The Earth is at __ during the Northern hemisphere winter (on or about January 3).

The Earth's ____ produces the continually changing daily pattern of day and night.

Urban heat islands result from the fact that metal, glass, concrete, and other construction materials reflect more insolation than do natural vegetation and soil.

When we measure air ______, we are measuring the vibrational (or kinetic) energy

of the air molecules.

Radiant energy from the Sun is called insolation.

into several helium nuclei.

Sunspots are the result of magnetic storms on the sun.

At any point along the circle of illumination, the Sun would be on the horizon.

If the speed of Earth's rotation increased 50 percent, the length of a year would not change.

However, each day would be shorter.

Seasons occur as Earth moves closer to -- and farther from -- the Sun during the course of the year.

The top of the atmosphere, also considered the outer boundary of Earth's energy system, is referred to as the ______.

The ______consists of billions of stars as well as our own solarsystem.

The Sun emits radiation composed only of visible light wavelength.

Temperature decreases at normal lapse rate within the ______.

For locations north of the Tropic of Cancer, the Sun's altitude reaches its annualmaximum

on the December solstice.

The height of the troposphere is about 9 kilometers (6 miles) at the equator.

Rainbows and mirages are examples of ______.

______is the molecule-to-molecule transfer of heat energy as it diffuses through a substance.

Surfaces with high albedo reflect more light than those with low albedo.
