Question 1

Peat -temp agri

Answer 1

Agricultural soil invertion increases microbial activity, more co2, temperatures increase, more evaporation peatland becomes less water logged , undecayed organisms are uncovered and they decay

Permafrost melts - more c02

Question 2

Oceans - co2

Answer 2

More co2 in atmosphere as a result of increased human activity, temperature rise, sea temperatures rise, inverse relationship between sea temp and the amount of carbon dioxide held - more co2 dissolved from hydrosphere to atmosphere - co2 levels rise - negative albedo affect
