Air Masses and Weather Fronts

Miss Summers explains air masses and fronts, detailing how air masses are classified by moisture and temperature, and how they form different types of fronts. The video covers cold, warm, stationary, and occluded fronts, describing their characteristics and the weather they produce. Students learn to identify air masses and understand the impact of fronts on weather patterns.

What is the primary factor that determines the characteristics of an air mass?

• The altitude at which it forms

• The time of year it forms

• The location where it forms

• The speed at which it moves

Which of the following is NOT a characteristic used to classify air masses?

• Location of formation

• Wind speed

• Temperature

• Moisture content

What does the letter 'c' in an air mass classification stand for?

• Cloudy

• Cold

• Coastal

• Continental

Which air mass is likely to form over a desert?

• Maritime polar

• Continental tropical

• Maritime tropical

• Continental polar

What type of weather is typically associated with a cold front?

• Clear skies and warm temperatures

• Gentle rains and mild temperatures

• Severe weather and a drop in temperature

• Prolonged periods of rain or snow

What symbol is used to represent a cold front on a weather map?

• Green line with squares

• Red line with semi-circles

• Blue line with triangles

• Purple line with mixed shapes

How does warm air behave in a warm front compared to a cold front?

• It remains stationary

• It slides over the cold air

• It descends quickly

• It rises rapidly

Which type of front is characterized by two air masses that do not move?

• Occluded front

• Stationary front

• Warm front

• Cold front

What happens during an occluded front?

• Cold air moves in and replaces warm air

• Warm air moves in and replaces cold air

• A cold front catches up to a warm front

• Two air masses meet and stop moving

What is the typical weather pattern after a warm front passes?

• Rapid temperature drop

• Prolonged rain or snow

• Severe thunderstorms

• Clear skies and warm temperatures
