Question

what is formed by weathering, erosion, and deposition?
○ sand dunes
○ mountains
○ grasslands
○ volcanoes

Explanation:

Weathering breaks down rocks, erosion transports the broken - down materials, and deposition deposits these materials. Sand dunes are formed when wind (a form of erosion) transports sand particles (produced by weathering of rocks) and then deposits them. Mountains are mainly formed by tectonic plate movements (not directly by weathering, erosion, and deposition). Grasslands are mainly related to climate and plant growth patterns. Volcanoes are formed by magma rising from the Earth's interior.

Answer:

sand dunes
