2. WIND: CAUSED BY UNEVEN HEATING OF THE EARTH’S SURFACE -UNEVEN HEATING CAUSES DIFFERENCES IN AIR PRESSURE TO DEVELOP -WIND BLOWS FROM AREAS OF HIGH PRESSURE TO AREAS OF LOW PRESSURE -WIND BLOWS FASTEST WHERE AIR PRESSURE CHANGES THE QUICKEST.

3. SEA BREEZES: -ON A HOT SUMMER DAY,THE LAND HEATS QUICKER THAN THE OCEAN CAUSING LOW PRESSURE OVER THE LAND. -THE RESULT IS A COOL BREEZE BLOWING IN OFF THE WATER BECAUSE THE WATER HAS THE HIGHER PRESSURE OCCUR DURING THE DAY

4. LAND BREEZES: OCCUR AT NIGHT -AT NIGHT LAND COOLS QUICKER THAN THE OCEAN -THE AIR OVER THE WATER IS WARMER THAN THE AIR OVER THE LAND -LOW PRESSURE DEVELOPS OVER THE WATER -BREEZE BLOWS FROM THE LAND TO THE WATER

5. ANEMOMETER: MEASURES WIND SPEED *TO MEASURE WINDS, YOU NEED WIND SPEED AND WIND DIRECTION* WIND VANE: -MEASURES WIND DIRECTION -IT IS BUILT TO POINT IN THE DIRECTION OF THE WIND *WINDS ARE NAMED BY THE DIRECTION FROM WHICH THEY COME

6. CORIOLIS EFFECT: -OCCURS BECAUSE THE EARTH SPINS -IN THE NORTHERN HEMISPHERE, WINDS CURVE TO THE RIGHT OF THEIR ORIGINAL PATH -IN THE SOUTHERN HEMISPHERE, WINDS CURVE TO THE LEFT OF THEIR ORIGINAL PATH -CAUSES OCEAN CURRENTS TO CURVE AS WELL. “SURFACE OCEAN CURRENTS”

9. *WATER MOLECULES COLLECT ON “CONDENSATION NUCLEI”, TINY PARTICLES OF DUST AND DIRT *CLOUDS FORM WHEN RISING AIR IS COOLED BELOW ITS DEW- POINT WHEN DROPLETS BECOME BIG ENOUGH, THEY FALL OUT OF THE SKY AS PRECIPITATION WHEN WE SEE A CLOUD WE ARE NOT LOOKING AT WATER VAPOR(GAS). GAS IS INVISIBLE

10. *AIR CAN RISE FOR A COUPLE OF REASONS 1) LOW DENSITY DUE TO HIGH TEMPERATURE AND/OR HUMIDITY 2) MOVING MASS OF AIR HITS A MOUNTAIN 3) IF COLD AIR AND WARM AIR CRASH TOGETHER, THE COOL AIR SQUEEZES UNDER THE WARM AIR AND FORCES THE WARM AIR TO RISE AND COOL

11. 1 ST ) THINK ABOUT A BICYCLE PUMP -IT TAKES ENERGY TO COMPRESS THE PUMP AND THAT ENERGY CHANGES TO HEAT AND MAKES THE PUMP WARM

12. 2 ND ) THE OPPOSITE OCCURS AS AIR RISES IN THE ATMOSPHERE -RISING AIR EXPANDS DUE TO DECREASING PRESSURE -JUST AS COMPRESSION WARMS A GAS, EXPANSION OF RISING AIR CAUSES IT TO BECOME COOLER

13. -CLOUD DROPLETS MUST JOIN TOGETHER TO BECOME LARGE ENOUGH TO FALL THROUGH THE ATMOSPHERE -MOST PRECIPITATION BEGINS AS SNOW HIGH IN THE ATMOSPHERE -ONCE SNOW MELTS IT CANNOT TURN BACK INTO SNOW
