Processes that shape the earth: II – A presentation by ACWADAM

This presentation by ACWADAM deals with processes that scour the earth’s surface while simultaneously building it elsewhere. The presentation deals with weathering, erosion and deposition of rocks -Read More

  • The process of breaking down and alteration of rocks and formation of new materials from them is known as weathering of rocks.
  • The group of processes whereby the materials of the earth’s crust are moved from one place to another by running water (including rainfall), waves and current, glacier ice and wind is known as erosion.  
  • The processes whereby the material being carried during the process of erosion is deposited either through physical processes (such as drop in the velocity of flowing water) or precipitation of dissolved material under a set of conditions for instance, the deposition of limestones from water rich in calcium carbonate is known as deposition.

Processes that shape the earth: Part I – A presentation by ACWADAM

This presentation by ACWADAM on processes that shape the earth attempts to understand the irregularities of the surface of earth so as to consider the movement of groundwater. The earth’s surface is dotted with what is commonly perceived as high grounds or ‘hills’ and the low grounds or ‘valleys’. Hills and valleys result from movements in the earth and the long term processes of breaking-down the earth surface at some places and building it up at others, also called as diastrophism.  Read More
