Question

How are currents that form in heated air similar to currents that form in heated water????????????

Answer 1

Sounds like more context is needed to get a better understanding of the problem, but I'll give a crack at it.  I'd say that they're similar because, in both cases, heated currents is a result of the density difference in warmer versus colder fluid.  Hot things expand, and hence are less dense (less mass per volume).  So if you heat part of a fluid (both air and water are technically considered fluids), the hot part rises because it's less dense then the cold part that isn't heated.
