Ocean Impact on Climate and Acidity

Fatima Pintu from the EAS Education Office explains the increasing levels of carbon dioxide in the atmosphere and its impact on oceans. The video discusses the role of oceans in absorbing heat and carbon dioxide, leading to ocean acidification. An experiment is demonstrated to show how increased carbon dioxide levels can make ocean water more acidic, affecting marine life and climate regulation.

What has been a significant change in the atmosphere since the Industrial Revolution?

• Decrease in oxygen levels

• Increase in nitrogen levels

• Increase in carbon dioxide levels

• Decrease in carbon dioxide levels

How do oceans help in regulating the Earth's climate?

• By reflecting sunlight

• By absorbing and distributing heat

• By absorbing sunlight

• By increasing atmospheric pressure

What percentage of human-produced carbon dioxide is absorbed by the oceans?

• 40-45%

• 25-30%

• 50-55%

• 10-15%

What is the process called when seawater becomes less alkaline due to carbon dioxide absorption?

• Ocean salinization

• Ocean acidification

• Ocean evaporation

• Ocean neutralization

Which tool is NOT used to measure changes in ocean water?

• Ships

• Telescopes

• Satellites

• Floats

What is the purpose of the red cabbage pH indicator in the experiment?

• To indicate chlorophyll content

• To indicate pH or acidity

• To measure salinity

• To measure temperature

What does the presence of lighter purple streaks in the water indicate?

• Increase in water temperature

• Decrease in water acidity

• Decrease in water salinity

• Increase in water acidity

What is the control sample in the experiment?

• The glass bell

• The red cabbage indicator

• The container without candles

• The container with candles

What could be a consequence of increased ocean acidity on marine life?

• Damage to coral skeletons

• Increased oxygen levels

• Improved fish population

• Enhanced growth of coral skeletons

How does increased ocean acidity affect climate change?

• It has no effect on CO2 absorption

• It reduces the ocean's ability to absorb CO2

• It enhances the ocean's ability to absorb CO2

• It increases the ocean's temperature
