The surface of the Earth is the crust People have not really gone very deep into the Earth. We are in rock that is called the crust of the Earth. The crust is the outer layer of the Earth's surface. Find the crust in the previous picture. The crust consists of rock and soil. The crust is about 70 km thick, so we have not gone very far yet. Humans have only gone 5kilometres deep, and the hole is so small that you can not see it in the crust. Miners in the deep gold mines suer from heat. The deeper they go, the hotter the rock is. 1 Does the crust go under the sea also? Look at the picture of the rocks and sea in this picture below. This is where the ocean meets the land. Does the land go under the ocean? 2 Chapter 2. Surface of the Earth VISIT Video showing the structure of the Earth goo.gl/YXUFE 89
