Destructive landforms
Valleys/Canyons
Valleys and canyons can be made in many ways. They can be made by water, wind, and glaciers. The valleys are formed when wind, water, or glaciers carry away sediments. Over time these destructive forces gouge a valley into earth's surface. Some examples of a valley is,
-Grand canyon
- Black canyon
-Great Rift Valley
-Death Valley
Sometimes, glaciers can gouge earth's surface and make a lake. An example of this is, Lake Erie.

Sinkhole
Sinkholes are becoming more and more common in the US. These strange holes are formed when water seeps into the ground. It then goes into a limestone layer. The slightly acidic water breaks down the limestone forming a cave . Things like new construction and gravity can cause the soil on top of the cave to collapse, making a sinkhole. Some sinkholes are so large that they can swallow whole houses. Areas that have many sinkholes include,
-Florida
-Alabama
-Missouri

Terms
Valley- A low area of land between hills or mountains, typically with a river or stream flowing through it.
Canyon- A deep gorge, typically one with a river flowing through it.
Sediment- bits of rock made by a destructive force.
Sinkhole- A cavity in the ground, common in limestone bedrock, caused by water erosion and providing a route for surface water to disappear underground.
