|
| When the Earth is tilted towards the Sun, what season is being experienced in the Northern Hemisphere and Southern Hemisphere? | Summer is experienced in the Northern Hemisphere and Winter in the Southern Hemisphere because the Northern Hemisphere is receiving direct sunlight when it is pointing in the direction of the sun and vice versa with the Southern Hemisphere. |
| What are two reasons that the Sun-Earth system creates seasons? | Because throughout the Revolution different sides of the Earth face the Sun at different times. (direct/indirect sunlight) This causes one area of the globe to be warm for a period of the time while on the other side it is cold for a period of time. |
