What are broad shallow depressions excavated by deflation?

Broad shallow depressions excavated by deflation are known as blowouts. These features occur in arid or semi-arid environments where strong winds erode loose, dry soil or sediment, creating depressions in the landscape. Blowouts can vary in size and shape and often lead to the exposure of underlying materials, such as sand, gravel, or clay. They play a significant role in shaping desert landscapes and can impact local ecosystems by affecting water drainage and vegetation patterns.
