Mountains Aren’t As Guilty as Accused.




Green house gas emissions are usually all around us, contaminating the atmosphere we as human live in. Obviously some things cause more than others. There is also other things that do the very opposite, such as pulling molecules like carbon dioxide out of the atmosphere. One of these processes is known as chemical weathering, which occurs when rock turns into soil. Carbon dioxide molecules and rain combine to dissolve rock, and the weathering products, eventually make their way through waterways to the ocean where some become trapped on the ocean bottom and in coral reefs and seashells. For long period of time, it was believed that mountains had very high rates of erosion, mostly because of their steep slopes. The University of Pennsylvania recently studied this; it was proven that the mountains are not as big as contributors to this effect as were thought to be.
