solar flare
Its called Altitude.
A temperature of 25 C is quite moderate, just a few degrees above normal room temperature.
The foundation
This is called a solar prominence when viewed on the suns limb or a solar filament when viewed with the solar disk behind it (when it will appear darker than the disk). Filaments/ prominences are formed in magnetic loops that hold relatively cool, dense gas suspended above the surface of the Sun.
Low Earth Orbit, such as the International Space Station. The Ionosphere is also in this range, though it extends both up and down. The same can be said for magnetosphere, all of which vary in altitude based on time of year and position over Earth, and the Exosphere (outer space), the base of which is can vary from 450km to 700km.

The lowest layer of the sun"s atmosphere and the layer from which light is given off is the photosphere.It is also called the surface of the sun.Its temperature is about 6,000k.Above the photosphere is the chromosphere.Its layer extends upward about 2,000 km above the photosphere. by:Marina Tamang of I.S125.
The chromosphere of the sun extends about 10,000 km above the sun's surface. This region is located above the photosphere and is characterized by a reddish glow during solar eclipses.
The layer above the photosphere is called the chromosphere. It is a region of the Sun's atmosphere where temperatures increase with altitude. Above the chromosphere lies the corona, which is the outermost layer of the Sun's atmosphere.
On a star, the chromosphere is the next layer above the photosphere.
the gases of the sun extend far beyond the photosphere, which may be considered the lowest level of the solar atmosphere. The region immediatly above the photosphere is called the chromosphere.
The area above the surface of the Sun, often referred to as the solar atmosphere, includes the photosphere, chromosphere, and corona. The photosphere, where visible light is emitted, has a radius of about 695,700 kilometers. The total surface area of the Sun can be calculated using the formula for the surface area of a sphere, which is approximately 6.09 x 10^12 square kilometers. Beyond the photosphere, the corona extends millions of kilometers into space, but its area varies with solar activity.
The layer above the photosphere is the chromosphere. It is thinner and less dense than the photosphere but is still visible during solar eclipses as a reddish ring around the moon.
Apex
chromosphere.....is the thin layer above the photosphere
The photosphere comes first, followed by the chromosphere and then the corona. The photosphere is the Sun's visible surface, the chromosphere is the middle layer above the photosphere, and the corona is the outermost layer extending into space.
