmosphere changes with altitude. The major constituents of the Earth’s atmosphere are − Nitrogen – 78.09% Oxygen – 20.95% Argon
The Earth’s rotation on its axis causes day and night. The Earth’s revolution (in its orbit around the Sun) causes change in seasons. When nights

Asteroid and comet are celestial bodies that are formed around 4.5 billion years ago when the solar system was formed. Although both orbit the Sun,
Dams are the structures which are created to hold back the flowing water of rivers. And store the water for future uses. Which would have
There are 13 Major Sea Ports in India and about 200 small sea parts are located all around the coast of India.All this ports are
It is generally assumed that planets are formed by the accretion of gas and dust in a cosmic cloud, but there is no way of
Scientists believe that the Earth’s outer crust is made up of about huge fragments, called tectonic plates, that fit together like a cracked eggshell. According
The moisture gathered in clouds eventually falls to the ground as liquid rain or drizzle, or as solid, frozen SNOW or HAIL. Any kind of falling moisture is
Air always contains some water vapour from oceans, lakes, and the ground. Clouds form when the air cools below a certain temperature, so that some
Wind is the movement of the atmosphere. The atmosphere moves because the Sun heats the Earth’s surface, causing air to increase in temperature, expand, and
The weather is the day-to-day condition of the atmosphere at a particular place and time – whether the air is warm or cool, moist or
Every part of Earth has its own climate – the typical pattern of weather over a long period of time. An area’s climate is affected
The Earth would be as lifeless as the Moon without the atmosphere – a blanket of gases surrounding the planet and extending about 700 km
Lakes form where water fills hollows in the landscape. Some of these hollows are formed by glaciers gouging into the ground, and some are created
Islands are land masses entirely surrounded by water. They are found in oceans, seas, rivers, and lakes. Islands vary in size from tiny rock outcrops
Just a century ago, the ocean floor was largely unknown. Now we know that the deep oceans have features such as mountains, deep valleys, and
About 71 per cent of our planet’s surface is covered by oceans and seas. In order of size, the five great oceans are the Pacific,
Coasts, which form the boundary between land and ocean, receive a constant battering from the wind and waves. In calm weather, the water merely laps
About one-tenth of Earth’s dry land and one-eighth of its oceans are covered with ice. This ice is made of snow that collects and becomes
The rocky material that is transported and DEPOSITED by rivers, seas, glaciers, and the wind is called sediment. Clay, sand, and gravel are all types of sediment.
Much of the solid bedrock of the Earth’s crust is covered in soil. This loose, soft material is a mixture of organic matter and particles
The process that breaks up and carries away the rocks and soils that make up the Earth’s surface is called erosion. It is caused by
Geologists (scientists who study rocks) divide the time since the Earth was formed until today into chunks called periods. During the various periods, different species
Fossils are the remains or traces of an animal or plant that are preserved in rock. They come in many forms, from footprints and faint
The Earth is covered in a layer of solid rock called the crust. Rocks are either SEDIMENTARY , IGNEOUS, or METAMORPHIC. Almost all rocks made of minerals, but
Minerals are the materials that make up the rocks of the Earth’s crust. Among thousands of different minerals, only a few, including quartz, feldspar, and
New mountains are built when rocks are pushed upwards by the movement of the giant rocky plates that make up the Earth’s crust. The rocks
Volcanoes are vents (openings) in the ground from which magma (molten rock), ash, gas, and rock fragments surge upwards, in an event called an eruption.
Earthquakes are caused by movements of the giant tectonic plates that form Earth’s crust. SEISMOLOGY is the study of earthquakes. Most occur at cracks called FAULTS, at the
Scientists believe that the Earth’s outer crust is made up of about huge fragments, called tectonic plates, that fit together like a cracked eggshell. According
The Earth is a giant, spinning ball of rock and metal. The rocky surface we live on is the Earth’s thin outer layer, called the
