Question
Wind shapes Earth's surface mainly through three processes: erosion, transportation, and deposition.
Erosion: Wind picks up and removes loose particles like sand, dust, and soil from the ground. This happens especially in dry, barren areas where vegetation is sparse. The wind's force can wear down rocks and soil surfaces over time, smoothing and reshaping them.
Transportation: Once particles are lifted, wind carries them over distances. Smaller particles like dust can travel far in the atmosphere, while sand grains tend to move closer to the ground, often bouncing or rolling along the surface—a process called saltation.
Deposition: When the wind slows down, it drops the particles it’s carrying. This creates features like sand dunes, loess deposits (fine silt), and other sediment accumulations that build up and change the landscape.

All of them. Each sentence describes one of the wind-shaping processes:
- "Wind can move rock and sediments along the ground." — transportation (saltation/creep).
- "Wind can move sediment to a different location." — transportation (and long‑distance dust transport).
- "Wind can scour Earth's surface and clean rocks." — erosion/abrasion.
- "Wind can create and change sand dunes." — deposition.
- "Wind can move rock and sediments along the ground." — transportation (saltation/creep).
- "Wind can move sediment to a different location." — transportation (and long‑distance dust transport).
- "Wind can scour Earth's surface and clean rocks." — erosion/abrasion.
- "Wind can create and change sand dunes." — deposition.
