Final answer:
The tilt of Earth's axis is important in determining the seasons and climate on Earth.
Step-by-step explanation:
The Importance of Earth's Tilted Axis
Earth's axis is tilted at an angle of approximately 23.5 degrees. This tilt is crucial in determining the seasons on Earth. The tilt causes variations in the angle at which sunlight reaches different parts of the planet. In turn, this leads to variations in climate, temperature, and the length of daylight throughout the year.
If Earth's axis were not tilted, the seasons would not exist as we know them. There would be no summer, winter, spring, or fall. Instead, the climate would be relatively constant throughout the year, with minimal variations in temperature and day length.
