Air Pressure
As elevation increases, air pressure ___________.
Decreases
What is the name of water falling from clouds due to gravity?
What type of clouds look fluffy and are associated with fair weather?
Cumulus
What is an air mass?
An air mass is a large body of air with uniform temperature, humidity, and pressure
What is humidity?
Amount of water vapor in the air.
What happens to air when it moves from high pressure to low pressure?
It creates wind
What is the process called where plants release moisture into the air?
Transpiration
What kind of precipitation forms when rain freezes on its way to the ground?
Sleet
What is the difference between a warm front and a cold front?
A warm front brings warm air, while a cold front brings cold air, usually leading to thunderstorms.
What is the dew point?
The dew point is the temperature at which air becomes saturated with water vapor and condensation begins to form.
What type of weather is usually associated with low-pressure systems?
Stormy or Rainy Weather
What is required for condensing water vapor to form a cloud?
Cloud Nuclei
Which type of cloud is known for bringing thunderstorms?
Cumulonimbus
What kind of weather is associated with a stationary front?
It can lead to prolonged periods of rain or cloudy weather.
What is a person who studies weather and climate called?
Meteorologist
What kind of weather is usually associated with high-pressure systems?
Clear Skies and Sunny
What is fog, and how is it similar to clouds?
Fog is a collection of water droplets close to the ground, similar to clouds but at ground level.
What is the force that causes precipitation?
Gravity
What happens when a warm front meets a cold front?
The warmer air is forced to rise above the colder air, typically leading to cloud formation and precipitation, often in the form of rain.
What is a benefit to surface runoff?
Helps recharge are lakes, rivers, and streams
What tool do meteorologists use to measure air pressure?
Barometer
Why do hurricanes weaken when they move over land?
Hurricanes lose their energy source—warm ocean water.
What is an example of cloud nuclei?
Pollen, dust, sea salt, etc...
What are the characteristics of a Maritime Tropical air mass?
Warm/Moist
How does temperature affect the amount of moisture air can hold?
Warm air can hold more moisture than cold air. As air cools, the moisture it contains may condense into water droplets or ice crystals.
