How does the sun generate energy today?Group of answer choicesChemical reactionsNuclear fusionNuclear fissionGravitsational contraction
Solution
The sun generates energy today through Nuclear fusion.
Here's a step-by-step explanation:
-
The sun's core is extremely hot and dense. The pressure and temperature are so high that hydrogen atoms come together and fuse to form helium - this process is known as nuclear fusion.
-
In this fusion process, a small amount of the hydrogen's mass is converted into energy according to Einstein's equation, E=mc^2. This means that energy (E) is equal to mass (m) times the speed of light (c) squared.
-
This energy then radiates outward from the sun's core and eventually reaches the surface, from where it is emitted as light and heat.
-
This energy is what we receive as sunlight on Earth.
So, the correct answer to your question is Nuclear fusion.
