What are tiny Condensation A ______Warm front particles such as nuclei front is when salt, dust and warm air smoke that advances and water vapor goes over cold condenses on to air. form clouds? A ______front Occluded front A ______front Stationary front is caused by 3 is when a warm air masses air mass and cold air mass collide and doesn’t move

What happens An occluded What is a large Air mass when two front body of air with colder air similar masses force the properties as warmer air the earth’s mass up? surface above which it forms?

A ______Cold front What is a front? A boundary front is when where two cold air different air advances and masses meet forces warm up causing strong storms such as thunderstorms.
