I was reading some information about the Sun and I came across something that confused me. (I am only listing the portion I found confusing.) The diagram/explanation of each layer of the sun gave these stats. Radiative, 5,000,000 K; Convection, 5,800 K; Photosphere, 4,400 K - 6,600 K; Chromosphere, 30,000 K.

How does the temperature go from hot to cooler and back to hotter again? Why are the outter temperatures so much hotter than the "middle" regions?

It's still a bit of a mystery, but there are a few theories floating around.

Here (http://www.astronomycafe.net/qadir/q39.html) is a short answer.

This (http://www.sunblock99.org.uk/sb99/people/KGalsgaa/sb99_num.html) has a little more.

It's been a while since I've seen anything new on this phenomenon, but it is quite interesting.

Wait until you try to find the magnetic poles. #-o If you think that one is hard check out the actual rotation. :o

Here's an interesting graphic (http://www.enchantedlearning.com/subjects/astronomy/planets/earth/Atmosphere.shtml) about the Earth's own atmospheric regions, and how temperature varies within them.
