Unit test Weather

What must the relative humidity be if it is foggy outside?

• 0%

• 1%

• 100%

• 99%

Wind is an example of

• Precipitation

• Convection

• Condensation

• Radiation

What happens to the air pressure as you go higher in altitude?

• It increases

• It decreases

• It remains steady

• It changes randomly

When the dew point temperature is close to the air temperature, it means that

• The air is very dry

• The air is very humid

• The air is very cold

• The air is very windy

The process of convection transfers heat energy:

• from high altitudes to low altitudes.

• From humid areas to dry areas

• From cold areas to warm areas

• From warm areas to cold areas

Heat energy in the atmosphere always moves

• From cloudy to clear areas

• From a low pressure to Hugh pressure regions

• From high temperature areas to low temperature areas

• From low temperature areas to high temperature areas

Wind is caused by:

• The earths tilt

• The movement of earth through space

• temperature and pressure differences in the atmosphere

• The pull of the moons gravity

Which term is a measure of the amount of moisture in the air?

• Precipitation

• Humidity

• Heat

• Pressure

When a mass of air is cooling, what will happen when the air temperature reaches the dew point?

• The skies will clear up

• Puddles of water will evaporate.

• It will always give some kind of weather

• Water vapor in the air will begin to condense

A boundary between two air masses with different temperature and moisture characteristics is

• A tornado

• A front

• A temperature inversion

• A hurricane
