Photosphere, Corona, and Core
|
Detailed explanation-1: -The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
Detailed explanation-2: -The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona.
Detailed explanation-3: -In studying the structure of the Sun, solar physicists divide it into four domains: the interior, the surface atmospheres, the inner corona, and the outer corona.
Detailed explanation-4: -The chromosphere is a thin layer of plasma that lies between the Sun’s visible surface (the photosphere) and the corona (the Sun’s upper atmosphere). It extends for at least 2, 000 km (1, 200 mi.) above the surface.
