Answer 1

Answer:

Earth is made of rocks and came into existence billions of year ago. ... However, 70% of the surface of the earth is covered by water which we see as the ocean, sea, and rivers and remaining 30% is covered by land. Like other planets earth also moves around the Sun in a fixed way called orbit.
