Unit 6 Ocean Acidification Checkpoint

Front

What happens to water when it is dissolved with carbon dioxide?

Back

It becomes more acidic.

Front

Why is ocean acidification considered a risk to fish populations?

Back

It eliminates food sources for these species.

Front

What is the chemical formula for carbonate ion?

Back

CO₃²⁻.

Front

What do many marine organisms use to make their shells?

Back

Calcium and carbonate (CO₃²⁻).

Front

What is a substance with a pH less than 7 called?

Back

Acid.

Front

What is ocean acidification?

Back

The decrease in pH of ocean water due to increased carbon dioxide absorption.

Front

What is the pH range of acidic solutions?

Back

Less than 7.

Front

What role do carbonate ions play in marine ecosystems?

Back

They are essential for the formation of shells and skeletons in marine organisms.

Front

How does increased carbon dioxide in the atmosphere affect ocean chemistry?

Back

It leads to higher levels of carbonic acid, lowering the pH of ocean water.

Front

What is the impact of ocean acidification on coral reefs?

Back

It weakens coral structures, making them more susceptible to damage.
