Final answer:
Water, wind, ice, and gravity are the four types of erosion.
Step-by-step explanation:
The four types of erosion are water, wind, ice, and gravity.
Water erosion occurs when water carries away soil particles, creating channels or gullies. Wind erosion happens when wind blows and carries away loose soil particles, leading to the formation of sand dunes. Ice erosion occurs when frozen water expands in cracks, leading to the breaking down of rocks. Gravity erosion occurs when gravity pulls rocks and soil downhill, causing landslides or rockfalls.
