Weather UNit Exam

What is the difference between weather and climate?

• Weather refers to short-term atmospheric conditions in a specific area, while climate refers to long-term patterns and trends of temperature, precipitation, and other atmospheric conditions in a region.

• Weather only refers to temperature, while climate refers to all atmospheric conditions

• Climate only refers to short-term patterns, while weather refers to long-term trends

• Weather and climate are the same thing

Explain the concept of air masses and how they influence weather patterns.

• Air masses are only found in the upper atmosphere and do not affect weather patterns.

• Air masses are small bodies of air with varying temperature, humidity, and pressure. They have no influence on weather patterns.

• Air masses are made up of only water vapor and have no impact on weather patterns.

• Air masses are large bodies of air with relatively uniform temperature, humidity, and pressure. They influence weather patterns by bringing their characteristics to the areas they move over.

What are the different types of fronts and how do they form?

• Tropical front, desert front, arctic front, and temperate front

• Morning front, afternoon front, evening front, and night front

• Sunny front, rainy front, snowy front, and foggy front

• Cold front, warm front, stationary front, and occluded front

How do high and low pressure systems affect weather conditions?

• High pressure systems bring fair weather and low pressure systems bring clouds and precipitation.

• High and low pressure systems have no impact on weather conditions

• High pressure systems bring clouds and precipitation

• Low pressure systems bring fair weather

Explain the relationship between humidity and precipitation.

• Precipitation has no relationship with humidity

• Humidity affects the likelihood of precipitation.

• Precipitation causes an increase in humidity

• Humidity decreases the likelihood of precipitation

Discuss the role of the jet stream in influencing weather patterns.

• It has no impact on weather patterns

• It is responsible for creating sunny weather

• It causes earthquakes and tsunamis

• It influences weather patterns by steering storms and determining the location of high and low-pressure systems.

What type of storm front is this? 

• warm front
• cold front
• stationary front
• occluded front

What does symbol # 3 mean?

• stationary front
• occluded front
• warm front
• cold front

A front is

• where warm air is cooling at earth's surface
• a line where hot and cold air are separating
• a line where two different air masses meet
• where cold air is rising and forming rain clouds

Which most likely produces clear, cool weather?

• zero air pressure
• stable air pressure
• a low pressure system
• a high pressure system
