Quizplus · Accepted Answer

Sedimentary rocks are formed from sediment that has been weathered and eroded from preexisting rocks, transported and deposited by water, wind, or ice, and then compacted and cemented together. Sedimentary rocks cover about 75% of the Earth's surface and are the most common type of rock found at the surface. Intrusive igneous rocks, extrusive igneous rocks, and metamorphic rocks are all less common at the Earth's surface compared to sedimentary rocks.
