Which of these is an input to the drainage basin system?

• Trees

• Precipitation

• Infiltration

• Groundwater flow

Which of these is an output of a woodland carbon cycle?

• Trees

• Burning

• Dissolved carbon within runoff

• Production of glucose through photosynthesis

If climate change causes temperatures to rise and permafrost melts, releasing more trapped greenhouse gases, further raising temperatures. What sort of feedback is that?

• Negative

• Positive

If increased CO2 in the atmosphere leads to increased temperatures, encouraging photosynthesis so removing CO2 from the air and counteracting the rise in temperatures, which sort of feedback is it?

• Negative

• Positive

What is the key term for a state of balance in a constantly changing system?

• Dynamite equivalent

• Dynamo equipment

• Dynamic equilibrium

• Dynasor extinctium

• Open

• Closed

Is the carbon cycle in a forest an open or closed system?

• Open

• Closed

Which of these is a flow in a drainage basin?

• Puddles

• Trees

• Precipitation

• Infiltration

What is the key term that means the individual elements or parts of a system?

• Input

• Output

• Stores/ components

• Flow/ transfers

Which is the key term in a systems approach that means the links or relationships between the components?

• Inputs

• Energy

• Stores/ components

• Flows/ transfers
