1.
A dry, cold air mass would be called
Correct Answer
B. Continental polar
Explanation
A dry, cold air mass would be called "continental polar" because it originates over land (continental) and is characterized by its cold temperature (polar). This type of air mass typically forms in the polar regions and moves southward, bringing cold and dry weather conditions to the areas it affects.
2.
When a warm air mass and a cold air mass meet, but they push at each other and neither one can move, it is called a/an
Correct Answer
D. Stationary front
Explanation
A stationary front occurs when a warm air mass and a cold air mass meet but neither one can move, resulting in a boundary that remains stationary. This can happen when the forces pushing the air masses are balanced, preventing either one from advancing. As a result, the weather along a stationary front can be characterized by extended periods of precipitation and cloudy conditions.
3.
When a warm air mass is trapped between two cooler air masses, it is called a/an
Correct Answer
C. Occluded front
Explanation
An occluded front occurs when a fast-moving cold front overtakes a slower-moving warm front. As the cold front catches up to the warm front, it lifts the warm air mass off the ground. This lifting causes the warm air to cool and condense, leading to the formation of clouds and precipitation. The warm air is "occluded" or cut off from the ground as it is lifted and pushed upward between the two cooler air masses. This results in a complex weather pattern with a mixture of warm and cold air.
4.
The boundary between cold and warm air masses is called a/an
Correct Answer
B. Front
Explanation
A front is the boundary between two air masses with different temperature characteristics. Cold air masses are denser and tend to sink, while warm air masses are less dense and tend to rise. When these two air masses meet, they create a front. Fronts are often associated with changes in weather conditions, such as storms and precipitation. Therefore, the correct answer is front.
5.
When a cold air mass moves into a warm air mass, it will get colder and we will have severe weather. What type of front is this?
Correct Answer
B. Cold front
Explanation
When a cold air mass moves into a warm air mass, it creates a cold front. As the cold air displaces the warm air, it causes the warm air to rise rapidly, creating instability in the atmosphere. This rapid uplift of warm air leads to the formation of cumulonimbus clouds, which are associated with severe weather conditions such as thunderstorms, heavy rain, and sometimes even tornadoes. Therefore, the correct answer is cold front.
6.
When a warm air masses gently slide on top of a cold air mass, and you have drizzly rain and then beautiful sunny weather, what front is it?
Correct Answer
A. Warm front
Explanation
When a warm air mass gently slides on top of a cold air mass, it creates a warm front. This occurs when the warm air gradually replaces the cold air, leading to a gradual increase in temperature. The result is drizzly rain followed by beautiful sunny weather, as the warm air brings moisture and then clears the skies.
7.
A/an _____________ is a large body of air that has the same properties as the Earth's surface over which it develops and has the same density and moisture content.
Correct Answer
B. Air mass
Explanation
An air mass is a large body of air that develops over a specific area and has the same properties as the Earth's surface, including density and moisture content. This means that the air mass will have similar temperature, humidity, and stability characteristics as the surface it formed over. Air masses play a significant role in weather patterns and can influence the type of weather experienced in a particular region.
8.
What type of weather would a continental tropical air mass bring?
Correct Answer
C. Dry and warm weather
Explanation
A continental tropical air mass is formed over warm land areas, typically in tropical or subtropical regions. Since it originates from a warm region, it carries warm and dry air. As it moves, it brings this warm and dry weather to the areas it affects. Therefore, the correct answer is dry and warm weather.
9.
An air mass that formed over the ocean near the equator would probably be:
Correct Answer
B. Maritime tropical
Explanation
An air mass that forms over the ocean near the equator is likely to be maritime tropical. This is because the equatorial region is characterized by warm ocean temperatures and high humidity, which leads to the formation of warm and moist air masses. These air masses are known as maritime tropical air masses. They have high temperatures and high moisture content, making them warm and humid.
10.
A wet, cold air mass would be:
Correct Answer
B. Maritime polar
Explanation
A wet, cold air mass would be maritime polar. Maritime polar air masses form over cold ocean currents and bring cool, moist air to coastal regions. These air masses are typically associated with cloudy and damp weather conditions.
11.
Where would you find a tropical maritime air mass?
Correct Answer
A. Over the ocean near the equator
Explanation
A tropical maritime air mass is characterized by warm and moist air. The equator is known for its warm temperatures, and the ocean in this region provides a source of moisture. Therefore, it is likely to find a tropical maritime air mass over the ocean near the equator.
