100
the force caused by the weight of the air pushing on everything around it.
What is air pressure?
100
the circular pathway along which energy travels through a fluid.
What is a convection current?
100
narrow bands of moving ocean water
What are ocean currents?
100
the amount of water vapor in the air compared to the amount of water vapor the air can hold at that temperature.
What is relative humidity
100
a large body of air that has the same temperature and moisture throughout.
What is an air mass
200
an instrument used to measure air pressure
What is a barometer?
200
the transfer of heat energy through a fluid by moving particles.
What is convection?
200
Why did the wet thermometer show a greater dropin temperature?
What is evaporation.
200
a warm surface current that runs the wrong way across the Pacific Ocean
What is El Nino
200
a sharp boundary that forms when different air masses meet.
What is a front
300
the cool air that moves along the surface from the water onto land.
What is a sea breeze?
300
the transfer of heat energy between two materials that are incontact.
What is conduction?
300
the process by which a liquid changes to a gas
What is evaporation
300
global winds that blow constantly from east to west near the equator
What are the trade winds?
300
this forms when a cold, dense air mass moves into a warmer air mass.
What is a cold front?
400
cool air over the land moves over the water and lifts the warmer air as it replaces it.
What is a land breeze?
400
Why did the glitter rise and fall in the boiling water?
What is a convection current?
400
the change of state froma gas to a liquid.
What is condensation
400
the conditions of the atmosphere at a particular time and place.
What is weather
400
this forms when a warm air mass moves into a cold air mass.
What is warm front?
500
the amount of mass in a given volume of matter.
What is density?
500
Why does warm water rise to the surface?
What is a lower density than the surrounding water
500
the amount of water vapor in the air
What is humidity
500
When air is heated, the density of the air_____________
What is "decreases"
500
A falling barometer indicates a
What is a decrease in air pressure and a change in weather.
