6. oneone WE-3 Science Court – Seasons Notes 1.The Earth is tilted on its axis (23 1/3 o ). 2.The Earth rotates (spins) once a day. 3.The Earth revolves around the sun once a year. 4.The sun’s rays strike the Earth directly in some areas an indirectly (with slanted rays) in other areas. 5.An area of the Earth may be tilted towards the sun, away from the sun or neither.

7. oneone WE-3 1.Why do you think that the rays of sunlight that do not strike the Earth directly, do not produce as much heat energy as the ones that do? 2.What about the angle causes a decrease in energy? DISCUSS IN GROUPS

10. oneone WE-3 RECAP The sun’s rays strike the equator almost directly. The angle at this point is close to 90 degrees. This angle provides the most heat energy. At smaller angles the sun’s energy is more spread out. Therefore there is less heat energy in a given region and lower temperatures. This happens at higher latitudes. It also occurs at dawn and dusk … and during the winter.
