The Coriolis Effect Defined: What in the World is it? Since the Earth is a globe, the speed of its rotation is fastest at the equator and slowest at the poles. When air leaves the poles its speed increases as it travels towards the equator. As a result the air veers and it doesn't go straight.
Warm Air Rises and Cold Air Falls- Why? Warm air is less dense so it rises up while cold air is more dense so it goes down.
What is the general pattern of wind currents on the globe? What is a convection current? Global circulation is driven by which two processes?
