Inputs And Outputs Of The Carbon Cycle

Question 1

Precipitation

Question 2

Photpsynthesis

Question 3

Decomposition

Answer 3

Buried beneath younger sediments to form carbonaceous rocks eg, coal,m ignite,oil and natural gas Which acts as a carbon sink for millions of years (slow carbon cycle)

Question 4

Weathering

Answer 4

Carbon-rich sedimentary rocks near the surface exposed to erosion and tectonic movement face chemical weathering

Carbonation - precipitation charged with co2 from the atmosphere forming a weak acid. The acid attacks carbonate minerals in rocks, which releases co2 to the atmosphere and rivers and oceans ( dissolved form of co2) ( slow)

Question 5

Respiration

Question 6

Combustion
