How does acid rain cause chemical weathering of rock?

Answer 1

1. Acids fom living things

2. Acid precipitation

3. Acids in groundwater

Living things- When living things touch rock, some of the acids are transferred to the surface of the rock.

Acid presipitation-Sometimes rain, sleet, or snow contains more acid than usual.

Acids in groundwater-When ground water touches rock a reaction happens and it dissolves the rock which can cause caves.

Answer 2

Biological WeatheringBiological weathering would include the effect of animals and plants on the landscape. This is more than roots digging in and wedging rocks. Biological weathering is the actual molecular breakdown of minerals. There are things calledlichens(combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area. You might find more activities like lichens near oceans where the air is humid and cooler.

Answer 4

Acid rain does not cause weathering of all rocks. Calcium carbonate rocks, like gravel, are very susceptible to weathering by acid rain. The acid reacts to break doen the calcium carbonate into carbon dioxide and other calcium compounds

Answer 5

the acids erode the rock away.
