qThe uplifting weathering hypothesis asserts that the global mean rate of
chemical weathering is heavily
affected by the availability of fresh rock and mineral surfaces that the weathering
process can attack.
qThis hypothesis suggests that tectonic uplifting enhances the exposure of freshly fragmented rock which is an important factor in the intensity of
chemical weathering.
qThis hypothesis looks at chemical weathering as the active driver of climate change, rather than as a
negative feedback that moderates climate changes.
