As rain falls through the atmosphere, it picks up CO 2 which dissolves in the droplets. Once the rain hits the ground, it percolates through the soil and picks up more CO 2 to form a weak solution of carbonic acid: H 2 O + CO 2 = H 2 CO 3 . mitosis is a process that results inWebbIn carbonate regions where mechanical erosion prevails, the formation of karst features will cause surface water infiltration and lower the discharge of surface streams. Reduction in stream discharge will decrease the erosional efficiency and cause steepening of the landscape compared to regions with less-soluble bedrock (Ott et al., 2024). mitosis is controlled at the s checkpoint
