Question

1. predict what the effect would be on earths seasons if the axis were tilted at 18.5 degrees instead of 23.5 degrees.

Explanation:

Earth's seasons are caused by the tilt of its axis. A smaller tilt (18.5 degrees instead of 23.5 degrees) would mean less extreme differences in solar - energy distribution throughout the year. The range of latitudes experiencing significant seasonal temperature changes would be reduced. Areas closer to the equator would still have relatively consistent climates, but regions that currently experience more pronounced seasons (like mid - latitudes) would have milder seasons. The difference between summer and winter temperatures would be less. Also, the length of days and nights would vary less throughout the year compared to the current 23.5 - degree tilt.

Answer:

If Earth's axis were tilted at 18.5 degrees instead of 23.5 degrees, the seasons would be less extreme. There would be smaller differences in temperature between summer and winter, and less variation in day - length throughout the year.
