Which two of the sun's layers are often reversed in larger stars?
core
radiative zone
convective zone
photosphere
chromosphere

Answer;

Radiative and concective zones

Explanation;The radiative zone of the sun is the layer of the solar interior that is between the innermost core and the outer convective zone.  In this zone the energy from nuclear fusion in the core moves outward as electromagnetic radiation.The convection zone is dominated by convection currents that carry energy outward to the surface. These convection currents carry photons outward to the surface faster than the radiative transfer in the core and radiative zone.

The answer is that they are composed mostly of liquid water.
