This confirms the idea that the mechanical waves generated from the convection zone are not very effective in heating the chromosphere and corona.
The convection zone reaches up to the sun's surface, and makes up 66 percent of the sun's volume but only a little more than 2 percent of its mass.
Starting at the outside and going down into the Sun, the zones are the corona, chromosphere, photosphere. convection zone. and finally the core.
