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.
