What are the erosional agents?

Answer 1

There are four agents of erosion, which may or may not be aided by gravity:

• Running water (Fluvial erosion)
• Seas and Oceans (Marine erosion)
• Wind (Aeolian erosion)
• Ice (Glacial erosion)

Answer 2

Weathering is a process by which rocks and minerals are gradually broken down into smaller and smaller particles.

Causes of weathering in rock:

• Acid dissolution
• Oxidation
• Sunshine
• Hydrolysis
• Plant growth hydraulics
• Wave action
• Frost wedging
• Release from compressive forces
• Crystallizing salts
• Animal movements
• Abrasion

Weathering of rocks is caused by chemical and mechanical means. Slightly acidic rainwater can react with rock surfaces, dissolving them over time. Rocks can also be affected by organic sources of chemical reactants. Heat from the sun can cause differences in temperature between the surface and the interior of a rock which can cause a loosening of the surface called exfoliation. Liquid water penetrates cracks in the rocks surface where it can freeze and expand, opening up the cracks for further attack in tandem with acidic rainwater. Plant root growth can also cause cracks to further expand, making them more vulnerable to frost expansion and chemical attack. Underlying rock which is exposed due to erosion of the overlying rock becomes free of the pressure it was previously exposed to, causing the rock to expand and break apart. Other means of weathering include the expansion of crystallizing salts that have been taken in by a rock surface, expansion due to the absorption of water, and hydraulic action from crashing waves on seashore rock formations.

Answer 3

An agent of erosion is something that could lead to erosion's occurrence. Erosion is the movement of sediment from one place to another place. The agents of erosion are wind, water, ice and gravity.
