vegetables and fruits. A person who makes roads thinks earth is mountains of hard rock. A sailor thinks

earth is water as far as the eyes can see.The earth is a big ball covered with water, rock, and soil. The

earth is a planet. There are nine planets around our sun.Animals and plants live almost everywhere on the

earth. They can live on the earth because it is not too far from the sun, or too close to the sun. Living things need the sun. The sun keeps them warm. Most living thing-plants, like vegetables, fruits, trees and grass,

and animals-also must have water to live. The earth has over seventy-five(75%)of water on it.
