Geology & Acidification

Question 0

Areas that are not susceptible to acid deposition:

Answer 0

Areas with high weathering rates, which produce large amounts of basic cations for neutralisation.

Question 1

Catchments with high weathering rates (carbonates and basalts) can produce large amounts of basic cations year after year. These can

Answer 1

Exchange with acidic cations deposited from the atmosphere and therefore neutralise high rates of acid deposition.

Question 2

Acidification is likely to occur in areas with

Answer 2

Low weathering rates (granites, shales, gneiss, quartz) and where soil formation is slow.

Question 3

Areas with low weathering rates have

Answer 3

Low base cation concentrations, CEC and SAC.

Question 4

Moderate amounts of acid deposition are hard to

Answer 4

Keep up with in areas with low weathering rates; These areas are at risk of freshwater acidification.
