APES 9.5 - Global Climate Change Pt 2

Benjamin, Noah, and Nora are studying the effects of rising sea levels on marine ecosystems for their science project. What impact could they expect to observe?

• Expansion of marine ecosystems

• Decrease in marine ecosystems

• No impact on marine ecosystems

• Shift in marine ecosystems to terrestrial areas

Evelyn, Arjun, and Aria are studying the effects of global warming on the ocean. They are specifically interested in how the rising sea level might affect the photic zone. What do you think would happen?

• The photic zone would expand

• The photic zone would shrink

• The rising sea level would have no effect on the photic zone

• The photic zone would disappear

Noah, Maya, and Avery are studying marine life and they are curious to know what happens to the marine organisms that rely on sunlight, like coral reefs, as sea levels rise due to global warming?

• They adapt to deeper waters

• They migrate to colder waters

• They become extinct

• They remain unaffected

Michael, Avery, and Grace went on a field trip to a local aquarium. They learned about the effects of climate change on fish populations. According to their guide, why are fish populations declining due to climate change?

• Decreased oxygen levels in the water

• Increased oxygen levels in the water

• Loss of habitat

• No impact on fish populations

Mason, Emma, and Benjamin went on a fishing trip. They discussed the concept of maximum sustainable yield (MSY) of a fishery. What does it mean?

• The total number of fish in the fishery

• The number of fish that can be caught without causing collapse of the fishery

• The number of fish that can be caught without any impact on the fishery

• The number of fish that can be caught for commercial purposes

David, Henry, and Benjamin went on a school trip to the Arctic. They noticed that the polar regions seemed to be warming faster than their hometown. What could be the reason for this?

• There is a higher concentration of greenhouse gases in the polar regions

• The decreased albedo of ice in the polar regions

• The polar regions have increased land mass

• The polar regions have a lower specific heat of land

Benjamin, Daniel, and Aiden are studying climate change and they came across the term 'polar amplification'. They found out that it refers to:

• The process of ice melting in the polar regions

• The increased warming effect in the polar regions due to climate change

• The expansion of polar ecosystems

• The decrease in sea ice in the polar regions

David, Arjun, and Henry went on a school trip to the Arctic. They noticed that the ice and snow were melting faster than expected. How does the albedo of ice and snow contribute to this polar amplification?

• Ice and snow have low albedo, causing increased warming

• Ice and snow have high albedo, causing increased warming

• Water has low albedo, causing increased warming

• Water has high albedo, causing increased warming

Arjun, Jackson, and William are studying the effects of air pollution on the Arctic. They are particularly interested in understanding how air pollution affects the ice in polar regions. What could be a potential impact?

• It decreases the melting of ice

• It increases the albedo of ice

• It decreases the warming effect

• It decreases the reflectivity of ice

Maya, Abigail, and Emma are studying about the arctic ecosystem. They learned that arctic sea ice plays a crucial role in this ecosystem. Can you help them understand why arctic sea ice is important for the arctic ecosystem?

• It provides a habitat for algae

• It provides a resting place for seals

• It regulates the temperature of the region

• It prevents polar bears from hunting
