• both the angle of incidence and angle of inclination

Suppose that all the trees in a region are cut down, exposing dark soil. Assuming no vegetation grows back, how will the albedo of this region change?

• There will be no change in the albedo.

• Albedo will increase in summer and in winter.

• Albedo will decrease in summer and in winter.

• Albedo will decrease in summer and increase in winter.
