As time passed, gloom caused small balls of gasses to form, this is the formation of previous(predicate) planets. chemical substance forces caused the helium and hydrogen to form into small grains (Heinz, 12).

The early earth consisted of billions and billions of tons of iron, nickel, oxygen and silicon.

there was a small cadence of aluminum and magnesium. Eventually all of these elements formed into a field of honor with a diameter of about 8000 miles. The early earth was gasses, ashes particles, and large chunks of solid matter. As all of these were forced...
