Question

The region of refined, fiery air above the dense air of our atmosphere is called:

Answer 1

The region above the dense air of our atmosphere that could be described as 'refined, fiery' refers to the stratosphere, mesosphere, and thermosphere, including the ionosphere and exosphere. However, in the context of the Sun, it includes the chromosphere and corona, visible during solar eclipses.

Step-by-step explanation:

The region of refined, fiery air above the dense air of our atmosphere refers to the upper layers of Earth's atmosphere. Specifically, these regions include the stratosphere, where the air starts warming again due to the absorption of UV radiation by ozone, the mesosphere where meteors burn up, and the thermosphere where auroras and satellites are present. One notable boundary within these layers is the tropopause, which is the coldest part of the Earth's atmosphere and the transition between the troposphere and the stratosphere.

Above these layers, we encounter the ionosphere, a layer of ionized atoms and molecules important for radio communications, and the exosphere, constituting the upper limit of Earth's atmosphere, where atoms can escape into space. However, if the question is referring to the solar atmosphere, the fiery regions above the dense photosphere of the Sun would be the chromosphere and the corona. The chromosphere is only visible during a solar eclipse, while the corona, which was observed by ancients like Plutarch and Kepler during total eclipses, is the outermost hot atmosphere of the Sun.

Answer 2

What is the region of refined fiery air above the dense air of our atmosphere called?

Thermosphere. The Thermosphere extends from the mesopause to 430 miles (690 km) above the earth. This layer is known as the upper atmosphere. The gases of the thermosphere are increasingly thinner than in the mesosphere. As such, only the higher energy ultraviolet and x-ray radiation from the sun is absorbed.
