What is the process by which water, ice, wind, or gravity moves weathered rock and soil?

• Deposition

• Erosion

• Condensation

• Precipitation

What is the main difference between weathering and erosion?

• Weathering involves the movement of rock, while erosion involves the breaking down of rock

• Weathering occurs only with water, while erosion can occur with water, air, and biological factors

• Weathering is the process of breaking down rocks into smaller pieces, while erosion is the movement of those pieces to new locations

• There is no difference; they are part of the same process

What role do decomposers play in an ecosystem?

• They produce their own food through photosynthesis

• They consume living plants and animals
