Coriolis Effect - GCSE Geography Definition

Reviewed by: Bridgette Barrett

Last updated

The Coriolis Effect is a crucial concept in GCSE Geography. It refers to the apparent deflection of moving objects, like air or ocean currents, due to Earth's rotation. As the Earth spins on its axis, different parts of the planet move at varying speeds. Movement is faster at the equator and slower at the poles. This difference causes pathways of moving air and water to curve rather than move in straight lines. In the Northern Hemisphere, the deflection is to the right, while it is to the left in the Southern Hemisphere. The Coriolis Effect significantly influences global wind patterns and ocean currents, playing a vital role in shaping the planet’s climate and weather systems.
