Some certian types of lichen grow on rocks. These lichen secrete a form of acid that weakens the rock over time. This is an example of: Explain
a
Salt Wedging
b
Abrasion
c
Chemical Weathering
d
Physical Weathering
c) Chemical Weathering
Chemical weathering refers to the process of rock breakdown and alteration due to chemical reactions. In this example, the lichen secretes acid, which reacts with the minerals present in the rock, leading to its gradual weakening and deterioration over time.
