Lesson 5 Review

What is albedo?

• How reflective a surface is

• How non-reflective a surface is

If something has a high albedo, that means that it is

• very reflective

• not reflective

Dark asphalt on roads would have

• Low albedo

• High albedo

Things that have low albedos usually have high temperatures

• True

• False

Which part of our planet maintains its temperature the best? (has a more constant temperature without huge fluctuations)

• Oceans

• Land Masses

If a planet has a really really high albedo, the temperature of that planets surface will most likely be

• cold

• warm

• hot

How does deforestation affect Earth's albedo?

• Less trees = Less Albedo = Higher Temperature

• Less Trees = More Albedo = Lower Temperatures

• Less Trees = More Albedo = Higher Temperatures
