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".

Sedimentary rock
The movement of rock fragments is called erosion.
Breccia is the type of sedimentary rock that is made of other fragmented rocks. The mineral that holds the fragments together can be made from the same rock material as the larger fragments, or from a different type of rock entirely.
Mineral fragments in soil come from the weathering and breakdown of parent rock material over time. Physical, chemical, and biological processes break down larger rock particles into smaller mineral fragments, which become part of the soil composition. These mineral fragments provide essential nutrients for plants and help determine soil properties.
The layer of rock and mineral fragments produced by weathering and covering nearly all of Earth's land surface is called regolith. Regolith is made up of various sizes of rock and mineral particles that result from the breakdown of bedrock over time due to weathering processes.
The rock and mineral fragments in soil come from the breakdown of parent rock through processes like weathering and erosion. Over time, physical, chemical, and biological factors contribute to the decomposition of rocks into smaller fragments that make up soil.
Unchanged rock and mineral fragments
Breccia is the type of sedimentary rock that is made of other fragmented rocks. The mineral that holds the fragments together can be made from the same rock material as the larger fragments, or from a different type of rock entirely.
A clastic rock.
