Hi friend,
---------------------------------------------------
Earth is the spherical planet we live on. It is the third planet from the sun. It is the only planet known to have life on it. Earth formed around 4.5 billion years ago. It is one of four rocky planets on the inside of the Solar System. The other three are Mercury, Venus and Mars.
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 365¼ times it turns all the way around (one "day").
Earth is the only planet in our solar system that has a large amount of liquid water. About 71% of the surface of Earth is covered by oceans. Because of this, people some times called it "blue planet".
Because of its water, Earth is home to millions of species of plants and animals.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".

➡With erupting volcanoes and a constantly moving crust, the Earth is changing even today.
➡The solar system was formed from a cloud of gas and the wreckage of a supernova explosion which in result lead to the formation of Earth.
➡Meteorite collisions, radioactive decay and planetary compression made Earth become hotter and hotter. After a few hundred million years the temperature of Earth reached 2,000C - the melting point of iron - and Earth's core was formed.
➡about 4bn years ago - the product of multiple volcanic burps. Alternatively, they may have come from comets colliding with Earth and releasing water and gases at the surface.
➡The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon.
➡Geological change has been a constant of Earth's crust since the time of its formation, and biological change since the first appearance of life. Species continue to evolve, taking on new forms, splitting into daughter species or going extinct in the process of adapting or dying in response to ever-changing physical environments.
