You are presented with the question "What creates winter?" and the following answer choices: 
- Slowing the transfer of heat
 - ice expanding in rock openings
 - earth spinning on its axis
 - earth revolves around the sun
 - a hemisphere is tilted toward the sun
 - a hemisphere is tilted away from the sun
 - lack of moisture in the air
 - mechanical weathering

Now knowing that when a hemisphere is tilted away from the sun , that hemisphere receives less direct sunlight and because of this tilt, the northern hemisphere receives less direct sunlight (creating winter) while the southern hemisphere receives more direct sunlight (creating summer), choose the best answer.
