Climate Change: Albedo

APES-IB2V1L

Glaciers and cloud cover increase albedo and thus are helping to slow global warming.

Of the following, which describes albedo?

A

Albedo is the ability of frozen and gaseous water to absorb solar energy.

B

Albedo is the ability of water to absorb large amounts of heat before its temperature changes.

C

Albedo is the reflectivity of a surface. Since ice and clouds have higher albedo than the oceans and land, they help reflect the suns energy back into space.

D

Albedo is the process by which the hydrogen bonds in water are broken. This absorbs energy and weakens sunlight.

E

Albedo is the process of ozone formation. The oxygen atoms in the water break off when sunlight hits them and they recombine to form ozone. This is and endothermic reaction, thus cooling the Earth.
