Nebular Cloud Theory
The proposition of this theory is that the earth originated
from a nebular ,a mass of dust clouds and gases
circulating in the atmosphere.
As the nebular rotated ,it flattened into a disk .
This disk underwent a succession of pressure which
moulded it into planet Earth.
Starting off in essential gaseous state ,it passed through
molten space during which heaviest materials settled at the
nucleus as the lightest got flung to the peripheral zone.
The earth retained some of the materials in this molten
state specifically in outer core and Mantle.
The lightest materials from external remained exposed and
experienced prolong cooling thereby forming the earth's
crust .
The rest of the substances contained in the nebular
retained their gaseous state comprising the earth's
atmosphere.
