JudyWind erosion and deposition in deserts can form landforms such as sand dunes, desert pavements, ventifacts (rocks shaped by abrasion), and loess deposits. These landforms are shaped by the movement of sand and other particles carried by the wind, creating distinct features in desert landscapes.

Are headlands made from erosion or deposition?
Headlands are typically formed by erosion, as the action of waves, currents, and weathering wears away the coastlines, creating protruding landforms. Erosion removes softer rock and sediment, leaving harder rock to form headlands that jut out into the water.
How do erosion and deposition work together to form a delta?
Erosion carries sediment downstream, and when the water flow slows as it reaches a body of water like a river or ocean, deposition occurs. The sediment settles and accumulates, building up landforms like deltas. The continual cycle of erosion and deposition helps form the intricate network of channels and sediment buildup that characterize a delta.
What are some of the features formed by underground erosion and deposition?
Underground erosion can form caves, sinkholes, and underground rivers. Deposition can result in formations such as stalactites, stalagmites, and flowstone.
Is a sinkhole erosion deposition?
A sinkhole is not a form of erosion or deposition. Sinkholes are formed when underground rock, typically limestone, dissolves and collapses, creating a hole at the surface. Erosion is the process of wearing away rocks and soil, while deposition is the laying down of sediments.
Is a drumlin created by erosion and deposition?
Yes, a drumlin is created by a combination of erosion and deposition processes. It forms when glaciers deposit sediments in an elongated mound shape due to the movement of the ice. Erosion from the glacier's movement and deposition of materials help shape drumlins into their characteristic streamlined form.
