- This is the rotating of the Earth towards the East
- Speed of rotation varies at different latitudes
- Forces moving objects on Earth to follow curved paths
- In the Northern hemisphere, they follow path right of intended course
- In the Southern hemisphere, they follow path left of intended course
- Has great effect on atmospheric circulation and ocean currents/tides
- In Northern hemisphere, most ocean basins have a circular current flow (gyre) rotating in clockwise direction
- In Southern hemisphere, ocean gyres rotate in anti-clockwise direction
