Proponents of Young Earth Creationism, who hold to the belief planet only about 6000 years old, preach vast sedimentary deposits the. THE EARTH’S CRUST The whole earth made rocks & minerals help students answer central question how stripes formed? igneous created melted magma deep inside surface.
Inside earth, there liquid core molten and on outside, hard crust teach process creating rock.
