When warm air from a large body of water moves quickly into a land area of cold air, we can expect _________ to occur where the two air masses meet.

• low humidity

• precipitation

• a gentle sea breeze

Typical United States weather patterns show the continental polar air mass moving south toward the Gulf of Mexico. Why does this air mass movement happen?

• Colder air masses move from north to south.

• Continental air masses always move in the direct of the nearest body of water.

• The polar air mass moves south to replace the rising maritime tropical air mass.

• The continental polar air mass is blocked in by maritime air masses on all sides.

A cold air mass from the north is blocked by a warmer air mass from the south. However, the air masses are not strong enough to push each other out of the way. As a result, the air masses remain over the place where they meet, resulting in prolonged cloudy and stormy weather.

Which weather map shows the weather conditions in the place where the air masses meet?

• 
•

As atmospheric gases warm, they will rise up higher in the atmosphere. The opposites is also true: As atmospheric gases cool down, the air will sink. This occurs over and over and air is heated and cooled. Which of these is the main factor that would contribute to this constant movement of the air?

• density

• mass

• matter

• electricity

What does this weather map symbol represent, and what type of weather can typically be expected when this symbol is shown?

• It represents a high front, which usually brings cooler temperatures and light rain.

• It represents a high pressure system, which usually brings clear skies and clear weather.

• It represents high temperatures, which usually means an increase in temperature following heavy rains.

• It represents heavy rain, which usually follows cool temperatures and is followed by high temperatures.

What does this weather map symbol represent, and what is its meaning?

• Moving front: the area between two air masses where is constantly in motion.

• Stationary front: the boundary between two air masses where no air is moving

• Cold front: the leading edge of a cold air mass is pushing against a warm air mass

• Warm front: the leading edge of a warm air mass is pushing in to replace a cold air mass
