Well, what do you mean if the Earth stopped rotating? If it just suddenly stopped.... well, actually, why would anything happen at all? If everything stopped moving, then why would anything be destroyed? Everything would have stopped, people, buildings, etc. But if the actual "sphere" stopped, and everything else was to continue moving, the atmosphere would suddenly be moving at around 1000 mph at the equator and 0 mph at the poles. Guess what that means: Extreme Coriolis Effect. Or to put it simply: Global Hurricane. In about 10 minutes or less, the winds would start to create spin, and all the while, would rip anything out of the ground that is not very well attached, and erode cities and mountains alike. Generally, this would be a bad thing.
