Atmosphere Basics
This gas makes up most of Earth’s atmosphere.
What is nitrogen?
This type of heat transfer occurs through direct contact.
What is conduction?
Differences in air pressure are caused by this.
What is uneven heating?
Air masses are classified based on these two properties.
What are temperature and humidity?
This front is shown by blue triangles on one side of a line.
What is a cold front?
This atmospheric layer is where weather occurs.
What is the troposphere?
Land heats and cools _____ than water.
What is faster?
Caused by the Earth’s rotation, which curves moving air and water.
What is the Coriolis effect?
High pressure systems are usually associated with these conditions.
What is clear/sunny weather?
This type of front forms when a cold front overtakes a warm front.
What is an occluded front?
This form of oxygen absorbs most harmful UV radiation.
What is ozone (O3)?
This process transfers heat through the movement of currents like air or water.
What is convection?
These circulation cells move warm air toward the poles and cool air toward the equator.
What are Hadley Cells?
Air masses and wind generally move:
Along a front, this type of air is forced upward.
Climate differs from weather because climate describes conditions over:
What is many years/long periods of time?
This natural effect keeps Earth warm enough to support life.
What is the greenhouse effect?
The movement of warm air rising and cool air sinking is called:
What is convection?
What are warm and humid conditions?
A fast-moving cold front usually brings this type of precipitation.
What is heavy precipitation for a short period of time?
This boundary separates the troposphere from the stratosphere.
What is the tropopause?
Heat travels through electromagnetic waves.
What is radiation?
These winds move west to east along Earth's surface.
What are westerlies?
Low pressure systems are commonly associated with these conditions.
What are clouds and stormy weather?
This type of front occurs when the boundary between air masses does not move.
What is a stationary front?
