If Earth's axis had no tilt, would we still have seasons? Why or why not?
What will be an ideal response?
We would no longer have seasons, because the Sun's light would hit at the same angle all throughout the year, depending only on where you lived. The slight change in distance between Earth and the Sun during the year would not produce much of an effect.
