Final answer:
The Earth's tilt on its axis affects the seasons by causing variations in the angle of the Sun's rays and the duration of daylight hours.
Step-by-step explanation:
The Earth's tilt on its axis is of great importance in regards to the seasons. The tilt causes the angle at which the Sun's rays hit different parts of the Earth to vary throughout the year. When one hemisphere is tilted towards the Sun, it receives more direct sunlight, resulting in summer. When the hemisphere is tilted away from the Sun, it receives less direct sunlight, resulting in winter. This tilt also leads to the changes in the length of daylight hours and the intensity of the Sun's rays, which affect the temperatures experienced during different seasons.
