GEOLOGY

Detailed explanation-1: -Gravel settles nearest to shore and the largest particles, sand is larger than silt, and is deposited next, and silt is larger than clay.

Detailed explanation-2: -Clastic sediments are classified by particle size, with the largest category being boulders. Generally, a boulder is any piece of sediment that is more than 256 millimeters (roughly 10 inches in diameter).

Detailed explanation-3: -Gravel are the largest particles in soil and clay are the smallest. Most soil is really only half mineral.

Detailed explanation-4: -Particles larger than 2.0 mm are called gravel or stones. Most soils contain a mixture of sand, silt and clay in different proportions.

Detailed explanation-5: -Sand-rock fragments or mineral particles that range in diameter from about 1/16 to 2 mm (from 0.002 to 0.08 inches). Gravel-chipped or rounded rock fragments that typically range in diameter from about 3 to 75 mm (0.125 to 3 inches).
