Here's why:
* Clast refers to a fragment of rock or mineral that has been broken from a larger rock.
* Clasts are formed through various processes like weathering, erosion, and transportation.
* The size and shape of clasts can vary greatly depending on the process that created them.
Examples of clasts:
* Gravel: Large clasts (bigger than 2mm)
* Sand: Medium-sized clasts (between 0.0625 mm and 2 mm)
* Silt: Fine clasts (between 0.0039 mm and 0.0625 mm)
* Clay: Very fine clasts (smaller than 0.0039 mm)
These clasts can then be cemented together to form sedimentary rocks, like sandstone, conglomerate, and shale.
