• Earth's temperature has always been warmer than the present

• Earth's temperature has always been colder than the present

• Earth's temperature has changed randomly throughout history

Changes in eccentricity will have what effect on the global temperature?

• Determines which hemisphere has stronger seasons from eccentricity

• More gives Earth stronger seasons

  (warmer summer, colder winter)

• Oval gives one hemisphere stronger seasons (the other is more mild)

• Greenhouse gases have no effect on the temperature

• Greenhouse gases today are lower than they have been in the past

• we don't have any data of the temperature or gases from thousands of years ago

How does the ocean become more acidic?

• The ocean absorbs more carbon dioxide released by the burning of fossil fuels

• Boats are dumping toxic waste into the ocean

• The fish are not able to neutralize the acid in the ocean

• The ocean is actually becoming more basic

In the ocean acidification lab, what happened?

• We exhaled carbon dioxide into the water, the indicator turned BLUE, showing that the pH INCREASED

• We exhaled carbon dioxide into the water, the indicator turned YELLOW, showing that the pH DECREASED

• The water bubbled because of the presence of acid, turning the water blue

• We removed the oxygen in the water, causing it to become more acidic

What happens to the ocean ecosystem when the pH level decreases?

• The plankton and krill become damaged, disrupting a major food source

• The blood chemistry of the predators is affected

• The producers in the ocean increase
