When you take into account landslides, subsidence, heavy rainstorms, animal activity, plant growth and decay, it would not be uncommon in many arid areas.

And that conjecture is based upon?

I spent a little over a year working in a desert, helping with an irrigated citrus orchard and observing the plants and terrain. I went on frequent forays and noticed a lot of changes in the soil due to all the above-mentioned factors. I see that I forgot to add wind erosion to the list.

What is your scepticism based on?

Effective temperature: 5772 K
Temperature at top of photosphere: 4400 K
Temperature at bottom of photosphere: 6600 K
So, from immediately outside, the Sun appears to have a temperature of about 5772 K, a result of the combination of the temperatures throughout the, by definition, semi-transparent photosphere.

That does not seem to add anything to the discussion, unless you want to elaborate?

And the 5500 value for the sun's surface is just this value in Centigrade but the units are sometimes misquoted as Kelvin!

Maybe we should end this discussion now. Unless we have any major new points?
