Reading 1 Federalism What is federalism? Federalism is a system of government in which power is distributed or diffused between a central government and smaller political units. In the United States, there are three basic levels of government: federal, state and local.
The large majority of the tornadoes in the northern hemisphere spin counterclockwise (cyclonically), but about 1 in 100 tornadoes spin clockwise. Actually, it has little to do with being in the northern hemisphere, as tornadoes do not last long enough for the effects of Coriolis to impact it.
The Coriolis effect helps explain the paths of winds in the atmosphere. In the Southern Hemisphere, winds pass from high-pressure systems to low-pressure systems on the left. This makes storms, such as Cyclone Ingrid, storming across northern Australia above, appear to swirl in a clockwise direction.
