In General, Warm, Wet Climates Allow for Fast Formation of Soils

In general, warm, wet climates allow for fast formation of soils primarily because

A) chemical weathering proceeds at rapid rates.
B) parent material found in warm, wet climates tends to allow it to break down faster than the types of parent material found in colder climates.
C) physical weathering proceeds at rapid rates.
D) there is less biological activity in warm, wet climates than elsewhere.
