This process names a phenomenon in which the momentum of stellar material causes it to be carried through the tachocline, known as this process’s namesake “overshoot.” High-resolution images of the Sun’s surface appear granulated because of entities named for this process in the photosphere. This process occurs when the magnitude of the actual temperature gradient exceeds that of the adiabatic temperature gradient, according to the Schwarzschild criterion. For main sequence stars under around 0.35 solar masses, this process is the dominant form of energy transport. In a zone named for this process just below the Sun’s atmosphere, plasma circulates heat via this process’s namesake “currents.” For 10 points, name this thermal process exemplified by movement of warmer fluid upwards and cold fluid downwards. ■END■
