The conditions of the atmosphere at a given location for a short period of time
What is weather?
100
This causes most local weather condition changes
What is movement of air masses?
100
Low pressure systems usually bring this
What are clouds and unstable conditions?
100
The two most prevalent gases in our air
What is oxegen and nitrogen?
200
The three classes of rock(s)
What are sedimentary,metamorphic,and igneous?
200
The characteristic weather that prevails from season to season and year to year
What is climate?
200
The movement of air masses is determined by two things
What are prevailing winds and upper air currents?
200
This is the general movement of highs and lows across the United States
What is from east to west?
200
As the density of air decreases,its pressure
What is decreases?
300
They are most rocks that show characteristics that give clues to this
What are formation conditions?
300
The cause of weather
What is the uneven heating of Earth's surface?
300
Boundaries between air masses
What is a front?
300
This type of air mass is warm and humid
What is Maritime Tropical?
400
This model shows how types of rocks or rock material may betranspered from one type of rock to another
What is the rock cycle?
400
These form when air remains nearly stationary over a large section of Earth's surface and takes on the conditions of temperature and humidity from a location
What are air masses?
400
This is likely to occur at fronts
What is precipation?
400
Hazardous weather conditions
What are thunderstorms,tornadoes,hurricanes,ice storms,and blizzards?
400
Insturments used to measure air pressure
What is a barometer?
500
A rock that can float
What is pumice?
500
Weather conditions at a location are determined primarily by three things
What are temperature,humidity,and air pressure of air masses over that location?
500
These systems generally bring this
What is high-pressure?
500
This is crucial for humans to be able to prepare for and respond to hazardous weather conditions
