How does plate tectonics and geological events affect the environment?

The main effects from plate tectonics are the uplift of mountains which results in snow covered mountains. These increase planetary albedo cooling the planet. This partly accounts for the current Pleistocene Ice Age, with the growth of the Alps, Rockies, Andes and Himalayas all snow covered. During the Cretaceous there was little mountain building, and the sea surface was greater due to erosion around the coasts. This led to an increased greenhouse effect from water vapour and higher temperatures globally
