| How are winds named? | By the direction they're blowing |
| How do winds affect the oceans? | They create currents |
| Which wind belt goes over Lebanon and drives most of our weather? | Westerly Winds Belt |
| How does humidity affect the atmospheric pressure? | Less humid air=higher air pressure |
| How does temperature affect the atmospheric pressure? | Cold air= higher pressure |
| What creates wind? | When the cold air molecules they to go to the warm air molecule |
| How does altitude affect atmospheric pressure? | Higher you go, the lower the pressure is |
| Which air mass would form in the Gulf of Mexico? What would its properties be like? | Continental Tropical, warm and dry |
| Which summer air mass would form in the South Western US? What would its properties be like? | Maritime Tropical, warm and moist |
| What happens when 2 different air masses collide? | A thunderstorm is born |
| What causes storms? | When air masses collide |
| What is El Nino? | A warm surface current |
| Which storm covers the largest areas? | Hurricanes |
| When and where do the most hurricanes form? | Late summer and down in the tropics, mainly in the Atlantic Ocean |
| Different name for hurricane? | Typhoon |
| What's the driving force of a hurricane? | A warm surface layer of ocean water that evaporates, then condenses |
| What causes the hurricanes and other storms to spin? | The Coriolis Effect |
| What scale do we use to classify hurricanes? | Saffir-Simpson Scale |
| What is the deadliest part of a hurricane? | Storm Surge |
| What happens when the hurricane makes it to land? | It looses energy |
| What is the pressure and how is the air moving in the eye of the hurricane? | Low pressure and the air is sinking |
| What type of cloud forms a thunderstorm? | Cumulonimbus |
| What happens when a colder air mass hits a warmer air mass? | A front is born |
| Why doesn't the wind move in a straight line from high to low? | The Coriolis Affect |
| Why is sitting in a car safe during a lightning storm? | The current goes through the frame and and doesn't hurt you |
| How can you judge the distance to an approaching thunderstorm? | Count the seconds between the flash and the thunder (5 seconds=about a mile away) |

| What should you do during a thunderstorm? | Unplug electronics and stay away from running water |
| What storm can happen due to a thunderstorm? | Tornadoes |
| What scale do we use to measure tornadoes? | Fujita Scale |
| In case of a severe storm, what 3 things should you have on hand at your house? | Flashlights, extra food, a radio |
| What is causing most surface ocean currents to move? | Wind |
| Explain density currents. | Cold molecules sink because the density is higher creating a current |
