**THE STRUCTURE OF THE SUN AND SOLAR PHENOMENA (BY ZUSYAHAIRAH BINTI MOHD NA'AIM)
THE STRUCTURE OF THE SUN
The Sun is the only star in our solar system that gives all of the planets in the system light energy.
Different spherical layers that are hard to define with a physical limit depict the structure of the Sun
The many layers or components of the Sun are identified by the physical roles they fulfil.
The layers of the Sun are divided into two larger groups the outer and the inner layers
The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the
THE OUTER LAYERS
CORONA
The Corona is the visible circle surrounding the moon that covers the Sun during a solar eclipse.
The corona's temperature typically varies between one million and two million kelvins.
its width is a few million kilometers.
TRANSITION REGION
a very thin layer between the chromosphere and the corona
The temperature jumps sharply from 8,000 to 500,000 K.
CHROMOSPHERE
Has a width of 2,000 to 3,000 km.
The chromosphere's density drops and its temperature rises from 4,500 to 100,000 degrees Celsius as it goes out from the nucleus.
PHOTOSPHERE
Nearly all of the visible light that the star transmits into space is produced by it.
sunspots are formed
The photosphere has a breadth of around 400 kilometres with a temperature that decreases with distance from the nucleus, ranging from 7,500 to 4,700 Kelvin.
THE INNER LAYERS
CONVECTION ZONE
located above the radiant area
Photons are readily absorbed, and solar gases are no longer ionised.
RADIATIVE ZONE
receives the energy generated inside by radiation
composed of plasma, that is, large amounts of ionized hydrogen and helium.
CORE
nuclear fusion reactions are generated
It is made out of gas that, because of its magnetic field and high temperature and pressure, appears as plasma.
SOLAR PHENOMENA
Solar phenomena are natural phenomena which occur within the atmosphere of the Sun
Solar phenomena refer to the various natural events and activities that occur on the Sun’s surface
There are many various types of solar phenomena, and each one occurs due to unique solar conditions.
1. SOLAR FLARE
intense radiation flares that result from the magnetic energy released by sunspots on the sun's surface.
caused by highly charged particles interacting with the magnetic field of the sun
may release radiation in all electromagnetic spectrums, including radio waves, x-rays, and gamma rays. They are strong enough to impact Earth's ionosphere, which might interfere with satellite operations, communications, and even your solar panels.
2. SOLAR ECLIPSE
happens when the moon moves in front of the Earth and the sun, momentarily blocking its light.
There are three types: total, partial, and annular
During a total eclipse, the sun's corona is visible since the moon fully obscures it. Only a bit of the sun is hidden when there is a partial eclipse.
When the moon passes over the centre of the sun, it creates an annular eclipse, which appears as a ring.
3. SOLAR AURORA
a brilliant show of natural light in the sky that is mostly visible in high-latitude areas in the Arctic and Antarctic
brought about by the interaction of the Earth's magnetic field and atmosphere with the solar wind, a stream of charged particles that emanates from the sun.
The resulting shimmering curtains of color are typically green, but can also be pink, red, yellow, blue, and violet.
