Explanation: Silt is granular material of a size somewhere between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil or as sediment mixed in suspension with water (also known as a suspended load) in a body of water such as a river. Silty soil is usually more fertile than other types of soil, meaning it is good for agriculture.

Colluvium is a type of parent material that moved down slope due to gravitational forces (in some cases water may play a role in initiation of the movement). Colluvium is heterogeneous, unsorted material of all particle sizes (from boulders to clay) with relatively little abrasion to round the particles. Consequently, colluvium consists of very sharp, angular rock fragments accumulated at the base of steep slopes.
Aeolian soil : A type of soil that is transported from one place to another by the wind.
Alluvium  is loose, unconsolidated (not cemented together into a solid rock) soil or sediments, which has been eroded, reshaped by water in some form, and redeposited in a non-marine setting.
Glacial soil  Unsorted, non-stratified glacial deposits consisting of clay, silt, sand, and boulders transported and deposited by glacial ice.

Black soil is used to make matkis and surrahis. This is because it provides proper support due to air spaces between their particles. It can also retain water for a long period of time. Along with this, it can withstand a large amount of climatic change also.
