  1. I think the way the Earth is tilted is what causes the different seasons.

  2. To the best of my knowledge, I believe that the four seasons are determined by the position of the sun and the tilt of the earth on its axis.

  3. I think that the 4 seasons are caused by the rotation of the earth, as the side of the earth get further from the sun, it gets cooler and as it rotates back towards the sun it gets warmer??

  4. I think the reason we have four seasons is becasuse of the way the earth is tilted and its relationship to the sun.

  5. The distance and position from the sun causes seasons. The Earth spins on an axis as it revolves around the sun. If a place is tilted away from the sun, it will be cooler if it is leaning toward the sun it will be warmer. So, where a place's location on the Earth is, in relation to the Sun, will determine what season it is.

  6. The tilt of the earth relevent to the sun causes the four seasons. The earth rotates on it's axis at a tilt. The equator is the horizontal line around the "sphere" of the earth that is always closest to the sun. In different seasons, different areas of the earth's surface, either above or below the equator, increase and decrease in distance from the sun. This creates seasons.

  7. The earth's tilt on its axis. Mainly, its the earth's tilt that causes the four seasons. As the earth slowly rocks back and forth during its revolution around the sun, it puts certain places slightly farther from the sun and get hit less directly by the sun's rays and vice versa.

  8. Because of the earth tilting, and the angle of the sun.

  9. The four seasons are caused by the tilt of the earth. The tilt determines how much sunlight hits the earth at any given point. In the winter the particular area recieves a less intense and less concentrated amount of sunlight. In the summer the sun is more directly overhead and the area experiencing summer will recieve a more concentrated and intense amount of sunlight. This is why the areas around the equator stay hot more, becuase they are tilited less than the areas of the polar reagions for example who recieve a more indirect light.

  10. As the earth rotates and orbits the sun, the tilt of the earth will vary pointing one hemisphere toword the sun for part of the year. When a hemisphere is closest to the sun there is summer and when it is tilted away, there is winter. spring and fall are transtions during which the tilt is more equil.
