BEFORE WE START:
Reading and making a graph
Remember:
SOURCES go UP into the atmosphere.
SINKS go DOWN into the ground and water.

Which are the 3 SINKS of CO2?

Which are the 5 SOURCES of CO2?

1

What does it mean to have more sources than sinks of CO2?

TRY to set up how you would graph this data.

1. With the Line Tool, draw the X and Y axes.
