Earth's Insulator
What surrounds the Earth and protects it from solar radiation?
Atmosphere
What term describes the force exerted by air molecules?
Air pressure
What causes wind?
Differences in air pressure
What is a weather map?
A model showing weather conditions over a large area.
What is an air mass?
A large body of air with similar temperature and humidity.
What percentage of the atmosphere is nitrogen?
78%
How does altitude affect air pressure?
Air pressure decreases with higher altitude.
What is the Coriolis Effect?
The deflection of moving objects due to Earth's rotation.
What are isobars?
Lines joining places of the same air pressure.
Name two types of air masses.
Warm air masses and cold air masses.
Name one of the gases that make up 1% of the atmosphere
Argon
Methane
Carbon Dioxide
Ozone
What instrument is used to measure air pressure?
Barometer
How do winds deflect in the Southern Hemisphere?
They deflect to the left.
What do isotherms represent?
Lines joining places of the same temperature.
What happens when two different air masses meet?
They can create weather changes, such as precipitation.
FRONT
What is the function of the atmosphere?
To protect the planet and regulates temperature for life
Describe the difference between high and low pressure systems.
High pressure brings clear skies; low pressure brings clouds and precipitation.
Why do planetary winds curve?
Due to the Coriolis effect and differences in pressure.
How do weather maps help in forecasting?
They show patterns and conditions to predict future weather.
Describe a cold front.
A cold air mass pushes up warm air, causing storms.
Describe how the atmosphere contributes to weather.
It interacts with air, water, and energy to produce weather patterns.
How do pressure systems influence weather patterns?
They affect temperature, precipitation, and wind.
How does the Earth's rotation affect wind patterns?
It causes winds to curve instead of blowing in straight lines.
What information can you get from a weather app?
Temperature, atmospheric conditions, and weather maps.
What is an occluded front?
A warm air mass caught between two cold air masses.
