Which of the following types of soils is transported by gravitational forces?

Explanation:

Gravity deposits:

• Gravity can transport materials for short distances.
• Gravity deposits are termed colluvial soils or talus.
• These soils are found in the mountain valleys and are formed by gravity force.

Wind transported soil:

• Like water, wind can erode, transport, and deposit fine grain soils. The soils that have been transported and deposited by wind are called 'Aeolian deposits'
• Example: Dune sand and Loess
• when the soil is wet it becomes soft and compressible because cementing action is lost and it collapses.

Water transported soil: These sedimentary deposits are of three types

• Alluvial​ Deposit: Deposited from suspension in running water
• Lacustrine deposit: Deposited from suspension in still, freshwater of lakes
• Marine deposit: Deposited from suspension in seawater.

Glacial deposits:

• Glaciers are large masses of ice formed by the compaction of snow.
• The melting of a glacier cause deposition of all the materials and such a deposit is referred to as till.
• Drift is a general term used for the deposits made by glaciers directly or indirectly.
