the ship is 30o west of its home port

If a clock on a ship indicates that it is 2:00 P.M. in its home port, while another clock on the ship indicates that it is 12:00 noon at the ship's present location, what is the difference in longitude between the ship's present position and its home port?

Temperatures increase with increasing altitude (going up) in what two atmospheric layers?

mainly visible light and infrared energy

The Sun produces which of the following?

the interaction of the solar wind and atmospheric gases.

The auroras (borealis and Australis) in the upper atmosphere are caused by:

poorly mixed; the influence of gravity which causes gases of different weight to separate into layers

The heterosphere is the layer of the atmosphere in which the gases are ________ because of __________.

time that the sun is directly overhead at the Tropic of Cancer (summer solstice)

The maximum number of daylight hours of the year in the N. Hemisphere are experienced during the:

the International Date Line.

absorbs most ultraviolet wavelengths.

The ozonosphere is critical to life because it:

was first made by Pythagoras, 580-500 B.C.

The realization that the Earth was a sphere

approximately 480 km (300 mi.) above Earth's surface.

The thermopause is located:

Earth's sphericity, which presents varied angles to parallel solar rays.

If we burn fossil fuels, which release carbon dioxide and warm the atmosphere, as the oceans warm they will release more carbon dioxide, which warms the atmosphere. This is an example of __________ feedback. If the increased atmospheric carbon dioxide causes increased plant growth which removes carbon dioxide and cools the atmosphere, this is an example of __________ feedback.
