Rates are accelerated when the following characteristics are present:
Mineral composition and solubility
High temp/high density minerals are highly vulnerable to chemical weathering
Physical features such as joints/fractures
Improved surface area
Climate (high heat/humidity)
Strong solar exposure with high moisture amounts
Organisms
Weathering rates are accelerated by the presence of living organisms, which physically and chemically break down rocks
Factors Accelerating Weathering Rates: Ice and Snow
Weathering rates are accelerated in cold climates where ice and snow are prevalent.
Differential weathering
non-uniform weathering on exposed rock which results in the disintegration of exposed rock in an uneven pattern.
