Convection currents in air and water occur because _
warm fluids are less dense than cold fluids
the molecules of warm fluids bump into the molecules of cold fluids

cold fluids are less dense than warm fluids
electromagnetic waves move the air or water

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
