How would conditions on Earth be different if its axis did not tilt? * A There would be no seasons.
B There would be no years.
C There would be no temperature
D The equator would not be as warm in winter.

If the earth didn't have a tilt, we wouldn't have seasons. Instead, the environment would be unchanging, and the temperature would vary upon latitude. Equatorial regions would be constantly hot and humid, and polar regions would always be cold. There would no variability to the climate as the year progresses.
