• conduction

Multiple Choice

The measure of the reflectivity of a surface.

• reflection
• albedo

• absorbance
• refraction

Multiple Choice

A snow-covered mountain has a______ albedo than a dark-colored corn

field. Therefore, it will reflect ________solar energy than the field.

• Blank 1: more

  Blank 2: higher

• Blank 1: higher

  Blank 2: more

• Blank 1: water

  Blank 2: Sun

• Blank 1: less

  Blank 2: lowest

Multiple Choice

which will most likely absorb more solar energy, a field of light-colored crops or a forest of dark trees?

• The field, dark surfaces have a lower albedo and thus reflect less and absorb more solar energy.

• The field, light surfaces have a lower albedo and thus reflect less and absorb more solar energy.

• The forest, light surfaces have a lower albedo and thus reflect and absorb more solar energy.

• The forest, dark surfaces have a lower albedo and thus reflect less and absorb more solar energy.
