geological carbon cycle

Question 1

how does weathering play a role in carbon cycle

Answer 1

carbonic acid ( atomspheric moisture mixed with carbon) dissolves rocks into components
calcium from rocks is transported where they form bicarbonate to calcite
turns into limestone
sediment is subducted to mantle

Question 2

how do volcanos play a role

Answer 2

carbon subducted into mantle at destructive plates, returns to atomsphere through activity

Question 3

how does leaf litter play a role

Answer 3

leafs that have fell of tress/plants onto surface
decompose- breakdown of organic carbon compound into inorganic
