Question

Increasing the tilt of Earth's axis would result in more extreme seasonal changes, with summers becoming warmer and winters becoming colder in the northern hemisphere, such as in the United States. This is because the change in tilt affects the angle at which sunlight hits the Earth's surface, which affects the amount of energy received by different regions at different times of the year.
