Unit 3 Why Does The Sun Shine Ppt More mass can produce more pressure and drive ever higher temperatures at the core. most stars, like our sun, cease after producing carbon, oxygen, and neon. the core becomes a white dwarf and the. We give a quick 10 second answer and a longer, more in depth, answer if you want to how the sun continues shining every day forever.we take a look at what st.
Why Does The Sun Shine About The Sun Megakids Knowledge Video The size of the sun is a balance between the outward pressure made by the release of energy from nuclear fusion and the inward pull of gravity. the sun has enough hydrogen fuel to "burn" for a little over 5 billion years but will continue to burn for at least 5 billion more years after that fuel is depleted [source: national geographic]. In reaction 1, two hydrogen nuclei (1 h, protons) are fused to produce a heavy hydrogen nucleus (2 h, a deuteron). this is the usual way nuclear burning gets started in the sun. on rare occasions, the process is started by reaction 2. deuterons produced in reactions 1 and 2 fuse with protons to produce a light element of helium (3 he). Advertisement. generally speaking, the reason stars shine is that gravity has pulled a sufficient amount of hydrogen atoms into such close quarters that they start to fuse together into helium. Given our sun is a star and stars are suns, explaining the source of the sun’s energy would help us understand why stars shine. an early explanation offered as to why the sun shines came from.

Evolution of the sun the sun, although it has sustained all life on our planet, will not shine forever. the sun has already existed for about 4.5 billion years. the process of nuclear fusion, which creates the heat and light that make life on our planet possible, is also the process that slowly changes the sun’s composition. The core is the hottest part of the sun. nuclear reactions here – where hydrogen is fused to form helium – power the sun’s heat and light. temperatures top 27 million °f (15 million °c) and it’s about 86,000 miles (138,000 kilometers) thick. the density of the sun’s core is about 150 grams per cubic centimeter (g cm³).
