Google Expedition: Ocean Acidification

In chemistry,what is the scale used to specify the acidity or basicity in a water-based solution?

• pH

• acid level

• TA

• Kg

What is the typical pH of an acid?

• higher pH, >7

• 25 km

• lower pH, < 7

• 110 ppm

What is the typical pH of a base?

• higher pH, >7

• 25 km

• lower pH, < 7

• 110 ppm

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

• acid gas

• chlorine gas

• oxygenated hydrogen

• carbon dioxide

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

• it becomes more acidic

• it becomes more basic

• it becomes healthier to drink

• it turns into coal

The variety of plant and animal life in the world or in a particular habitat is called ____________________.

• fossil fuels

• biodiversity

• ecosystem

• climate change

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

Which of the following is not a way that carbon dioxide from the atmosphere end up in rivers and oceans?

• acid rain

• carbon cycle

• ocean uptake

• decaying fish

All carbon dioxide gas found in the ocean is there because humans are causing pollution from burning fossil fuels.

• True

• False

Humans can do very little to stop the decreasing pH levels of the world's oceans.

• True

• False
