This is a diagram of the carbon cycle.
Label the arrows with the processes they represent.
The gases that make up Earth's atmosphere have changed over time. Scientists measure the levels of carbon dioxide (CO2) in Earth's atmosphere.
The simplified Carbon Cycle Model shows locations where carbon is stored and processes that move carbon from one location to another.
Scientists can use carbon cycle models to help make predictions about the amounts of carbon in different locations.
Use this Carbon Cycle Model to identify all the processes that would decrease CO2 in the atmosphere if the rates of these processes were to increase.
