Most are deposited from the land surface to the bottoms of lakes, rivers, and oceans. Sedimentary rocks are normally stratified—

Igneous rocks are those that solidify from magma, a molten combination of rock-forming minerals and usually volatiles like gases and steam. Given that their constituent minerals are crystallized from molten content, igneous rocks are shaped at large temperatures. They originate from processes deep inside the Earth—normally at depths of about 50 to two hundred kilometres (thirty to a hundred and twenty miles)—during the mid- to decreased-crust or from the upper mantle.
