HW Review high high low

HW Review low high Durham Raleigh barometer A big thunderstorm is over Raleigh. The air pressure would be _____. Nearby in Durham the skies are clear and the air pressure is _______. Since wind moves from areas of high to low pressure, wind would be coming from ___________ and going to ___________. If the differences in pressure are really big, the winds could even be really fast! We can measure the differences in air pressure by using a ______________. low high Durham Raleigh barometer

Fronts collide boundary front weather What happens when air masses meet? Air masses _____________ (or crash into each other) very easily. The ________________ between two air masses is called a ___________. Many ______________ changes can happen here! Draw a line on the map where a front would be found. collide boundary front weather

Study Jams! What are the different types of fronts, and what types of weather do they cause?

clouds & some precipitation Types of Fronts under rises wind stops top bottom heavy rain, thunder, cold air, & wind drizzle, clear skies, & warm air clouds & some precipitation

Independent Practice cold stationary warm stationary cold  ________________ Which front has a cold air mass forcing itself underneath a warm air mass? _________________ Which front has two air masses that meet but stay stuck facing each other? _________________ Which front has a warm air mass rising up gently over a cold air mass? _________________ Which front causes many days of clouds and precipitation due to two air masses staying stuck together and neither one moving on top of the other? _________________ Which front that causes violent thunderstorms to form? stationary warm stationary cold

Independent Practice cold air rushing under warm air warm air slowly pushing into and rising over cold air warm and cold air meeting and not moving
