The correct answer is talus. Let me explain in detail.
Talus is a type of soil that is transported and deposited by gravitational forces. This type of soil is typically found at the base of cliffs or steep slopes and is formed as a result of rockfall and other slope failures.
Here are some key points about talus:
Talus is a type of soil that is transported and deposited by gravitational forces. This type of soil is typically found at the base of cliffs or steep slopes and is formed as a result of rockfall and other slope failures.
Here are some key points about talus:
- Formation: Talus is formed through the accumulation of rock fragments and debris that have fallen from a higher elevation due to weathering, erosion, or slope instability.
- Characteristics: Talus soil is generally coarse, angular, and poorly sorted, with a wide range of particle sizes. The soil is often unstable and susceptible to further movement due to its loose nature and steep slopes.
- Location: Talus is commonly found at the base of mountain cliffs or steep slopes where rockfall and other slope failures are frequent.
- Role of gravity: Gravitational forces play a crucial role in the transportation and deposition of talus soil. As rocks and debris break off from a slope, gravity pulls them downhill, causing them to accumulate and form talus deposits.
In contrast, other types of soil mentioned have different transportation mechanisms:
- Loess: Loess is a wind-blown (aeolian) deposit consisting predominantly of silt-sized particles.
- Drift: Drift soil is a general term for material deposited by glaciers or ice sheets, so its transportation mechanism is glacial movement.
- Dune sand: Dune sand is transported and deposited by wind, forming sandy mounds or ridges in desert regions or along coastlines.
In summary, among the given options, talus is the type of soil that is transported by gravitational forces, as it accumulates at the base of slopes due to the downhill movement of rock fragments and debris.

Transportation of Soil by Gravitational Forces
Soil transportation is the movement of soil from one place to another by various natural agents such as water, wind, ice, and gravity. Among these agents, gravitational forces are responsible for the transportation of certain types of soil.
Types of Soil Transported by Gravitational Forces
Among the given options, the type of soil that is transported by gravitational forces is talus.
Talus is a type of soil that is formed by the accumulation of rock debris at the base of a cliff or a steep slope due to gravitational forces. It is composed of angular rock fragments and boulders that have fallen from the cliff or slope above. The debris accumulates gradually, forming a cone-shaped deposit of soil called a talus slope or talus cone.
The transportation of talus soil is mainly due to gravitational forces acting on the rock fragments and boulders. The rock fragments and boulders gradually move down the slope due to gravity and accumulate at the base of the slope, forming the talus soil.
Other Types of Soil Transported by Natural Agents
Other types of soil that are transported by natural agents are:
1. Loess - transported by wind
2. Drift - transported by glaciers
3. Dune sand - transported by wind
Conclusion
In summary, the type of soil that is transported by gravitational forces is talus. The transportation of talus soil is mainly due to the action of gravity on the rock fragments and boulders that have fallen from the cliff or slope above.
