  1. Increased tourism revenue

  2. Decreased tourism revenue

  3. Improved water quality

  4. Enhanced coral growth
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ocean acidification can lead to decreased tourism revenue because it can damage or kill marine organisms, including those that are popular with tourists.

Multiple choice

What are some of the political impacts of ocean acidification?

  1. Increased international cooperation

  2. Decreased international cooperation

  3. Improved water quality

  4. Enhanced coral growth
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ocean acidification can lead to decreased international cooperation because it can create conflicts between countries over access to marine resources.

Multiple choice

What are the consequences of permafrost thaw?

  1. Release of greenhouse gases into the atmosphere

  2. Changes in plant and animal life

  3. Changes in the landscape

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Permafrost thaw can lead to the release of greenhouse gases into the atmosphere, changes in plant and animal life, and changes in the landscape.

Multiple choice

What are the potential consequences of permafrost thaw for the global climate system?

  1. Release of greenhouse gases into the atmosphere

  2. Changes in the Earth's temperature

  3. Changes in the Earth's climate

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Permafrost thaw can lead to the release of greenhouse gases into the atmosphere, changes in the Earth's temperature, and changes in the Earth's climate.

Multiple choice

How does increased CO2 in the atmosphere lead to ocean acidification?

  1. CO2 dissolves in seawater and forms carbonic acid

  2. CO2 reacts with calcium carbonate to form bicarbonate ions

  3. CO2 increases the temperature of the ocean, leading to acidification

  4. CO2 decreases the pH of the ocean directly
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When CO2 dissolves in seawater, it reacts with water molecules to form carbonic acid (H2CO3). This carbonic acid then dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3-), lowering the pH of the ocean and making it more acidic.

Multiple choice

How does ocean acidification affect coral reefs?

  1. It reduces the growth rate of corals and makes them more susceptible to disease

  2. It causes corals to bleach and die

  3. It dissolves the calcium carbonate skeletons of corals

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ocean acidification affects coral reefs in several ways. It reduces the growth rate of corals, makes them more susceptible to disease, causes them to bleach and die, and dissolves the calcium carbonate skeletons of corals.

Multiple choice

What is the potential impact of ocean acidification on the global food supply?

  1. It could lead to a decline in fish populations and reduced seafood availability

  2. It could affect the productivity of aquaculture, which is a major source of seafood

  3. It could disrupt marine ecosystems and food webs, leading to unpredictable consequences for food security

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ocean acidification has the potential to impact the global food supply in several ways. It could lead to a decline in fish populations and reduced seafood availability, affect the productivity of aquaculture, and disrupt marine ecosystems and food webs, leading to unpredictable consequences for food security.

Multiple choice

What is the term used to describe the increase in the Earth's average temperature due to human activities?

  1. Global Warming

  2. Climate Change

  3. Greenhouse Effect

  4. Carbon Footprint
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Global Warming refers to the long-term increase in the Earth's average temperature due to the accumulation of greenhouse gases in the atmosphere.

Multiple choice

Explanation

All of the above are potential risks of permafrost melting.

Multiple choice

What is the primary cause of sea level rise?

  1. Melting glaciers and ice sheets

  2. Thermal expansion of ocean water

  3. Increased precipitation

  4. Deforestation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary cause of sea level rise is the melting of glaciers and ice sheets, particularly in Greenland and Antarctica, due to rising global temperatures.
