Atmosphere & Air Pressure
Mass divided by volume.
What is density?
At the beach, this substance heats up and cools off much more slowly than land.
What is water?
The state of the atmosphere at a given time and place.
What is weather?
The boundary that is formed when two air masses meet
What is a front?
Large stream of moving water that flows through the oceans.
What is a current?
a blanket of gases that surrounds Earth.
What is Earth's Atmosphere?
A change in the direction of moving air, water, or objects due to Earth's rotation.
What is the Coriolis effect?
The process of water changing into an invisible gas called water vapor.
What is evaporation?
The most likely weather result with an area of high pressure.
What is clear skies and sunny weather?
Driven by global winds, and affect water to a depth of a few hundred meters.
What are surface currents?
The force put on a given area by the weight of the air above it. This decreases as you go higher in altitude.
What is air pressure?
This type of local wind happens when the water is warmer than the land.
What is a land breeze?
It exists as a cool, colorless gas in Earth's atmosphere.
What is water vapor?
A large body of air that has temperature and moisture similar to the land or water over which it forms.
What is an air mass?
The direction of Coriolis effect on ocean currents in the Northern Hemisphere (opposite of how a hurricane rotates in the Northern Hemisphere).
What is clockwise?
The layer above the troposphere where planes fly long distances.
What is the stratosphere?
In this type of coastal wind, the air pressure is higher over the water than on the land.
What is a sea breeze?
The percentage of water vapor actually in the air, as opposed to the maximum amount of water vapor the air can hold.
What is relative humidity?
This front is represented on weather maps by semi-circles on a line.
What is a warm front?
The deep current that mixes all of Earth's ocean.
What is the Global Conveyer Belt?
Earth's weather occurs in this layer.
What is the troposphere?
Temperature differences between the equator and the poles produce giant convection currents in the atmosphere that moves air from the poles to the equator.
What are Hadley cells (or global winds)?
The part of the water cycle that requires the water molecules to give away heat energy.
What is condensation?
An air mass that is warm and wet.
What is a Maritime tropical air mass?
El Nino restricts this movement of deep cold water currents rising from the deep ocean to the surface.
What is upwelling?
