What are particles of rocks, minerals, and remains of plants and animals collectively called?

The term "sediment" refers to particles of rocks, minerals, and the remains of plants and animals that are transported and eventually deposited by water, wind, or ice. Sediments can accumulate over time and contribute to various geological processes, such as the formation of sedimentary rocks. This definition encompasses a wide range of particle sizes, including sand, silt, and clay, underscoring its broad application in understanding various environmental and geological contexts.

While "soil" encompasses a mix of organic material, minerals, air, and water that supports plant life, it is a specific subset of sediment that has undergone significant weathering and biological activity. "Grounds" is not a geological term commonly used to describe these materials; it's a more general term referring to land or surface area. "Silt," on the other hand, specifically refers to fine particles that are smaller than sand but larger than clay, making it just one category within the broader definition of sediment. Thus, "sediment" is the most encompassing and accurate term for these materials as a whole.
