2. WEATHER - DAILY CHANGES IN THE EARTH’S ATMOSPHERE CLIMATE - LONG-TERM, SYSTEMATIC CHANGES IN THE EARTH’S CLIMATE OF A MULTI-YEAR SCALE

3. TYPES OF AIR MASSES AIR MASSES ARE DEFINED BY THE REGION OF THE WORLD IN WHICH THEY COME FROM AND THEIR MOISTURE CONTENT

4. E CONTINENTAL ARCTIC - cA CONTINENTAL POLAR - cP MARITIME POLAR - mP CONTINENTAL TROPIC - cT MARITIME TROPIC - mT

5. E CONTINENTAL POLAR - cP *1

6. E MARITIME TROPIC - mT *1

7. E EARTH’S SEASONS ARE CREATED BY CHANGING AMOUNTS OF INSOLATION (INCOMING-SOLAR-RADIATION)

8. E WHICH IS CREATED BY THE TILT OF THE EARTH ON ITS AXIS (RELATIVE TO THE SUN)

12. E EQUINOX EQUINOX ARE DAYS WHERE THERE IS AN EQUAL AMOUNT OF DAY / NIGHT AND THE SUN IS DIRECTLY OVERHEAD ON THE EQUATOR AT NOON

13. E SOLSTICE SOLSTICE ARE EITHER THE LONGEST DAY OR LONGEST NIGHT OF THE YEAR. ON THESE DAYS THE SUN IS AT ITS HIGHEST OR LOWESTPOINT OF THE YEAR

14. E WINTER SOLSTICE – DEC. 21 ST SPRING EQUINOX – MAR 21 ST SUMMER SOLSTICE – JUNE 21 ST FALL EQUINOX – SEPT. 21 ST

16. E HOW THE EARTH MOVES… ROTATE ON ITS AXIS REVOLVE AROUND THE SUN TILT ON ITS AXIS

17. E HOW THE EARTH MOVES… ROTATES ONCE EVERY 24 HOURS REVOLVES ONCE CYCLE EVERY 365.25 DAYS TILTS CREATES SEASON IN THE NORTHERN HEMISPHERE

18. E EVIDENCE OF EARTH’S ROTATION FOUCAULT’S PENDULUM CIRCUMPOLAR MOTION CORIOLIS EFFECT

19. E FOUCAULT’S PENDULUM A FREELY SWINGLY OBJECT APPEARS TO CHANGE ITS POSITIONS OVER TIME *2

20. E CIRCUMPOLAR MOTION ALL STARS APPEAR TO MOVE IN CIRCLES AROUND THE NORTH STAR *2

21. E CIRCUMPOLAR MOTION SHOW CIRCUMPOLAR MOVIE

22. E CORIOLIS EFFECT WINDS CURVE TO THE RIGHT IN THE NORTHERN HEMISPEHERE *3

23. E WHAT CAUSES SEASONS SEASON ARE CREATED BY THE EARTH’S TILT NOT ITS POSITION TO THE SUN WINTER IN THE NORTHERN HEMISPHERE ACTUALLY HAPPENS WHEN WE ARE CLOSEST TO THE SUN

24. E WHAT CAUSES SEASONS (WINTER)(SUMMER) *4
