What is delta made of

sediment, typically silt, that is eroded into a river

Explanation:

Deltas are land forms created at or near the mouths of rivers. They are caused by sediment, typically silt, that is eroded into a river and carried to its mouth, where the sediment is deposited.

When I think of the word 'delta' I typically think of mud, silt, and sand (or, ahem, clastic detritus) as the construction material.

Explanation:

Deltas are accumulations of sediment that form where a river meets a standing body of water. Over time a depositional feature builds out into the body of water. When I think of the word 'delta' I typically think of mud, silt, and sand (or, ahem, clastic detritus) as the construction material.
