Earth orbits the sun on a tilted axis. Different
hemispheres face the sun at differenttimes. At any time during the summer or winter, one part of the planet is more exposed to the sun. This exposure
changes as Earth spins in its orbit.
Earth’s seasons happen because of the tilt of the Earth’s axis. This tilting is what gives
usthe four seasons of the year.
