Ozone in the Upper Atmosphere Makes Life on Earth Possible [edit]. Ozone is a molecule composed of three oxygen atoms, (O 3). Ozone in the upper atmosphere absorbs high energy ultraviolet radiation (UV) coming from the Sun. This protects living things on Earth's surface from the Sun's most harmful rays.
In earth science, erosion is the action of exogenic processes (such as water flow or wind) which remove soil and rock from one location on the Earth's crust, then transport it to another location where it is deposited. Eroded sediment may be transported just a few millimetres, or for thousands of kilometres.
Erosion. 1  Weathering means disintegration and decomposition of the rock without any significant transportation of the resultant product. 2  Erosion is the loosening and carrying away of rock debris by the moving agent operating on the earth surface. 3  Weathering aids erosion by weakening and disintegrating rocks. 4  Erosion in turn aids weathering by 5  ...
