Ocean Acidification and Its Effects

The video discusses the critical role of oceans as a food source and the threat posed by ocean acidification due to increased CO2 levels from human activities. It explains the pH scale, the chemical reactions leading to acidification, and the impact on marine life and food chains. The video emphasizes the need for reducing carbon footprints through renewable energy and personal lifestyle changes to mitigate these effects.

What is the primary concern when the ocean becomes more acidic?

• It can no longer support marine life.

• It becomes too salty.

• It becomes too warm.

• It loses its color.

How does the pH scale help us understand ocean acidification?

• It measures the depth of the ocean.

• It measures the temperature of the ocean.

• It indicates how acidic or basic a solution is.

• It shows the salinity of the ocean.

What chemical reaction occurs when CO2 is absorbed by the ocean?

• CO2 forms oxygen.

• CO2 forms carbonic acid.

• CO2 forms salt.

• CO2 forms hydrogen gas.

What happens to marine creatures' shells in more acidic water?

• They grow larger.

• They become stronger.

• They dissolve.

• They change color.

What is a potential consequence of ocean acidification on the food chain?

• It stabilizes the ecosystem.

• It disrupts the ocean's food chain.

• It enhances the growth of small creatures.

• It increases the number of predators.

What is the relationship between global warming and ocean acidification?

• Global warming increases the ocean's pH.

• They both contribute to making the ocean hazardous for sea life.

• Global warming reduces ocean acidification.

• They are unrelated.

What is one way to reduce the human carbon footprint?

• Adopt clean, renewable energy.

• Increase plastic usage.

• Use more fossil fuels.

• Cut down more trees.

Which of the following is a small lifestyle change to help combat climate change?

• Use reusable water bottles.

• Drive more frequently.

• Buy more packaged goods.

• Use disposable bags.

How can individuals contribute to reducing ocean acidification?

• By consuming more seafood.

• By ignoring the issue.

• By using energy-efficient products.

• By increasing their carbon footprint.

What is a benefit of using renewable energy?

• It increases pollution.

• It depletes natural resources.

• It reduces the human carbon footprint.

• It is more expensive than fossil fuels.
