Why is the atmosphere of the sun 1,000,000 degrees kelvin and the surface only 6,000 degrees?

Then the core jumps to 13,600,000 degrees. That's pretty hot.

So why is it cooler on the surface than in it's atmosphere?

That doesn't answer my question.

You would expect the core to have the highest temp, the surface to have the 2nd highest temp and the atmosphere to be the coldest.

Where do you get the idea that the atmosphere is 1MK and the surface only 6000 K?

Temperature is derived by how fast atoms/molecules are moving. The core being a plasma is going to be the hottest. The surface being nearly liquid is going to be at a more restful state as it transfers its heat energy to the immediate gaseous atmosphere.

I'm guessing though...

Rather, it forms a kind of nimbus around chromospheric features such as spicules and filaments, and is in constant, chaotic motion. The transition region is not easily visible from Earth's surface, but is readily observable from space by instruments sensitive to the far ultraviolet portion of the spectrum.

You could of wikipedia it.

Corona
The corona is the final layer of the sun and extends several million miles or kilometers outward from the photosphere. It can be seen best during a solar eclipse and in X-ray images of the sun. The temperature of the corona averages 2 million degrees Kelvin; although no one is sure why the corona is so hot, it is thought to be caused by the sun's magnetism. The corona has bright areas (hot) and dark areas called coronal holes. Coronal holes are relatively cool and are thought to be areas where particles of the solar wind escape.

Wiki

Although it is the nearest star to Earth and has been intensively studied by scientists, many questions about the Sun remain unanswered, such as why its outer atmosphere has a temperature of over a million K while its visible surface (the photosphere) has a temperature of less than 6,000 K

Could you Wikipedia the difference between "could of" and could have"?
