Lithosphere 03
Lithosphere All solid, rocky outer layer of Earth
“ It covers the entire surface of Earth and is made up of the continents, islands, and the ocean floors ” Lithosphere
The distance from Earth’s surface to its center is about 6400 Km. Scientists have drilled holes into Earth as deep as 12 Km. The drills have brought up samples of rock. Using rock samples and other methods, scientists have inferred that the lithosphere averages about 100 km thick. Lithosphere
Biosphere 04
