i think the answer is hydrogen and helium but I'm not positive so don't blame me if you get it wrong.
Gravity compresses gases at the center of a solar nebula until temperatures are high enough for nuclear fusion to occur
Gravity compresses gases at the center of a solar nebula until temperatures are high enough for nuclear fusion to occur.
A spinning disk is formed by the nebula shrinking is 4. The planets forming is 7. The planets form gas and dust accumulate as a nebula matter separates into galaxies. Nebula shrink to form a spinning disk,gravity pulls gases to the center of the disk .Gas at the center of the disk becomes hot and dense enough for nuclear fusion to begin
The solar nebula theory explains that planets are formed by solid bits of matter. What that matter is entirely dependent on the gas and substances available. The terrestrial planets in our solar system were located in the inner part of the solar nebula. This means that the temperatures were too high for the gas to condense into solids, leaving metals and silicates as the only solids from which the small and dense terrestrial planets could form. Meanwhile, the temperatures in the outer solar nebula were cold enough for the gases to form solid ice. The large Jovian planets then formed from the large amounts of ice particles available and were able to capture gas directly from the solar nebula because of how large they were.

The material at the center of a nebula clumps together as material is pulled there. This allows a star to form.
If enough matter comes together close enough, the collapse itself will generate enough heat (and pressure) for nuclear fusion. In other words, a star is created.
the protostar
A dead mammal
The Sun.
It formed the sun!!
A supernova occurs.
