What would happen if there were no rocks on Earth?

The “NO ROCKS ON EARTH” condition would be very difficult to envision. That would mean that there would be no crust, separating the mantle from the asthenosphere. The heat exchange from that condition would cool the mantle and a new crust would form. … which the heat from the exposed mantle would prevent from forming.
