Convection
JACKPOT
JACKPOT
Defined as the force of BALANCE or a stable situation where opposing forces cancel each other out.
EQUILIBRIUM
This front occurs when a warmer air mass replaces a cooler air mass.
What is a warm front?
Occurs when molecules in a liquid gain enough energy that the overcome attractions from other molecules.
What is evaporation?
When materials, like soil or rocks are moved by the wind or water.
What is deposition.
Energy flows from the suns layer in the convection zone.
What is the sun's role in convection?
This air mass is commonly associated with Equilibrium in weather.
What is cold occlusion?
This front occurs when a cooler air mass replaces a warmer air mass?
What is a cold front?
Process by which a solid transforms into a gas without passing through the liquid stage.
Sublimation
The breakdown of earth's rocks at the Earth's surface by the action of rain water or other extremes of temperature.
What is weathering?
Heat moves from areas of high temperature to areas of lower temperature.
What are the forces that cause convection?
This air mass is often associated with high pressure.
What is a cold air mass?
Water vapor is lighter than these to gases.
What is nitrogen and oxygen?
Jackpot
300 Points for your team.
The process of eroding or being eroded by wind, water, or other natural agents.
What is Erosion.
Convection causes the transfer of heat through materials that uses liquids and gas.
What are the effects of convection?
The density of these air molecules are spread apart.
What is a warm air mass.
The air cools at this rate as long as the humidity is not condensing.
What is 5.4 degrees Fahrenheit?
Occurs when molecules of a solid speed up enough so that the molecules can move past each other as a liquid.
What is melting?
A system of a whirling air mass of cool dry air that generally brings fair weather and light winds.
What is high pressure?
Is the outer most layer of the interior of the sun. It extends from a depth of 200,000 km up to the visible surface of the sun.
What is the convection zone?
Instability's role in the Equilibrium Model?
What is an unbalanced balance?
The air masses overtakes a warm front is cooler than the cool air ahead of the warm front causing the mass to plow under both air masses.
What is a cold occlusion?
Is the state in which an air parcel finds itself colder than the warm air around it?
What is Instability?
Is mass per unit volume. Density is the measure of how closely the molecules are packed together.
What is air density?
