Question | Answer |
---|---|
weather | condition os the sky during a certain time including weather, air pressure, clouds, precipitation |
climate | long term avergae for weather over a long period of time |
water cycle | nonstop repeating pattern of water in different stages of matter |
evaporation | liquid changing to a gas |
condensation | gas changing to a liquid |
precipitation | gas changing to a liquid and falling from the atmosphere |
freezing | liquid changing to a solid |
melting | solid changing to a liquid |
ground water | araes on earths surface where water is stored including lakes, oceans, ponds, puddles |
transpiration | plants giving off water like evaporation to stay cool |
air pressure | messure of amount of air being exerted in an area of Earth's surface by the atmosphere |
high air pressure | air cools and becomes more dense it sinks towards earths surface causing increase in air pressure |
low air pressure | air warms and becomes less dense it rises away from Earths surface causing decrease in air pressure |
front | front edge of a boundary between two air masses typically named for the air mass moving into the area |
cold front | front edge of cold air mass occurs when a cold air mass moves into an area currently occupied by a warm air mass |
warm front | front edge of warm air mass occurs when warm air mass moves into an area currently occupied by a cold air mass |
stationary front | when a cold air mass is moving in one direction and runs into a warm air mass moving in the opposite direction |
occluded front | when a warm air mass moving into an area is followed immediatly by quickly moving cold air mass resulting in the warm air mass being pushed upwards |
air mass | large body of air in same range of tempreature and humidity |
isobar | line on map connecting all points of equal air pressure |
wind | air moving from high air pressure areas towards low pressure areas can be local or occur over large areas |
coriolis effect | mass such as the earth experiences a force acting perpendicular to the direction of motion and to the axis of rotation |
