Hint: Think about what we did in the Carbon Cycle Gizmo

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.

Urban areas have a high percentage of impermeable surfaces such as roofs and roads. Which of the following changes would you expect to occur in the water cycle?
