Weather factors include

Weather factors include

two of the above

The dew point is the temperature at which

all of the above (dew forms on surfaces, water vapor starts to condense, relative humidity is 100 percent.)

Relative humidity may decrease if

air temperature decreases.

Which type of cloud forms at high altitudes?

cirrocumulus

Which type of cloud forms when strong air currents carry warm air upward?

cumulus

The type of fog that forms when cool air moves over a warm lake is called

steam fog.

Rain that passes through a layer of freezing air near the ground becomes

sleet.

Which of the following decreases with an increase in altitude?

air pressure

You are in a moist forest, thick with tall coniferous trees. Which biome are you probably in?

humid subtropical

Which appear thin and wispy?

Cirrus

The sun is at its furthest north at

summer solstice

In which layer of the atmosphere does all weather take place?

Troposphere

Which of the following is a measure of how fast atoms in a material are moving?

temperature

Thunderstorms form when

the ground is warm and updrafts form

Which of the following adds oxygen to the atmosphere?

photosynthesis

What features does an air mass have nearly identical throughout?

temperature and humidity

Which weather phenomena is the most deadly per year?

heat wave

If the readings on your barometer fall,

storm clouds are probably on the way

Outside one morning the plants are coated with water but it didn't rain. The wetness is because

an inversion caused water to condense on the plants.

Carbon dioxide levels in the atmosphere

have been rising at least since 1958

A warm front occurs when

a warm air mass slides over a cold air mass

A cold front in winter will produce

cold temperatures but clear or slightly cloudy skies

After a cold front passes, the cold air mass is over you and you can expect

cold weather and clear or partly cloudy skies

An occluded forms around what feature?

low pressure system

Two air masses meet at what?

a front

Air masses usually do not form in the temperate zones because

the area is not hot or cold enough to affect the air.

Which directions do air masses tend to flow?

warm toward the poles; cold toward the equator

What happens when a warm air mass and a cold air mass meet?

the denser air mass goes beneath the less dense air mass

The strongest winds form when

the temperature difference between two air masses is very high.

Rising air creates

low pressure
