Unique landforms and patterns of drainage called karst or karst topography primarily form in temperate to tropical regions, though they are found in arid and polar regions too. The common feature shared by all karst landscapes is that they are underlain by chemical sedimentary rocks particularly …

اقرأ أكثرResultWhat is Acid Rain? Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.

اقرأ أكثرResultThe main processes involved in lithification are compaction and cementation. Compaction involves squeezing the sediment into a smaller volume by packing the sediment particles more closely, by removing water from the pore space (desiccation) or by pressure solution at the points where sediment grains contact …

اقرأ أكثرResultThe dominant and almost exclusive geomorphic process in limestone is the processes of solution and deposition by the action of the groundwater. Many depositional forms develop within the limestone caves. The depositional landforms in limestone areas by the action of ground water are stalctites, stalagmites and pillars.
اقرأ أكثرResultIn geography, the term "solution" describes the process of rock formations, such as limestone, being dissolved in a river setting. The chemical process that occurs is one in which carbon dioxide in the presence of water forms carbonic acid that dissolves limestone. The limestone, carbon dioxide and water …
