The convection zone is a layer in the sun's atmosphere that is responsible for the transfer of energy by convection. This layer is also known as the convective envelope or the radiation zone. The convective envelope is the outermost layer of the sun's atmosphere and is responsible for the transfer of energy by convection. The radiation zone is the region below the convection zone where energy is transferred by radiation. Other synonyms for the convection zone include the outer atmosphere, the solar envelope, and the convective zone. Regardless of the term used, the convection zone plays a vital role in the sun's energy production and ultimately drives all of the solar system's dynamics.
