What are the four parts of the water cycle
Evaportaion, condensation, precipitaion, collection
Evaporation
water heats up and turns into a gas
Condensation
water vapor condenses to form clouds
Precipitation
water vapor becomes a liquid rain,snow
Collection
rain is collected into a body of water
What gasses make up the atmosphere
78 % Nitrogen and 21% Oxygen
Weather occurs in which layer of the atmosphere
Troposphere
How do we measure air pressure
Barometer
How do air masses move
High to low pressure
What are the four diffrent characteristics of air masses
Maritime tropical, Continental tropical, Maritime Polar, and Continental Polar
Maritime Tropical
warm and wet
Continental Tropical
dry and warm
Maritime Polar
wet and cold
Continental Polar
dry and cold
What is a front
a boundary between two air masses
What are the diffrent types of fronts?
Cold, warm, Stationary, Occluded
What happens in the cold front
cold air runs into slow warm air then cold air sinks and warm air pushes upward
What happens during a warm front
a fast moving warm air mass overtakes a slow moving cold air mass
What happens during a stationary front
cold and warm air meet but neither one can move each other
What happens during an Occluded front
warm air is caught between two cold air masses
What other aspects of our earth can influence the change in weather
Distance from the ocean, latitude, altitude
Latitude
distance from the equator
Altitude
higher locations are colder from ground level example mounatins
What color is the Letter H and what weather
cold and blue
What color is the low pressure system
red and warm
