Question

oh sorry! by mistake i wrote slit but it was silt so the question is what do you mean by silt?

Answer 1

Silt: fine sand, clay, or other material carried by running water and deposited as a sediment, especially in a channel or harbour.

Answer 2

Silt is granular material of a size between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water (also known as a suspended load) and soil in a body of water such as a river.
