Question

Why is the Sun’s atmosphere hotter than its surface?

Answer 1

lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.

Answer 2

At the surface of the sun, the magnetic field lines look like many loops rising up out of the surface into the atmosphere and these loops are changing all the time. If the loops touch each other they can cause sudden explosions of enormous amounts of energy that heat up the atmosphere.
