What energy powers stars throughout life?
Nuclear fusion. Mainly, converting hydrogen-1 to helium-4.
How are heavy elements formed during nuclear fusion?
This would be a fusion of three helium nuclei. This would happen towards the end of a star's life, it's not occurring in the sun at present, but obviously has happened in various stars in the past, which is why we have the heavy elements in our solar system
Why is nuclear fusion important to life on earth?
Life on Earth gets its energy from the Sun, which produces the energy through nuclear fusion.
Is the lifespan of small stars are much slower or faster than a massive star?
Yes we can say, life span of small stars are slower than bigger one because in the small star the nuclear fusion takes place at the moderate rate but massive stars require large amount of energy and therefore nuclear fusion consume all it's fuel in short Time As compare to small stars also mechanism of nuclear fusion in both case followed by different ways
Do main sequence stars have a shorter life cycle than other stars do?
All stars that are converting hydrogen into helium via nuclear fusion are said to be on "main-sequence". See related question for more information
What type of nuclear energy is more important for life on earth?
Nuclear fusion in the sun
How is the sun linked to nuclear energy?
The sun, like all stars, gets its energy from nuclear fusion. The Earth is only habitable for life because of the sun's radiant energy which reaches us. So we all depend on nuclear energy.
Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
Which kind of process supplies the energy for the stars?
The process that supplies the energy for the stars is nuclear fusion. Nuclear fusion is a process in which atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. In stars, the fusion of hydrogen atoms into helium is the primary source of energy. Under the intense heat and pressure of a star's core, hydrogen atoms are fused together to form helium, releasing a tremendous amount of energy in the form of light and heat. This process is what allows stars to shine and provides the energy necessary to sustain life on Earth.
How is energy linked to the sun?
The sun, like all stars, gets its energy from nuclear fusion. The Earth is only habitable for life because of the sun's radiant energy which reaches us. So we all depend on nuclear energy.
What is an example of nuclear fission which is applicable in your daily life?
We are constantly bombarded by cosmic radiation from space, and background radiation from the soil. However, both are background, and we have no biological processes that depend on nuclear reactions to survive.
How elements are formed in stars?
By nuclear fusion and neutron captureRight now the sun is fusing hydrogen into helium.Later in its life it will fuse helium into carbon.All elements are made inside stars. Massive stars are more efficient than low mass stars at making elements heavier than carbon.
