Less Important Processes

Question 1

Greenhouse Effect (4 steps)

Question 2

Ocean acidification (4 steps)

Answer 2

1) Carbon dioxide from the atmosphere is absorbed by the ocean.
2) Carbon dioxide absorbed by the ocean is broken down, forming carbonic acid and hydrogen ions.
3) As hydrogen ions form bonds with carbonate atoms, bicarbonate atoms form. The concentration of carbonate atoms is therefore reduced.
4) Shells and coral of marine life are calcium-based, and organisms use carbonate atoms to build and maintain these structures.
