10 marks: open/closed systems

Explain how water and carbon is cycled between major stores through open and closed systems. (10)

What to talk about with water cycle:

• Reservoirs & stores of global water.

• Inputs/outputs of water i.e. water cycle with all processes.

• Flows of water - precipitation, transpiration & condensation - clouds & formation.

What to talk about with carbon cycle:

• Stores & sinks of global carbon.

• Inputs/outputs of carbon i.e. slow & fast carbon cycles.

• Carbon exchanges - precipitation, photosynthesis, weathering, decomposition.

• Carbon sequestration - physical (inorganic) pump & biological (organic) pump.

Name 3 types of cloud?

1. Cumuliform

2. Stratiform

3. Cirrus

what is the equation for carbonation?

Calcium carbonate + carbonic acid = calcium bicarbonate.
