Question

Quizplus · Accepted Answer

Sedimentary rocks are formed from the accumulation and cementation of particles of pre-existing rocks or organic materials, which are exposed on the Earth's surface. They make up the majority of surface rocks, covering about 75% of the Earth's surface. Extrusive rocks are volcanic rocks that are formed on the surface from the solidification of lava or ash. Intrusive rocks are formed beneath the surface from the cooling and solidification of magma. Metamorphic rocks are formed from the transformation of pre-existing rocks under high temperature and pressure conditions, often deep beneath the Earth's surface. Therefore, sedimentary rocks are the best choice for the majority of surface rocks.
