Radiometric dating of surface rocks

The smallest grains are called clay, then silt, then sand.

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. A crystal is piece of a homogeneous solid substance having a naturally geometrically regular form with symmetrically arranged plane faces.

Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.

If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

When buried, the sediments lose water and become cemented to form rock. Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks.

Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks.

Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders.
