This is a PH scale. A PH scale is something people use to tell what is deadly and what is not deadly. The most deadly things are on 0 and 14 but the most not deadly thing is on 7 such as blood and water





Explain how acidification kills coral and sea life:
The climate change makes the water warmer and the zooxanthellae leaves the
Coral and the coral dies.



Explain what this is:
This is the layers of the ocean. The sunlight is the top of the ocean and that is where the corals are. The bottom of the ocean is called Trenches zone and that is where the sea creatures like planktons live.

if the planktons died then the sea creatures such as baleen whales would die because there is no other food to eat.
