Question

what is earth and explain in 20 sentence

Answer 1

The large mass of the Sun makes Earth move around it, just as the mass of Earth makes the moon move around it. Earth also turns around in space, so that different parts face the Sun at different times. Earth goes around the Sun once (one year) for every 3651⁄4 times it turns around (one day).

Earth is the only planet in the Solar System that has a large amount of liquid water.[30] About 74% of the surface of Earth is covered by liquid or frozen water. Because of this, people sometimes call it the blue planet.[31]

Because of its water, Earth is home to millions of species of plants and animals which require water to survive[32][33] The things that live on Earth have changed its surface greatly. For example, early cyanobacteria changed the air and gave it oxygen. The living part of Earth's surface is called the "biosphere".[34]

What is Earth ?

• The Earth is an oasis of life in the universe. The temperature, the weather and many other factors contribute to sustain life on earth.

• The temperature at the earth's centre or the core may be as a high 7000°C, hotter than the surface of the Sun.

• The Earth is 4.5 to 4.6 billion years old, but the oldest known rocks are less than 4 billion years old.

How the earth formation ?

• Earth is cooling now but very, very slowly, because it makes heat in its interior. Earth is thought to have arisen from a cloud of gas and dust in space. Solid particles, called 'planetesimals' condensed out of the cloud, just like the rain.

• They are thought to have stuck together and created the earth early. Bombarding planetesimals heated earth to a molten state.So, earth started out with a lot of heat.

• While the heat energy produced inside Earth is enormous, it is some 5,000 times less powerful than what earth receives from the Sun. The sun's heat drives the weather and ultimately causes erosion of use mountains to tiny rocks and sand.
