flows in the carbon cycle

What are examples of slow flows

Volcanic activity, rock formation, weathering, crude oil formation

What are fast flows in the carbon cycle

Photosynthesis, respiration, digestion, combustion, crude oil extraction

What is carbon on earth measured in

Petagrams/ gigatonnes

Define decomposition

Organisms that have died are broken down. They are decomposed by bacteria fungi and worms. Carbon is returned back to the atmosphere as CO2

Define the carbon budget

Refers to total amount of carbon stored and transferred in the carbon cycle. Certain amount that. Can be emitted whilst limiting warming to temperature goals.

Define combustion

The transfer of carbon in organic material to atmosphere by burning

Define carbon sequestration

Carbon being captured and held in sedimentary rocks or fossil fuels

Define weathering within the carbon cycle

Refers to chemical reactions - rain mixes with carbon acid ans slowly dissolves rocks

How does weathering transfer carbon from rocks to ocean

Dissolving rocks hold carbon in solution, which is carried to ocean through the water cycle
