Question

Fill in the blank.
 _ _ _ _ _ _ _ _ _ _ is the third nearest planet to the sun.

Answer 1

Hint: The solar system consists of the sun and eight other planets. The Earth is one of the eight planets of the solar system and one of the four made of rocks. It is unique because it is the only planet in the solar system and perhaps even in the universe that can support life.

Complete answer:
Earth is the third planet from the sun. The distance of the earth from the sun makes it neither very hot like the planet Venus nor icy cold like Neptune, enabling liquid water to exist on its surface. The earth also has an oxygen-rich atmosphere and the two important substances that are water and oxygen are the key factors that allow life to flourish on the Earth. The earth orbits around the sun and it is simultaneously spinning on an imaginary line known as the axis which runs from the North Pole to the South Pole.
Scientists believe that the earth was formed roughly at the same time as the sun and the other planets around 4.5 million years ago. The earth is covered in a layer of gases known as the atmosphere and this atmosphere not only nourishes and protects life on earth but also burns up the meteorites from entering the earth’s surface.

Note: Like the planets such as Venus and Mars, the Earth has mountains, valleys and volcanoes. Almost 70 percent of the earth’s surface is covered in oceans of liquid water that averages about 2.5 miles deep.
