Answer:

Water, Ice, Wind and Gravity

Explanation:

The four agents of erosion, or the transport and removal the products of weathering, are water, wind, gravity, and glaciers. *Note: water and ice are sometimes thought as one agent, making three agents of erosion total (water, wind, and gravity).

Water, whether in the form of a stream, an ocean, or even heavy precipitation, transports sediments. In the image below, the water has worn away the rock and these rock sediments have been transported elsewhere.

During wind erosion, moving sediments are picked up by the wind and are transported depending on the strength of the wind and the mass of the sediment.

Gravity also causes erosion. This process can happen gradually over time or more quickly, such as during a landslide or avalanche.

Finally, glaciers transport sediment when they move. This process occurs very slowly, but as a glacier moves across land, it picks up and distributes sediments. In the image below, you can see how the contact between the ice and the earth disrupts sediments. These sediments become trapped in the ice and moved.

As you can see in the image below, glaciers aren't just ice.

Answer:

Wind, water, gravity, and ice

Explanation:

Water can erode soil material. Especially if the soil is bare, dry and erodable erosion via rain particles can occur.

Wind is another factor that cause soil erosion. Dry soil particles (especially if they are fine) can move to other areas if wind exists.

Ice is another issue on erosion. Ice, when it is melting, can carry soil particles.
