Carbon is often called the building block of life as it is found in all organic molecules
Carbon dioxide is a greenhouse gas. What does this mean?
Why is carbon important ?

Why would life be impossible on this planet without this green house gas?

How is carbon dioxide removed from the atmosphere by green plants?
Can you write a word equation for this?
Cycling of carbon dioxide

Oceans are called sinks for carbon dioxide
Carbon dioxide is absorbed by sea water and makes insoluble carbonates
Removal of carbon dioxide by absorption in the oceans

Absorbs carbon dioxide to form carbonates which are insoluble and fall to the bottom of the sea
Absorbs carbon dioxide which forms soluble hydrogen carbonates which remain dissolved in sea water
Seas and oceans act as BUFFERS
Role of the sea
