Phase Change
In what phase of matter does molecules start to attract closer to each other, almost as if the molecules are touching each other?
Solid
This gas makes up about 78% of Earth’s atmosphere.
Nitrogen
This is the boundary where two air masses meet.
Front
What are the two types of air that are determined by temperature?
Warm or Cold Fronts
This gas released by burning fossil fuels is the main driver of climate change.
Carbon Dioxide
At what temperature does ice begin to melt.
1oC or 33oF (One degree more than freezing point which is 0oC)
This layer of the atmosphere is where weather happens.
Troposphere
This type of front brings thunderstorms and a quick drop in temperature.
Cold Front
What type of energy is stored in food and fuel.
Chemical Energy
This term describes the long‑term warming of Earth’s atmosphere.
Global Warming
Liquid and Gas
This term describes a stream of moving ocean water, like the Gulf Stream.
When high and low pressure systems are near each other the pressure difference produces what?
Wind
Coal, oil, and natural gas are all examples of this type of limited energy resource?
Nonrenewable Energy Source
These gases trap heat in Earth’s atmosphere.
Greenhouse Gases
At what temperature does water boil?
212oF or 100oC
This force caused by Earth’s rotation makes up a global winds curve.
Coriolis Effect
These large bodies of air have the same temperature and humidity throughout.
Air Masses
If ice is placed on a hot plate where is the energy being transferred?
From the Ice to the Plate
Scientists use these long cylinders of ice to study past climates.
Ice Cores
When a star reaches Nuclear Fusion what phase of matter produces the light we see?
Plasma
This term describes the amount of water vapor in the air.
Humidity
This global high‑speed river of air helps steer storms across North America.
Jet Stream
This type of heat transfer travels through empty space.
Radiation
This human activity is the largest source of greenhouse gas emissions.
