2. Density • The state or quality of being dense; compactness; closely set or crowded condition.

3. P - Atmosphere • A mixture of gases that surrounds a planet, such as Earth

4. P- Psychrometer Tool used to measure moisture or relative humidity of the air (atmosphere).

5. P- Anemometer A device for measuring wind speed.

6. P- ConvectionCurrent Circular movement caused by differences in density of air depending on its temperature.

7. P - Upwelling Process where water beneath the surface rises up to replace surface water pulled away by the wind.

8. P - Gyres Ring-like system of ocean currents rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

9. P- Gulf Stream Warm ocean current that flows North from the Gulf of Mexico, along the East coast of the United States. • The Sun heats up the water near the equator, and this water moves to the north.

10. P - Humidity Amount of water vapor in the air.

11. P – Prevailing Winds Wind that blows predominantly from a single general direction.

12. P- Air Mass A large body of air that has similar temperature and moisture properties throughout.

13. P – Weather Front the area where two air masses with different temperatures and densities collide, but do not mix.

14. P – Jet Stream • Narrow band of air that moves at high speeds caused by cold and warm air meeting.

15. P- Air Pressure The weight of the air pressing down on the Earth, the ocean, and on the air below causes air pressure.

16. P – Deep Water Current Currents high in density because of the cold temperature that make up 90 percent of the ocean.

17. P – Surface Current Currents low in density because of the warm temperature that make up 10 percent of the ocean.

18. P – Coriolis effect The rotation of the Earth causes an interesting phenomena on free moving objects on the Earth. Objects in the Northern Hemisphere are deflected to the right, while objects in the Southern Hemisphere are deflected to the left.

19. P - Hurricane • A tropical storm with high winds. It increases energy when coming in contact with warm water

28. C: At the Beach If you went to a beach and stood near the water, you would feel a breeze hitting you. What do you think causes that wind? Explain.

29. Exi T Reflection Write a 1-paragraph summary about today’s lesson. Make sure to use at least 5 vocabulary words that we have learned.

30. 1/23/12 Convection Current S- Explain the difference between groups and periods on the periodic table.

31. P Practice Group Discussion: When we were learning about the earth’s layers- we learned about convection currents.

32. P Practice These convection currents were located in the mantle. They move the mantle around to keep it hot. When it comes to convection currents in our atmosphere- the currents do the same thing! Heat always rises- because it is less dense- so the warm air forces the cool air and this pattern continues over and over.

33. P Practice Think about this: Why is it usually cooler and windy at the beach than it is a few miles inland?

34. P Practice 2. The farther the air moves away from the “heat source”, the cooler it gets. So it then sinks back down (cold air sinks because it is more dense) 1. The land warms the air above it and it rises. 3. The air above the ocean is cooler than the air above the land 4. Lastly, the cold air from above the ocean water moves in to take the place of the warm air that has risen.

35. A-Convection Box Demo • In your A section, write a descriptive paragraph of what you see. • Answer the following question as well: • What is the purpose of the candle? • Why does the smoke rise through only one chimney? • What is the heat source for convection currents in our actual atmosphere?

36. C Connections What would happen if the sun was to mysteriously vanish? What would our environment be like?

37. E Exit Reflect on what you learned today about climatic interactions. Try to use your vocabulary while reflecting on today’s lesson. ½ page

38. S 1/24/13 • What would happen if the sun was to mysteriously vanish? What would our environment be like? Air Masses

39. P What is an Air Mass? • Large pockets of moving air commonly form that are separate from the surrounding atmosphere. • Two common properties of air masses are moisture content and temperature. • Types of air masses in North America: • 1. Maritime tropical 2. Continental tropical • Maritime polar 4. Continental polar • 5. Continental Artic

40. Key Information*** • Question to ask yourself did the air mass form over land or water? • Helpful Clues: • Maritime: forms over the oceans-wet • Continental: forms over land- dry

41. A- Instructions for foldable • 1. Layer the 4 pieces of printer paper so that an inch is showing. • 2. Fold the other half of the paper over so you have 7 tabs. • 3. Staple the very top of the foldable. • 4. Label the foldable the following: Blue=Maritime Tropical Orange= Continental TropicalYellow=Continental Arctic Green= Maritime PolarRed= Continental Polar

42. Maritime Tropical: • Warm and humid, forms over a tropical ocean. • Gulf of Mexico/Atlantic (will then go over SE US) • Pacific (goes over West Coast) • Summer: showers/thunderstorms • Winter: heavy rain/snow

43. Maritime Polar • Cool, humid air masses form over • North Atlantic • North Pacific • Tend to affect west coast more than east coast • Bring rain, fog, and cooler temps.

44. Continental Tropical • Hot dry air • Forms over SW or Northern Mexico • Move NE bringing hot dry weather to Great Plains

45. Continental Polar • Bitter cold, dry • Form over Central and Northern Canada and Alaska (Arctic Circle) • Winter: brings clear, cold, dry air • Summer: brings milder temps, can mix with warmer air and forms storms

46. Continental Artic • Extremely cold temperatures and very little moisture. • These usually originate north of the Arctic Circle and are mostly a winter air mass

47. How air masses move • 1. Prevailing westerlies • 2. Jet streams • Push air masses west to east • Fronts: when two air masses meet the boundary is a front. • The less dense air mass floats on top of the other and storms tend to develop on frontal boundary.

48. C- Make sure you know the location of these regions and the type of weather conditions in each.

49. E • What type of air mass typically forms over San Antonio? How do you know?

50. S 1/25/13 • Draw a picture that represents convection currents. Use a real world example and make sure you label it. Air Masses cont
