Why do we rotate along with the earth's rotation?

Friction again. Suppose the atmosphere was not rotating at all. The word hurricane doesn't begin the describe what the resulting 1000 mile/hour wind would do. The Earth would quickly spin the lower atmosphere up the Earth rotation rate. The lower atmosphere in turn would spin the upper atmosphere up the Earth rotation rate.
