The sun and the planets were organize from a b on the whole of gasses that contained 99% hydrogen and helium. at that place was only about 1% of some of the heavier elements, oxygen, silicon, iron, nickel, and others fearful gasses. The considerable ball of gasses was spinning, and the force of the spin caused gravity on the gasses. sedateness caused this huge ball of gasses to condense over millions of years. at foresighted last most of the gasses formed a central embody called the proto-sun. It notioned standardised a flat circle with a bulged in the midriff where the proto-sun was. Only about 10 % of the gasses were left as the breeze of the proto-sun. As time passed, gravity caused small balls of gasses to form, this is the governance of previous(predicate) planets. Chemical forces caused the helium and hydrogen to form into small grains (Heinz, 12). gravitational force caused these grains to pull to attempther 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. at last all of these elements formed into a sphere with a diameter of about 8000 m iles. The early earth was gasses, dust part! icles, and large chunks of material matter. As all of these were forced...
