The process of star formation & how it leads to heat productions on the surface of the earth?

Can someone please explain the process of star formation and how it leads to heat productions on the surface of the earth?The process of star formation %26amp; how it leads to heat productions on the surface of the earth?Stars are formed when vast clouds of material in space start to collapse in on themselves, under their own gravity.

As they collapse, the matter in the centre gets denser and and denser, until it is so dense that the atoms there get "squashed" together. This is nuclear fusion, and is produces energy; this energy (heat and light) "push" outwards, counteracting the inward force from gravity.

Eventually, there is enough fusion happening at the centre that the outward force exactly balances the inward force, and the object stabilises as a sphere: this is a star.



At the same time as this is happening, the whole cloud is spinning (this is just an effect of what happens when interstellar clouds collapse). So it forms a loose disk; and in the outer regions of the disk, smaller portions of the cloud will also collapse under their own gravity, forming smaller bodies. Some of these will fall into the star, but others will be far enougn out that they will just orbit the new star: these are planets.



The heat from the star is radiated outwards, and it bathes the planets orbitting it; the closer a planet is, the more heat it gets. More volatile elements and compounds will tend to be "boiled off" the nearer planets (so they will have more of the heavier elements like silicon, metals, etc.), while the outer, cooler, planets will gather up these volatile substances, and will form gas-planets of ammonia, hydrogen, etc.
