No, Lichen is caused by clean air meaning where ever there is Lichen in that area the air is clean and not polluted.
Lichen.
By they acid in the substances it weathers the rock away.
Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate rocks to break down and release phosphate into soil. Acid precipitation and the chemicals released by lichen can cause the chemical weathering. In physical weathering, processes like wind, rain, and freezing releases particles of rock and phosphate into the soil.

Lichen produce acids that can slowly break down rock in the process of chemical weathering. Acids in water and air also produce chemical weathering.
The most common cause of chemical weathering is oxygen
The most common cause of chemical weathering is oxygen
No, acids cause chemical weathering.
It is a cause of both.
Oxygen is the major gas that is the cause chemical weathering.
mechanical weathering
Lichen eat away at rocks.
