Physical Geography Articles - Essay ExampleThis article tries to define keystone dune and ripples and the cause-effect relationship. The author argues that sand dunes are takings of sand waves which piles up with a particular pattern over a large area mostly of desert. However, the article shows that bedforms that result to such land forms are not only caused by wind but any other fluid. It is therefore important to note that climate component which in turn influences movement of wind and water is responsible for the various landforms that characterize Earth surface. The central idea of the article is that Dunes and ripples are considered bedforms.Increasing changes in global climate has significant effect on various land forms. The deserts are particularly in danger as temperatures plummets and humidity dwindles. The fiddling vegetation that covers desert landforms is at the brink of complete elimination. In other words, deserts that already have scanty vegetation cover are poss ible to be transformed to bare land. This would lead to other features like sand dunes among others. Besides, the trend in the desert change is closely associated with rising water levels callable to increasing global temperature that melts ice. This article therefor offers an insight into the complex consequences of climate change of various landforms.This article centers on the unforeseen benefits of global warming as the ice melts. The Glacial melt constitute shift of more iron deposits which are seen as facilitating growth of phytoplankton. These phytoplankton in turn help in bewitching excess carbon dioxide with marginal reduction in greenhouse effect. This fertilization observation is attributed to the silver lining that can be observed on cold landscapes. The author of the article therefore offers an insight into the existing relationship between physical geography and climate
