Ocean Acidification and Its Effects

What is ocean acidification often referred to as?

• The savior of marine life

• The evil twin of global warming

• A natural ocean process

• A solution to climate change

Why is ocean acidification a concern for marine organisms?

• It makes the water too warm for them

• It makes it difficult for them to secrete calcium carbonate shells

• It increases the oxygen levels in the water

• It causes the water to become too salty

What happens when carbon dioxide dissolves in seawater?

• It forms a weak acid

• It forms a strong acid

• It forms a base

• It has no effect

Which marine organisms are particularly vulnerable to ocean acidification?

• Sharks

• Sea turtles

• Dolphins

• Planktic snails

How does ocean acidification affect Pacific salmon?

• It increases their population

• It has no effect on them

• It reduces their food source

• It makes them grow faster

What have scientists observed in oysters due to ocean acidification?

• They become more colorful

• They cannot secrete their first shells

• They thrive in acidic waters

• They grow larger shells

What historical events have changed the acidity of the sea?

• Increased rainfall

• Decreased sunlight

• Massive volcanic eruptions

• Rise in sea levels

Why is studying past ocean acidification important?

• To predict future weather patterns

• To understand current ecosystem behavior

• To increase fish populations

• To decrease global temperatures

What can be predicted by understanding past ocean acidification events?

• The end of global warming

• The rise of new continents

• The extinction of all marine life

• Future seawater chemistry

What is the main cause of ocean acidification?

• Increased salt concentration

• Increased carbon dioxide in the atmosphere

• Decreased oxygen levels

• Decreased water temperature
