What is a carbon sink/reservoir?
A place that absorbs carbon
A place with no carbon
A place that releases carbon
What is the largest sink/reservoir of carbon on the planet?
Atmosphere
Ocean floor
Ocean surface
What is the role of greenhouse gases, like carbon, in the atmosphere?
release heat
trap heat
no effect on temperature
What has caused an increase in atmospheric CO2 levels in the last 200 years?

Ocean currents
Natural events
There is more carbon on Earth today than there has been in the past.
True
False
What is the carbon cycle?
The process of carbon absorption by plants
The formation of fossil fuels
Nature's way of reusing carbon atoms
Carbon is absorbed and stored in carbon sinks/reservoirs, such as rocks, living things, the atmosphere, and the ocean.
True
False
