Lesson 6 Study Guide: Air Masses and Weather

A ______________ air mass will form over the oceans near the poles.

• continental polar

• continental tropical

• maritime polar

• maritime tropical

A __________________air mass will form over land near the equator.

• continental tropical

• continental polar

• maritime tropical

• maritime polar

An air mass that forms over the ocean near the equator is a ____________________ ____________________________ air mass.

• tropical continental

• polar continental

• arctic maritime

• tropical maritime

An air mass that forms over land near the poles is a ____________________________ ____________________________ air mass.

• polar continental

• tropical maritime

• equatorial continental

• arctic maritime

To predict what type of weather an air mass will create, meteorologist will:

• collect and analyze the temperature and humidity data from the region where the air mass originates.

• collect and analyze the wind speed and direction data from the region where the air mass originates.

• collect and analyze the pressure and precipitation data from the region where the air mass originates.

• collect and analyze the solar radiation and cloud cover data from the region where the air mass originates.

A ________ air mass will bring cooler temperatures.

• warm

• cold

• stationary

• occluded

A ________________________ air mass will bring warmer ________________________.

• A dry air mass will bring warmer temperatures.

• A cold air mass will bring warmer temperatures.

• A humid air mass will bring warmer temperatures.

• A warm air mass will bring warmer temperatures.

If a low- pressure system moves into an area causing an increase in the average wind speeds and precipitation and a decrease in temperature and atmospheric pressure, it will most likely cause what type of storm?

• A. Hurricane

• b. Thunderstorm

• c. Snowstorm

• d. Tornado

On a weather map, ______________________ are used to indicate a change in air pressure. When isobars are closer together on the map, they are showing that pressure is changing ______________________, or quickly.

• clouds; steadily

• fronts; slowly

• isobars; rapidly

• temperatures; gradually

When a region is experiencing a __________________________ front, weather conditions will likely stay the same for several days because the air masses are not moving.

• warm

• cold

• stationary

• occluded
