Deflation Hollows and Caves: Deflation Hollows: Deflation basins, called blowouts, are hollows formed by the removal of particles by wind. Winds blowing from Gobi Desert carry dust to the northern There are different ways to classify landforms, but there are three general categories: landforms that are built (depositional), landforms that are carved (erosional), and landforms that are made by movements of the Earth's crust (tectonic). As long as the wind is strong enough to carry the sand, the sand dunes are mobile and they keep on shifting from Aeolian processes create a number of distinct features, through both erosion and deposition of sediment, including: Aeolian processes involve erosion, transportation, and deposition of sediment by the wind. This coating is made by manganese and iron oxides, which react with other substances that wind transports. Groins, jetties, breakwaters, and seawalls are structures that protect the shore from breaking waves. Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.A similar process, weathering, breaks down or dissolves rock, but does not involve movement.
