Exam 9: External Energy Fuels Weather and Climate

The subtropical jets play a more dominant role in weather than do the polar jets.

Greenhouse gases include __________________.

There are two main jet streams in both the Northern and Southern Hemispheres,

Which of the following has the lowest heat capacity?

The greenhouse effect results in ________________.

Glass is opaque to _________ radiation.

The polar jet stream flows from west to east,under the influence of the Earth's rotation,in ____________________.

The Sun's energy heats all parts of the Earth equally.

Ascending air at the equator and descending air around 30 ^$\circ$ N and S latitudes create semicircular air circulation routes known as ___________________.

The dew point temperature is the temperature at which air reaches 100% relative humidity,and thus water can condense from the air to form dew.

The energy released by condensing a given mass of water is the same as that absorbed by evaporating the same mass of water.

Jet streams are relatively narrow bands of high-velocity winds that flow from west to east at high altitudes.

The process of expanding air causes cooling,an adiabatic process where temperature changes without loss of heat from the air mass.

Deep-ocean currents are more important in the global exchange of heat than are atmospheric motions.

The amount of heat required to raise the temperature of a sample of water is referred to as the ________________.

The fraction of solar energy reflected back to space due to Earth's cloudiness or snow and ice cover is known as ______________.

The Coriolis effect is greatest at the equator and least at the poles.

Because of its fluctuations in abundance,CO₂ is the most important of the greenhouse gases.

Water has the highest heat capacity of all solids and liquids,except liquid ammonia.

A cooling air mass aloft sinks and compresses,becoming denser and warmer as it sinks.
