In the Navier Stokes equations I am confused as to why there is both a pressure term and a gravity term. Is this pressure resulting from differences in densities and temperature differences alone? I would think that the gravity term would be lumped into the pressure term. Can someone please clarify?

I am sorry if this makes no sense I am just trying to understand,

Thanks for your help.
