mechanical erosion मीनिंग इन हिंदी

By contrast to mechanical erosion, FAC involves dissolution of normally poorly soluble oxide by combined electrochemical, water chemistry and mass-transfer phenomena.
Such fine material can be generated easily via mechanical erosion from feldspar-rich basalts, such as rocks in the southern highlands on Mars.
Chemical and mechanical erosion of the old lava flows is caused by reactions of the surface with the atmosphere in the presence of carbon dioxide and sulfur dioxide ( see carbonate-silicate cycle for details ).
This occurs because in regions of higher elevation there are higher rates of mechanical erosion ( i . e . gravity, fluvial processes ) and there is constant exposure and availability of materials available for chemical weathering.
Over long periods of time, as the landscape was lowered further by weathering and erosion, the silcrete became exposed at the surface as a lag gravel, an armoured carapace of " gibbers " ( also known as a " desert pavement " ), protecting the weaker regolith below from mechanical erosion.
