GEOLOGY

Detailed explanation-1: -Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders. Their names are based on their clast or grain size. The smallest grains are called clay, then silt, then sand. Grains larger than 2 millimeters are called pebbles.

Detailed explanation-2: -1) Clastic (detrital) sedimentary rocks are composed of the solid products of weathering (gravel, sand, silt, and clay) cemented together by the dissolved weathering products.

Detailed explanation-3: -Detrital or clastic sedimentary rocks consist of preexisting sediment pieces that comes from weathered bedrock. Most of this is mechanically weathered sediment, although some clasts may be pieces of chemical rocks.

Detailed explanation-4: -Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.

Detailed explanation-5: -These types of sedimentary rocks are called “clastic rocks. “ Clastic rocks are rock fragments that are compacted and cemented together. Clastic sedimentary rocks are grouped by the size of the sediment they contain.
