What is the temperature of the transition region?
Transition Region – The transition region is a very narrow (60 miles / 100 km) layer between the chromosphere and the corona where the temperature rises abruptly from about 8000 to about 500,000 K (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).
Where is the transition region located?
The transition zone is part of the Earth’s mantle, and is located between the lower mantle and the upper mantle, between a depth of 410 and 660 km (250 to 400 mi).
Where is the transition zone sun?
Above the chromosphere is a very thin layer of the Sun’s atmosphere about 100 km thick over which the temperature rises drastically from 20,000 degrees Kelvin in the upper chromosphere to over 2 million degrees Kelvin in the corona. This region is called the transition region.
What does the chromosphere of the Sun do?
The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.
How hot is the transition region of the Sun?
Heat flows down from the corona into the chromosphere and in the process produces this thin region where the temperature changes rapidly from 1,000,000°C (1,800,000°F) down to about 20,000°C (40,000°F).
How thick is the transition zone?
[15] The global transition zone thickness varies on the order of ±20 km, with maximum perturbations of about ±35 km.
What is the temperature of the corona of the Sun?
The sun’s corona can reach temperatures of around 1.8 million degrees F to 3.6 million degrees F (1 to 2 million degrees C), that’s up to 500 times hotter than the photosphere. But how is the sun’s upper atmosphere hotter than the surface?
How thick is the chromosphere?
about 2000 km thick
The chromosphere is about 2000 km thick. We only see this layer and the other outer layers during an eclipse. The corona extends outwards for more than a solar radius.
Is the chromosphere heated by the corona?
In the chromosphere, almost all the mechanical energy flux supplied to the outer solar atmosphere by magneto-convection is converted into heat and radiation, leaving a small amount to power the solar wind and the hot corona: the chromosphere requires over 30 times more energy than the corona and heliosphere combined.
What is the hottest region of the Sun?
The core
The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur.
Which region of the Sun has the highest temperature?
Core
Core. The hottest part of the Sun is the core, at 28,080,000°F, on average.
What is the solar transition region?
The solar transition region is a region of the Sun’s atmosphere, between the chromosphere and corona. It is visible from space using telescopes that can sense ultraviolet.
How is the transition region studied from space?
The transition region has been studied from space using instruments on several spacecraft including the Solar Maximum Mission and the Solar and Heliospheric Observatory. The Transition Region and Coronal Explorer (TRACE) mission is now actively acquiring data on the structure and dynamics of the transition region.
What is the transition region of the atmosphere?
The Transition Region. Heat flows down from the corona into the chromosphere and in the process produces this thin region where the temperature changes rapidly from 1,000,000°C (1,800,000°F) down to about 20,000°C (40,000°F). Hydrogen is ionized (stripped of its electron) at these temperatures and is therefore difficult to see.
What is the temperature of the solar corona?
The temperature jumps up rapidly to nearly one million kelvin, the temperature of the solar corona. This phenomenon is called the temperature catastrophe and is a phase transition analogous to boiling water to make steam; in fact, solar physicists refer to the process as evaporation by analogy to the more familiar process with water.
