    1. *When convection and winds cause air masses to move, they bump into one another.*The area where two air masses meet is called a front.*Most severe weather occurs near frontal boundaries. *
    2. *
    3. *
    4. *Cold, dense air is moving toward warm, less dense air.*The warm air is pushed up to cool and form clouds as the cooler air replaces it.*The air on the front side of the boundary line is warmer than the air on the back side of the boundary line.*These fronts are usually fast moving and bring stormy weather and heavy precipitation followed by clearing skies and higher pressure. *
    5. *
    6. *
    7. *Warm air is moving toward cold air.*The warm, less dense air slides over the cold, more dense air.*The air on the front side of the boundary line is cooler than the air on the back side of the boundary line.*These fronts usually move slowly and bring steady rain or snow over many days. *
    8. *Warm and cool air masses that are not strong enough to move one another*Sits still for a long period of time *
    9. *
    10. *These fronts occur when neither the cool nor warm air masses are strong enough to replace each other.*They tend to stay in an area for a long period of time, often bringing long periods of precipitation and clouds. *
    11. * Two cooler air masses meet and force a warm air mass aloft.* Brings cool temperatures and large amounts of rain or snow.* Followed by clear skies and drier air. *
    12. *
    13. *This is when a warm air mass is caught between two cold air masses.*The colder air mass moves under the warm air mass and pushes it up.*The colder air mass then moves forward until it meets a cold air mass that is warmer and less dense.*The colder air mass moves under this air mass and pushes it up.*Brings clear skies and drier air. *

    17. *The heating and cooling of water and land produces land breezes and sea breezes.*High pressure moves toward low pressure, pushing the warm air upward.*As warm air rises, cooler air moves in and replaces it. *
    18. *The Sun heats the water and land every day.*Land heats up rapidly, but cools off rapidly. *Desert*Water heats up slowly, but cools off slowly. *Swimming at night*The heat retained by the oceans is what keeps our planet insulated. *
    19. *
    20. *Weather is the atmospheric condition at a certain time and place.*Weather maps are used to show current weather conditions in an effort to predict future weather conditions.*You need to know what each symbol means and how to interpret them to forecast the weather. *
    21. *Air pressure is measured with a barometer in millibars.*Millibars are represented by connected lines of equal pressure. This is a lot like the topographic map lines.*The closer together the lines are, the faster the wind speed.*The farther apart the lines are, the slower the wind speed. *
    22. *
    23. *Cooler, dense air close to the surface of the Earth.*Surrounded by winds flowing in a clockwise direction.*Usually brings dry conditions and fair skies. *
    24. *
    25. *Warmer, less dense air above the Earth’s surface*Surrounded by winds moving in a counterclockwise direction.*Associated with the formation of storms. *
