Answer 1

Step-by-step explanation:

Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth's axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis.
