Define the coriolis effect and describe how it influences objects or fluids in each hemisphere

The Coriolis effect is the rotation of the water as it flows especially down a drain. In the northern hemisphere, water flows counter clockwise. Southern hemisphere, clockwise. This effects the rotation of storms as well. 

The Coriolis effect causes fluids, like water or air, to curve as they across or above Earth's surface. In the northern hemisphere it makes all the tornadoes, toilet water, and hurricanes spin or twist counter clock wise and in the southern hemisphere it make all the tornadoes, toilet water, and hurricanes spin or twist clock wise.
