the movement of sediments from one place to another
the breaking down of rocks into smaller pieces
the dropping off of sediments in a new location
the heating and cooling of earth’s surface

2 multiple choice 1 point
which process is responsible for moving rock particles by wind, water, or ice?
weathering
erosion
deposition
melting

Explanation:

Weathering is the physical, chemical, or biological breakdown of rocks into smaller pieces. Erosion is the process of moving rock - particles by agents like wind, water, or ice. Deposition is the dropping - off of sediments in a new location. The heating and cooling of Earth's surface can be a factor in weathering but is not the definition of weathering. Melting is a change of state from solid to liquid and is not related to moving rock particles by wind, water, or ice.

Answer:

1. The breaking down of rocks into smaller pieces
2. Erosion
