front | where 2 or more air masses meet |
Air mass | hot or cold air |
Air pressure | The force of air in an object |
Precipitation | rain, sleet, snow, or hail |
Evaporation | liquid turns to gas |
Condensation | gas turns to liquid |
Run off | where water sleet or snow return to the ocean |
Cold front | created by cold air pushing warm air upwards brings most rain |
Hurricane | A major storm caused by heated water occur every year and get stronger |
Tornado | a natural disaster caused by hot air colliding with cold air happen in flat areas |
wind | air moving fast |
occluded fornt | 2 cold air push warm air up warm air causes little rain but last longest |
stationary front | cold air and warm air collide warm air does not go up |
warm front | cold air goes warm air comes brings less rain |
