In summer, humid regions typically have ____ daily temperature ranges and ____ maximum temperatures than drier regions.
In the afternoon between 2 and 5 pm
In most areas, the warmest time of the day about 5 feet above the ground occurs:
Incoming solar radiation
In meteorology, the word insolation refers to:
Colder; warmer

In July, at middle latitudes in the Northern Hemisphere, the day is ____ long and is ____ with each passing day.
More than 12 hours; getting shorter
Ideal conditions for a strong radiation inversion are:
Clear, calm, dry, winter night

During an equinox,
The sun is directly above the equator, 0 degrees latitude

Near sunrise
At the North Pole the sun will rise above the horizon on ____ and set below the horizon on ____.

An important reason for the large daily temperature range over deserts is that:
There is little water vapor in the air to absorb and re-radiate infrared radiation
Although the polar regions radiate away more heat energy than they receive by insolation in the course of a year, they are prevented from becoming progressively colder each year by the:
Circulation of heat by the atmosphere and oceans
