The landform that is evidence of wind erosion is sand dunes.
The landform that is evidence of wind erosion is sand dunes.
To understand why sand dunes are formed by wind erosion, let's break it down:
1. Wind erosion: Wind erosion occurs when the force of wind carries and moves particles of sediment, like sand, from one location to another. Over time, this action can shape the land and create distinct landforms.
2. Sand dunes: Sand dunes are formed when wind blows loose grains of sand and deposits them in a specific area. These deposits eventually pile up, forming hills or ridges of sand, which we commonly refer to as sand dunes. The shape and size of the dunes depend on factors like wind speed, direction, and the availability of sand.
So, when you see sand dunes in an area, it is evidence that wind erosion has been at work, sculpting the landscape by moving and accumulating sand particles into these distinctive formations.
