The following information is about Weathering.
Weathering Defined
Weathering includes two surface or near-surface processes that work in concert to decompose rocks. Both processes occur in place. No movement is involved in weathering. Chemical weathering involves a chemical change in at least some of the minerals within a rock. Mechanical weathering involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within it. Mechanical weathering includes processes such as water in cracks freezing and expanding, or changes in temperature that expand and shrink individual minerals enough to break them apart.
This definition is in context to Geologic. See more contextual defintions for Weathering.
Green power saved Earth from "˜ice ball"™ fate
Published July 2, 2009, 2:50 pm, Gulf Times
Vegetation helped save Earth from runaway cooling that would have encased the planet in ice, according to a study published on Wednesday.
Mid-Pliocene Asian Monsoon Intensification And The Onset Of Northern Hemisphere Glaciation
Published July 1, 2009, 9:20 pm, Science Daily
The late Pliocene onset of major Northern Hemisphere glaciation is one of the most important steps in the Cenozoic global cooling. Although most attempts have been focused on high-latitude climate feedbacks, no consensus has been reached in explaining the forcing mechanism of this dramatic climate change.
Plants Kept Earth From Becoming Ice Ball

Plants Save the Earth from an Icy Doom (w/ Podcast)
Published July 1, 2009, 11:18 am, PhysOrg
(PhysOrg.com) -- Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers at Yale University, the Carnegie Institution of Washington and the University of Sheffield now show that land plants saved the Earth from a deep frozen fate by buffering the ...
