Ocean and CO2 Absorption Flashcard

Front

When CO2 is dissolved in water, what is formed?

Back

Carbonic acid

Front

Carbonic Acid breaks down into which components?

Back

Hydrogen ions and bicarbonate

Front

As carbonic acid breaks down, what element is specifically responsible for the drop in pH?

Back

Hydrogen

Front

What possible complications can arise from a decline or disappearance of shellfish and corals from marine ecosystems?

Back

Disruption of food chains

Front

Why are pteropods considered the “canary in a coal mine” for ocean acidification?

Back

They are highly sensitive to pH changes

Front

Where is ocean acidification expected to occur more rapidly?

Back

In polar regions

Front

Why is the current drop in ocean pH different from previous occurrences?

Back

It is happening more rapidly

Front

About how much CO2 do oceans absorb?

Back

30%

Front

What happens to the amount of carbonate in the water as pH drops?

Back

It decreases

Front

How does the carbonate level affect marine animals?

Back

It is essential for their shells
