  • Why does Mercury's temperature change drastically?
    Because Mercury has little to NO atmosphere to trap heat.

    On one of the outer arms of the Milky Way.
  • Why does the tilt of the Earth create seasons?
    Because the angle of sunlight varies on different parts of the Earth at different times of the year.
