Explanation:
Answer:
The revolution of the earth around the sun and the tilt of the earth's axis cause the changing of the seasons.
Explanation:
The Earth's rotation causes day and night, while its revolution causes seasons. This happens due to how the rotation exposes different parts of the Earth to the sun, and how the tilt of the Earth's axis during revolution causes varying sunlight exposure.
The rotation of Earth on its axis causes day and night. This astronomical phenomenon happens because as the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night. On the other hand, the revolution of the Earth around the sun causes the seasons. As the Earth orbits the Sun, the tilt of our planet's axis causes different parts of the Earth to receive varying degrees of sunlight throughout the year, which results in the changes in weather conditions we know as seasons.
