Early bird Earth science

Describes the covering of our planet which is called the earth's crust. Explores the rock in mountains, canyons, under the ocean and the ground where you are standing. Reveals how thin and fragile this crust really is as revealed in cracks in the earth called faults.

Sheets of rock lie beneath earth's soil and water. They are called the earth's crust which is made of minerals, a solid substance which is not alive. Much of the inside or earth is made of rock as well. Rocks may be as small as a grain of sand or as huge as mountains.
