Clasts are rock fragments, also pieces of rock that make up the texture of some sedimentary rock (clastic sedimentary rock).

Fragments or particles.
A clast is a fragment of rock or mineral that is produced by the weathering and erosion of larger rocks. Clasts can vary in size, shape, and composition depending on the parent material from which they originated. They are commonly found in sedimentary rocks.
Sedimentary clasts and grains become rounded primarily through the process of abrasion, where they are repeatedly bumped and rubbed against each other by flowing water, wind, or ice. This abrasion wears down the sharp edges and corners of the clasts, leading to a smoother and more rounded shape over time.
Conglomerate is a coarse-grained sedimentary rock that contains large, rounded sediments called clasts. These clasts are typically pebbles, cobbles, or even boulders that are cemented together by finer sediment particles.
Clasts. An accumulation of fallen clasts at the bottom of a rock face is "scree". An accumulation of clasts generally, up to about cobble size anyway, is a "sediment".
Clasts become rounded through processes like transportation by water, wind, or ice, which wear down their edges and corners. Sorting occurs when clasts of similar size are deposited together as a result of energy differences during transportation – heavier clasts settle out first, while lighter clasts are carried further.
They are referred to as clasts or bio-clasts.
They are referred to as clasts or bio-clasts.
The size, shape, and weight of clasts determine the ability of a carrier to move them. Smaller, rounded clasts are typically easier to transport than larger, angular ones. Additionally, factors like water velocity, wind strength, or glacier movement can influence the transport of clasts.

Rocks that have layers or clasts are typically formed through deposition and compaction of sediments. Sedimentary rocks like sandstone or shale are created when layers of sediment are compressed over time, while conglomerate rocks with visible clasts are formed from the cementation of rounded rock fragments.
In most cases, all we have to date are the clasts in the sedimentary rock. Dating the clasts, however, would yield the age of the source rock from which they were derived rather than the current sedimentary rock.
