No, it is hydrogen that is the fuel for fusion in the sun
Helium is produced by fusion in the interior of the Sun.
The high temperature and pressure in the Sun's interior causes nuclear fusion.
High temp and pressure
In the Sun's interior, nuclear reactions primarily involve the fusion of hydrogen nuclei (protons) to form helium nuclei. This process, known as nuclear fusion, releases energy in the form of light and heat. This energy is what powers the Sun and sustains life on Earth.
Interior of the sun.
No. The sun is about 1% oxygen but it does not carry out combustion. It is instead powered by nuclear fusion.
No, the sun does not burn in the way that we typically think of burning. It undergoes nuclear fusion, where hydrogen atoms combine to form helium, releasing energy in the process. Oxygen is not required for this reaction to occur.
Mainly hydrogen and some helium. The helium is created when the hydrogen undergoes nuclear fusion.
In the core of the Sun, hydrogen atoms fuse to form helium in a process known as hydrogen fusion. This is the primary fusion process occurring in the Sun. As the core hydrogen is depleted, helium fusion into heavier elements like carbon and oxygen will occur in later stages of the Sun's evolution.
The Sun's atmosphere is much cooler compared to its extremely hot interior where nuclear fusion occurs. The atmosphere consists of the chromosphere, transition region, and corona, with unique temperature and density profiles. The interior comprises layers like the core, radiative zone, and convective zone, where energy is produced through nuclear fusion.
The Sun's interior is composed of the core, radiative zone, and convective zone. The core is where nuclear fusion occurs, generating the Sun's energy. The surface of the Sun is known as the photosphere, which emits light and heat into space.
With the exception of vanishingly small amounts from other stars, heat does not reach the sun. The sun is a source of heat due to the nuclear fusion underway in its interior.
