diorite,gabbro, granite, pegmatite, and peridotite.

    Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution.

The original rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes. Examples of these rocktypes include marble, slate, gneiss, schist.

The process may be natural or accelerated by human activity. The rate of erosion may be very slow to very rapid, depending on the soil, the local landscape, and weather conditions. Water erosion wears away the earth's surface.

It is a common phenomenon occurring mostly in flat, bare areas; dry, sandy soils; or anywhere the soil is loose, dry, and finely granulated.

It is different from a rock, which can be an aggregate ofminerals or non-minerals and does not have a specific chemical composition.
