How many layers the sun have?
The structure of the sun is made up of four layers. At the very center is the dense, hot core. Around the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun's surface layer, known as the photosphere.
Is there gold in Sun?
Eventually, scientists calculated that the Sun contains almost 2.5 trillion tons of gold, enough to fill Earth's oceans and more. Still, that's just eight atoms of gold for every trillion atoms of hydrogen — a tiny amount when compared to the mass of the Sun.
What is the Sun made of?
The remaining amount of the Sun is made of iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, neon, calcium and chromium.
Why is the Sun made of layers?
The layers of the Sun are created because the temperatures and pressures increase as you move towards the center of the Sun. The hydrogen and helium behave differently under the changing conditions.
How many solar radius does the Sun have?
Astronomers believe that the core of the Sun extends from the center out to about 0.2 solar radius. And within this region, temperatures and pressures are so high that hydrogen atoms are torn apart to form separate protons, neutrons and electrons. With all of these free floating particles, the Sun is able to reform them into atoms of helium.
What are the elements that are formed when the hydrogen in the core runs out?
Once the hydrogen in the core runs out, they switch to fusing heavier and heavier elements, like helium, lithium, oxygen. Most of the heavier metals we see in the Sun were formed in other stars at the end of their lives. The heaviest elements, like gold and uranium, were formed when stars many times more massive that our Sun detonated in supernova explosions.
Which layer of the Sun is convective?
Convective Zone: Outside the radiative zone is another layer, called the convective zone, where heat from inside the Sun is carried up by columns of hot gas. Most stars have a convective zone. In the case of the Sun, it starts at around 70% of the Sun’s radius and goes to the outer surface (the photosphere).

What is the third and final region of the solar interior?
The third and final region of the solar interior is named the convective (or convection) zone.

The celestial body was formed from a collapse of a giant cloud that consisted mainly of hydrogen and helium. It is the brightest component of the solar system and the primary source of energy for life on earth (Aller, L.H).
What happens to the Earth if the core of the star doesn't absorb radiation?
Radiations from the core lose a lot of energy when passing through this zone to the earth. Life would be unbearable or there would be no life on the earth if this region doesn't absorb some of the radiations' energy.
