Well, “What makes rain?” and “What makes it rain?” would yield two different answers. The former could be answered as simply as saying clouds. Or, the former could be answered with a more complex description of the composition of the rain. The answer for the latter would entail a discussion about the moisture content of air, temperatures, dew points, fronts, air masses, pressure gradients, etc.
