Mushroom rock

Mushroom rocks are scattered rock outcrops with narrow base and wide top, which can occur under different conditions.

In the arid climate mushroom rocks caused by ground-level wind touches ( corrasion ). Get in vegetation-free environment on sandstorms, edit the isolated rock outcrops like a sandblaster. The heavier and larger particles move more close to the ground and grind the rocks therefore there more strongly than earlier; there is more rock - the " mushroom cap " - will receive.

In humid climates mushroom rock shapes can arise due to differences in hardness in the rock. This requires an underlying hard rock softer layer, which is attacked by the stronger weathering processes. Due to the climate and vegetation conditions, the forms are, however, less pronounced than in the arid area of the desert. Loose stones are a related form type.

Fluvial erosion and surf in coastal areas can produce mushroom rocks.
