Ocean Acidification

Ocean acidification begins with 

• pollution from ships
• carbon dioxide released from combustion
• dumping of waste from cities into the ocean

An example of a marine organism that needs calcium carbonate 

• a crab
• a shark
• an octopus

What do some marine creatures do with the carbonate ion?

• use it as a food source

• use it as a defense mechanism

• use it to build shells and exoskeletons

• use it to cool body temperatures

Burning carbon-based fossil fuels releases what gas into the atmosphere?

• acid gas

• chlorine gas

• oxygenated hydrogen

• carbon dioxide

How do scientists believe plant and animal life will be affected by increasing levels of acidity in the ocean?

• there will be more food for them to eat, making it easier to survive

• there will be less diversity in plants and animals, making survival more difficult

• the earth will correct the problem itself and the oceans' biodiversity will remain the same

• the plants and animals will adapt to the increasing acidity and continue to thrive in the oceans

The ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere.

• Coral Bleaching

• Ocean Acidification

• Smog

• Ozone Depletion

How can we help prevent ocean acidification?

• Use renewable resources

• Burn more fossil fuels

• Use your car more

• Dump waste into the ocean

As the ocean becomes more acidic, the pH of the water

• increases
• decreases
