Ocean Acidification

What ion neutralizes the increased acidity of the oceans?

• magnesium

• carbon dioxide

• nitrogen

• calcium carbonate

Increased ocean acidity causes which of the following to occur in oceanic fish.

• Slows the speed they are able to swim

• Increases their metabolism

• Increases the size they can grow to

• Decreases their ability to detect predators

Ocean acidification begins with 

• pollution from ships

• carbon dioxide released from combustion

• dumping of waste from cities into the ocean

According to this slide

• CO₂ is causing marine life to die by "poisoning' the water

• CO₂ is destroying sea shells

• CO₂ is formed from the combustion of Octane

This image demonstrates that

• There is a direct correlation with the atmospheric CO₂ and the CO₂ in seawater

• That pH of the ocean increases as the atmospheric CO₂ increases

• That there is no correlation between pH of the ocean and atmospheric CO₂

What happened to the pCO2 between 1989 and 2014?

• it increased by 50

• it decreased by 50

• it increased by 100

• it decreased by 150

As the pH decreases, what happens to the ocean?

• It becomes more acidic.

• It becomes more basic.

Which atmospheric gas is responsible for increasing the acidity of the ocean?

• Nitrogen

• Oxygen

• Carbon Dioxide

• Water Vapor

Very slight increases in the acidity of seawater __________  marine organisms that make shells.

• doesn't bother

• has no effect on 

• is unhealthy and stresses

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

• increases

• decreases
