• Because it is closest to the sun.

• Because it receives the most direct sunlight

• Because no clouds form here.

• Because it is far from the sun

_______is a measure of the reflective characteristics of the Earth's surface.

• Albedo Effect

• Greenhouse Effect

Which type of surface would have the highest albedo effect?

• Forest

• Snow

• Water

• Rock
