Write notes on Karst topography.
Answers
Karst topography formed from the dissolution of soluble rocks such as limestone , dolomite and gypsum . It is characterized by underground drainage systems with sinkholes and caves . It has also been documented for more weathering-resistant rocks,such as quartite , given the right Conditions.
Karst topography
Explanation:
Karst topography is an area of land characterized by barren, rocky ground; caves; sinkholes; underground rivers; and the absence of surface streams and lakes.
Groundwater erosion may lead to the formation of karst topography, which includes caves and sinkholes. Karst topography is land filled with caves, sinkholes, and underground lakes. A sinkhole occurs when a cave grows to the surface, causing the ground to collapse.
Stalagmites, sinkholes, and stalactites are created by groundwater erosion and deposition. Groundwater erosion can be prevented in several ways.
- Plant trees and other vegetation.
- Decrease the slope of riverbanks.
- Avoid soil compaction (the packing down of soil).
- Build drains and ditches with adequate outlets.
