Understanding the Albedo Effect

What is albedo?

• The measure of the amount of sunlight absorbed by a surface

• The measure of the reflectivity of a surface

• The measure of the heat emitted by a surface

• The measure of the color of a surface

Which of the following surfaces has the highest albedo?

• Fresh snow

• Grass

• Ocean water

• Desert sand

Explain how urbanization can impact the albedo effect.

• Urbanization increases albedo by adding more reflective surfaces like roads and buildings.

• Urbanization decreases albedo by replacing natural surfaces with darker materials.

• Urbanization has no impact on albedo.

• Urbanization increases albedo by planting more trees.

Which of the following statements best describes the relationship between albedo and climate change?

• Higher albedo contributes to global warming.

• Lower albedo contributes to global cooling.

• Higher albedo can help mitigate climate change by reflecting more sunlight.

• Albedo has no impact on climate change.

Discuss how melting ice caps can create a feedback loop affecting global temperatures.

• Melting ice caps increase albedo, leading to cooling.

• Melting ice caps decrease albedo, leading to further warming.

• Melting ice caps have no effect on global temperatures.

• Melting ice caps increase albedo, leading to warming.

Which of the following factors does NOT affect the albedo of a surface?

• Surface texture

• Surface color

• Surface temperature

• Surface moisture

How does the albedo effect influence the Earth's energy balance?

• By increasing the amount of solar energy absorbed by the Earth

• By decreasing the amount of solar energy absorbed by the Earth

• By reflecting solar energy back into space

• By trapping solar energy within the Earth's atmosphere

Evaluate the impact of cloud cover on the Earth's albedo.

• Clouds decrease albedo by absorbing sunlight.

• Clouds increase albedo by reflecting sunlight.

• Clouds have no impact on albedo.

• Clouds decrease albedo by trapping heat.

Which surface would likely have the lowest albedo?

• A forest

• A snow-covered field

• A sandy beach

• A dark asphalt road

Analyze how seasonal changes can affect the albedo of a region.

• Albedo remains constant throughout the year.

• Albedo increases in winter due to snow cover.

• Albedo decreases in winter due to snow cover.

• Albedo is higher in summer due to more sunlight.
