PSC 50 Chap. 3

Latent heat is ________ during glacial melt.

absorbed.

Compared to land, bodies of water:

cool more slowly.

The region with the greatest difference between summer and winter average temperatures would be:

eastern Siberia.

Albedo:

is high for ice, snow, and thick clouds.

Sweating cools people because:

it utilizes evaporative cooling.

Greenhouse gases:

keep the earth at a comfortable temperature.

Water vapor is the primary carrier of:

latent heat.

The latent heat released during rainfall is ________ the latent heat released during snowfall.

less than.

Latent heat released during dew formation is ________ the latent heat required for water to freeze from its liquid state.

more than.

The radiation emitted by the earth is:

primarily absorbed by the atmosphere.

Why is the sky blue?

rayleigh scattering of solar radiation by air molecules.

The range of daily temperatures is ________ during cloudy conditions because ________.

reduced; clouds reduce both the incoming shortwave radiation and the outgoing longwave radiation.

Latent heat absorbed during evaporation of lake water is _______ the latent heat released during fog formation.

same as.

The atmosphere is a:

selective absorber.

Solar noon is typically not the warmest time of the day because:

surface temperature increases as long as the energy gained by the surface is greater than the energy lost.

The difference between Rayleigh scattering and Mie scattering is:

the wavelengths of the incoming radiation and the size of scattering particulates.

The ________ attempts to tell us what it "feels like" in cold, windy conditions.

wind chill index.

The planetary albedo of the earth:

30%.
