How does global warming alter the albedo of the Arctic? Select the two correct answers.
Melting sea ice to reveal darker water.
Replacing tundra with more rapid growth.
Changing migration patterns for sea life.
Melting glaciers to reveal darker soil.
The correct answers to the question "How does global warming alter the albedo of the Arctic?" are:
1. Melting sea ice to reveal darker water: As global warming contributes to the melting of sea ice in the Arctic, this exposes darker ocean water. Since the water has a lower albedo (reflectivity) than ice, it absorbs more heat from the sun, further enhancing the warming trend.
4. Melting glaciers to reveal darker soil: Global warming also affects glaciers in the Arctic, causing them to melt and reveal darker soil underneath. Similar to the melting sea ice, the darker soil has a lower albedo than the reflective ice surfaces, resulting in increased absorption of solar radiation and heat.
Selecting these two options demonstrates an understanding of how global warming impacts the albedo of the Arctic by altering the surface conditions and reflectivity.
