3. Wind What is wind? The movement of air caused by differences in air pressure (temperature). The greater the pressure difference, the faster the wind blows! Wind is caused by the uneven heating of the Earth!

4. What causes wind? Uneven heating of Earth’s surface causes temperature differences which causes pressure differences ( warm LOW, cold HIGH)

5. The Coriolis Effect Is caused by Earth’s rotation. Objects are deflected in a curved path. Because the Earth is spinning objects do not move above it in a straight line.

6. Global and Local Winds Global winds that blow from west to east are called westerlies. Narrow belts of fast moving winds above Earth’s surface that affect weather and airplane travel are called jet streams. Local winds are produced by local geographic features.

7. Sea and Land Breezes

9. Sea Breeze

10. Land Breeze

11. Valley Breezes and Mountain Breezes

12. Valley Breezes and Mountain Breezes Valley Breezes Warm air from the valley moves upslope During the day Mountain Breezes Cool air descends from the mountains During the night

13. Valley Breeze

14. Mountain Breeze

15. Heat Transfer

16. What type of heat transfer is shown? Convection - movement of substance due to difference in density Radiation - from the sun

17. What type of heat transfer is shown? Conduction - energy is transferred from one molecule (or substance) to the next.

18. What type of heat transfer is shown? Radiation - energy is transferred through electromagnetic waves (infrared). Can go through space or matter

21. Greenhouse Effect The greenhouse effect is the process where the gases in the atmosphere absorb thermal energy and radiate it back to earth. Global warming is caused by the increase greenhouse gases being released into the atmosphere.

22. Evaporation Evaporation is the process of a liquid changing state to become a gas. It is occurs more quickly because of: The amount of sun’s energy How quickly the wind blows

23. Clouds What kind of weather does a cumulonimbus cloud bring or forecast?

24. Clouds What is a cloud? A cloud is a group of water droplets in the air. How is a cloud formed? When water vapor (gas) in the air cools it condenses. Water will condense (turn back into a liquid) on a dust particle in the atmosphere.
