Hydrogen, helium, and nuclear fusion
Answer:
Coal is made by heating of woody plant material, and oil is made by heating of algae.
Explanation:
The coal and the oil are both fossil fuels. They have both been very important for the development that the humans have experienced since the Industrial Revolution as they were what provided the energy needed for this process, and they still do.
The coal is a fossil fuel that has formed from woody material, mostly from the Carboniferous forests. Once these forests collapsed, they were quickly covered with water, mud, and sediments. Over time they were covered with even more sediments, so they were getting deeper into the crust. As they were getting deeper into the crust this material was exposed to higher temperatures and pressures, leading to the formation of the coal over the course of millions of years.
The oil is a fossil fuel that has formed from the remains of the marine life, mostly algae. As the algae and the other marine organisms have been dying out, they have fallen on the bottom of the oceans, quickly being covered with the soft sediments. As more and more sediments have been placed on top of them, they too were getting deeper into the crust, so they were also exposed to higher temperatures and pressures, eventually leading to the formation of the oil over the course of millions of years.
Hertzsprung-Russell diagram to describes each star will be:
The star can no longer support nuclear fission because is has exhausted the supply of hydrogen - Sirius B
The stars hydrogen supply is running low so it is using hydrogen from outside the core. - Betelgeuse.
The stars experiencing nuclear fusion a score. - the sun.
<h3>What is Hertzsprung-Russell?</h3>
It should be noted that Hertzsprung-Russellb shows the relationship that exists between the temperature of a star and the luminosity.
In this case, the star that can no longer support nuclear fission because is has exhausted the supply of hydrogen is Sirius B.
The star where thd hydrogen supply is running low so it is using hydrogen from outside the core is the Betelgeuse and the stars experiencing nuclear fusion a score is the sun.
