Blowout: a depression created by wind erosion typically in either a partially vegetated sand dune ecosystem or dry soils (such as a post-glacial loess environment).[1]
Area of subsidence caused by the collapse of an underlying structure, such as sinkholes in karst terrain.
Sink: an endorheic depression generally containing a persistent or intermittent (seasonal) lake, a salt flat (playa) or dry lake, or an ephemeral lake.
Panhole: a shallow depression or basin eroded into flat or gently sloping, cohesive rock.[2]
Collapse-related:
Sinkhole: a depression formed as a result of the collapse of rocks lying above a hollow. This is common in karst regions.
Kettle: a shallow, sediment-filled body of water formed by melting glacial remnants in terminal moraines.[3]
Sedimentary basin: in sedimentology, an area thickly filled with sediment[1] in which the weight of the sediment further depresses the floor of the basin.
Oceanic trench: a deep linear depression on the ocean floor. Oceanic trenches are caused by subduction (when one tectonic plate is pushed underneath another) of oceanic crust beneath either the oceanic crust or continental crust.
A basin formed by an ice sheet: an area depressed by the weight of the ice sheet resulting in post-glacial rebound after the ice melts (the area adjacent to the ice sheet may be pulled down to create a peripheral depression.)[4]
