As the temperature of a gas increases, what will also increase?
gas's volume
100
TRUE OR FALSE: Atmospheric pressure will change as a front moves across an area.
TRUE
100
What does a barometer do?
measures atmospheric pressure
100
Name the 4 types of fronts?
Warm, Cold, Occluded, and Stationary
100
Name the 4 types of precipitation?
hail, rain, snow, and sleet
200
Which best describes what causes wind?
difference of high pressure and low pressure in the atmosphere.
200
Dense air pressing down on the Earth's surface will likely create what?
high pressure
200
What happens when the barometer is rising?
High pressure zones
200
What is a cold front?
colder air mass moves in behind a warmer air mass. It plunges beneath it and forces the warm air mass up into the atmosphere.
200
Describe evaporation.
a change of phase in which the liquid phase of a substance is converted to a gaseous phase.
300
Cold air is _____ air
heavier/denser
300
TRUE OR FALSE: When air heats up, its volume increases but its mass stays exactly the same.
TRUE
300
What happens when the barometer is falling?
Low pressure zones.
300
What happens in a warm front?
A warmer air mass moves in behind a colder air mass. It crawls over the cold air mass and rises into the atmosphere.
300
What types of weather occurs in high pressure zones?
sunny, a bit of a breeze, some clouds
400
Warm air ____________
rises
400
What direction is the cold air front moving?
South/Southeast
400
What type of weather occurs in low pressure zones?
thunderstorms, bad weather, different types of precipitation.
400
What is condensation?
a change of phase in which the gaseous phase of a substance is converted to a liquid phase.
400
What factors are necessary for precipitation to form along fronts?
a difference in density between warm and cold air masses, an upper atmosphere that has temperatures lower than the air in the rising warm air mass, and condensation of water vapor in the rising warm air mass.
500
Which area will have the strongest winds?
The low pressure along the south/east coast.
500
What is the unit of measure for a barometer?
hectopascals
