A continental polar air mass moves into an area. Based on the characteristics of this type of air mass, which changes are most likely to happen in the area?(1 point)
A: The temperature will increase and humidity will increase
B: The temperature will decrease and humidity will decrease
C: The temperature will decrease and humidity will increase
D: The temperature will increase and humidity will decrease
The correct answer is B: The temperature will decrease and humidity will decrease.
Continental polar air masses are cold and dry. As they move into an area, they will bring cooler temperatures and lower humidity levels.
Which type of air mass forms over a cold ocean?
A: Continental polar
B: Maritime polar
C: Continental tropical
D: Maritime tropical
The correct answer is B: Maritime polar.
Maritime polar air masses form over cold oceans, such as the northern Atlantic or the Pacific off the coast of Canada and Alaska. These air masses are characterized by cool temperatures and high humidity. They typically bring cool and moist conditions when they move inland.
which type of air mass is most likely to bring hot, humid weather?
A: Maritime polar
B: Continental polar
C: Continental tropical
D: Maritime tropical
The correct answer is C: Continental tropical.
Continental tropical air masses are characterized by hot temperatures and high humidity. They form over tropical and subtropical regions, where the air is heated by the sun. When these air masses move into a new area, they are likely to bring hot and humid weather conditions.
Which is most likely to cause clouds to form in a previously clear sky?
A: An air mass sinks and becomes warmer
B: A warmer air mass moves into the area and rises
C: An air mass sinks and becomes colder
D: A colder air mass moves into the area and rises
The correct answer is B: A warmer air mass moves into the area and rises.
When a warmer air mass moves into an area, it is less dense than the surrounding air and tends to rise. As it rises, it cools and condenses, leading to the formation of clouds. This process is known as convection and is commonly associated with the development of clouds and precipitation.
A mass of extremely cold, dry air moves over the ocean. Which type of air mass does it most likely become?
A: Continental artic
B: maritime tropical
C: maritime polar
D: continental tropical
The correct answer is C: maritime polar.
When an extremely cold, dry air mass moves over the ocean, it tends to pick up moisture and increase in humidity. If the ocean is relatively cold, it will not warm up the air mass significantly. Therefore, the air mass is most likely to become a maritime polar air mass, characterized by cold temperatures and increased humidity due to interaction with the ocean.
