The angle of Earth’s tilt has changed throughout Earth’s history and is still changing today. If Earth’s tilt were to decrease from 23.5° to 20.2°, which of the following changes do you expect would occur? Changes between seasons would be less drastic. Years would become slightly longer than they are now. Summer at locations along the equator would be shorter. Earth would no longer experience seasonal changes.

Today, the Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun. But this tilt changes. During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees. Because this tilt changes, the seasons as we know them can become exaggerated.
