1. Wind! MCAS Bootcamp:

2. Wind Caused by the sun. Caused by the sun. Air near the ground is heated. Air near the ground is heated. Warm air is less dense and rises up. Warm air is less dense and rises up. Cold air rushes in (wind) to take its place. Cold air rushes in (wind) to take its place.

3. Global Wind Patterns (Pg. 155-156) Areas closest to the equator are warmest because they receive the most direct sunlight. Differences in air temperature cause wind currents (Convection Cycles) Warm air from the equator moves toward the Earth’s poles; Cool air at the poles moves toward the equator.

6. Local Wind Patterns (pg. 157) Land heats up quickly and cools down quickly. Land heats up quickly and cools down quickly. Water heats up and cools down slowly. Water heats up and cools down slowly. Daytime: Air over warm land heats up and is replaced by cool ocean breezes. Daytime: Air over warm land heats up and is replaced by cool ocean breezes. Nighttime: Air over warm water rises up and is replaced by cool breezes from the land. Nighttime: Air over warm water rises up and is replaced by cool breezes from the land.

9. The Water Cycle Evaporation: Water is heated and changes from liquid to gas (water vapor) Evaporation: Water is heated and changes from liquid to gas (water vapor) Rivers, Lakes, Oceans, Puddles, Plants Rivers, Lakes, Oceans, Puddles, Plants Condensation: Water cools and forms back into liquid. Condensation: Water cools and forms back into liquid. Clouds, Fog, Dew Clouds, Fog, Dew Precipitation: Water is too heavy to remain in the air and falls back to Earth Precipitation: Water is too heavy to remain in the air and falls back to Earth Rain, Snow, Sleet, Hail Rain, Snow, Sleet, Hail

12. Earth’s Tilt=The Reason for Seasons During summer, the Earth is tilted toward the sun and receives more direct sunlight. During summer, the Earth is tilted toward the sun and receives more direct sunlight. During winter, the Earth is tilted away from the sun and receives less direct sunlight. During winter, the Earth is tilted away from the sun and receives less direct sunlight. During spring and fall, the Earth is not tilted toward or away from the sun. During spring and fall, the Earth is not tilted toward or away from the sun. Summer in the northern hemisphere is winter in the southern hemisphere, and vice-versa. Summer in the northern hemisphere is winter in the southern hemisphere, and vice-versa.

14. Climate—Year Round (NOT Weather, which is daily) Latitude—Further from the equator=colder climate Latitude—Further from the equator=colder climate (Less Direct Sunlight) (Less Direct Sunlight) Altitude—Higher above sea level = colder climate Altitude—Higher above sea level = colder climate (Less things to absorb sunlight) (Less things to absorb sunlight) Oceans—Cooler Summers and Warmer Winters Oceans—Cooler Summers and Warmer Winters (Because water takes longer to heat up and cool down.) (Because water takes longer to heat up and cool down.)
