GEOLOGY

Detailed explanation-1: -“ Clastic rocks are rock fragments that are compacted and cemented together. Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded.

Detailed explanation-2: -A clast is a fragment of rock or mineral, ranging in size from less than a micron (too small to see) to as big as an apartment block.

Detailed explanation-3: -Most clasts larger than sand size (greater than 2 millimetres) are actual fragments of rock, and commonly these might be fine-grained rock like basalt or andesite, or if they are bigger, coarse-grained rock like granite or gneiss. Sedimentary rocks that are made up of “clasts” are called clastic sedimentary rocks.

Detailed explanation-4: -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-5: -Clastic Sedimentary Rocks Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone. Sandstone is medium-grained, meaning its fragments are between 1/16 mm and 2 mm.
