Earth Science

Confusing Rotation and Revolution

Saying rotation causes the seasons, or that one revolution makes a day.

Quick check

Why students make it

Both words describe Earth turning in space and sound alike, so their effects get swapped.

The rule done right

Rotation is Earth spinning on its axis, one turn per day, which causes day and night. Revolution is Earth orbiting the Sun, one trip per year, which together with the axial tilt causes the seasons.
