This model says that our solar system started off as a goon of gasses. The sun and the planets were form from a b on the whole of gasses that contained 99% hydrogen and helium. at that orchestrate was only about 1% of some of the heavier elements, oxygen, silicon, iron, nickel, and others fearful gasses. The huge ball of gasses was spinning, and the force of the spin caused gravity on the gasses. gravity caused this huge ball of gasses to condense over millions of years. at massive last most of the gasses formed a central bole called the proto-sun. It locutioned standardised a flat circle with a bulged in the midriff where the proto-sun was. Only about 10% of the gasses were left a s the breeze of the proto-sun. As time passed, gravity caused small balls of gasses to form, this is the composition of previous(predicate) planets. Chemical forces caused the helium and hydrogen to form into small grains (Heinz, 12). gloom caused these grains to pull to starther to form large ball and in conclusion large enough to be a planet. If you look at the age of the earth as one year, it formed in a week. The early earth consisted of billions and billions of tons of iron, nickel, oxygen and silicon.

There was a small amount of aluminum and magnesium. in the end all of these elements formed into a sphere with a diam of about 8000 miles. The early earth was gasses, dust pa rticles, and large chunks of unattackable m! atter. As all of these were forced...
