Here's why:

* Sediment is the general term for loose, unconsolidated material that is the product of weathering and erosion.

* Mineral particles are the basic building blocks of rocks, and they are often found in sediment.

* Loosely held together means that the particles are not cemented or bound together by a hard matrix.

Sediment can be found in various forms, such as:

* Sand: Composed of relatively coarse mineral particles.

* Silt: Composed of fine-grained mineral particles.

* Clay: Composed of very fine-grained mineral particles.

Examples of sediment:

* Sand on a beach

* Silt in a river bed

* Clay at the bottom of a lake

* Dust in the air
