What are the primary ways that heat can be transferred?
Conduction, Convection, and Radiation
A fluid can be classified as:
either liquids or gasses.
What type of fluids have a lower thermal energy, which move or stay closer to the ground?
Cold fluids
What type of fluids have a higher thermal energy, which move or stay aloft or higher up?
Warm fluids
What is the area where cold and warm fluids collide or meet is known as?
Front
What are the two characteristics of air masses?
Temperature and humidity
What is an air mass that is dry and forms over land?
Continental air mass
What is an air mass that forms over the polar regions and is cold?
Polar air mass
What is an air mass that forms over the tropics and is warm?
Tropical air mass
What is an air mass that is wet and forms over water?
Maritime air mass
What forms when two different large air masses meet and usually bring changes in the weather?
Fronts
What type of front is made of cold, dense air?
Cold front
What is the front that brings rain, snow, thunderstorms and sometimes tornadoes, where the precipitation usually does not last very long?
Cold front
What is the front that forms when two air masses meet and neither one takes over?
Stationary front
What type of front often causes many cloudy days to occur in a row?
Stationary front
What type of front is formed when a large mass of warm air takes over the cooler air mass?
Warm front
What type of front usually produces rain, fog, or snow that is light but steady?
Warm front
What type of front develops when two cool air masses merge, forcing the warm air to rise and become trapped that usually brings wind and precipitation?
Occluded front
What type of pressure system usually indicates calm, clear weather?
High pressure
What weather can be expected as the cold front passes through an area?
Winds become gusty; sudden drop in temperature, heavy rain, sometimes with hail, thunder, and lightning.
