1. What has happened to the Arctic Ocean during the past 40 years?
2. What feature of Earth would reflect the greatest amount of incoming sunlight?
3. Scientists have studied the changing temperatures in the Arctic during the past few decades. Which effect did the change in temperature have on the Arctic Ocean?
4. Why has the temperature of the Arctic Ocean changed during the last 40 years?
1. The Arctic Ocean has experienced significant warming during the past 40 years, leading to melting sea ice, loss of habitat for Arctic wildlife, and rising sea levels.
2. The feature of Earth that would reflect the greatest amount of incoming sunlight is ice and snow, due to their high albedo (reflectivity) properties.
3. The change in temperature in the Arctic has had various effects on the Arctic Ocean, including the shrinking of sea ice, changing ocean currents, and disruptions to marine ecosystems.
4. The temperature of the Arctic Ocean has changed during the last 40 years primarily due to the effects of climate change, including greenhouse gas emissions, deforestation, and industrial activities leading to the warming of the planet. The Arctic is particularly sensitive to these changes, resulting in rapid warming and melting of sea ice.
