In the regions close to large bodies of water, sea breezes are the result of

• air flowing towards the land because of persistent adiabatic heating

• air flowing towards the land because the land surface heats faster than the water surface

• air flowing towards the sea because of high evaporation rates on land

• air flowing towards the sea because the water surface heats faster than the land surface

Which of the following air masses would be capable of holding the most moisture?

• an air mass at 45ºF

• an air mass at 56ºF

• an air mass at 40ºF

• an air mass at 86ºF

Vapor pressure is

• the part of the atmospheric pressure attributed to water vapor

• the maximum amount of water vapor that can exist in the air at a given temperature

• the amount of water vapor in the air relative to the possible maximum at a given temperature

• the mass of water vapor in a given kilogram of air

This phase change for water requires energy to be put into the water

• freezing

• condensation

• evaporation

Relative humidity is expected to be lowest

• around midnight

• at sunrise

• in the afternoon

• at sunset

Surface winds that blow from the subtropical highs to the subpolar lows are called

• polar easterlies

• trade winds

• westerlies

• doldrums

In the region of the subtropical highs, we find

• warm and wet conditions, and the world’s great tropical rainforests

• strong surface winds

• the largest zone of water surpluses in the world

• the world’s arid and semi-arid desert regions

A surface low pressure system is defined as one in which air is

• diverging and descending

• diverging and ascending

• converging and ascending

• converging and descending

Upper air winds

• are generally faster than surface winds

• are generally slower than surface winds

• are greatly influenced by friction

• are unaffected by Coriolis force

Warmer air can ‘hold’ more water vapor that colder air

• true

• false
