Planet Earth
The "Earth" is the fifth largest planet in this system and the third planet from
the Star called the "Sun". The "Earth" has a mass of six sextillion, 588
quintillion short tons. Using the parameters of an ellipsoid, the length of the
equator is 24,901.55 miles. The length of the meridian, running north and south,
is 24,859.82 miles and the equatorial diameter is 7,926.41 miles. Therefore the
area of this referenced ellipsoid is approximately 196,938,800 square miles. The
Earth's "Atmosphere" is a blanket of gas composed of "Nitrogen", "Oxygen" and
"Argon" in amounts equal to about 78%, 21% and 1% by volume. Also present in
very minute quantities are the gases of "Carbon Dioxide", "Hydrogen", "Neon",
"Helium", "Krypton" and "Xenon". This "Atmosphere" or blanket of gases rests on
the Earth's surface with the weight equivalent to a layer of water 34 feet deep.
For about the first 300,000 feet or 56.8 miles upward the gases remain in the
proportions stated above. The outstanding feature of the Earth as a planet is
the presence of liquid water. Water is vital not only for the biosphere but also
for the geologic processes of erosion, transport, and deposition that shape the
Earth's surface. Yet, if the Earth were closer to the Sun, the water would be
vaporized; if farther, it would turn to ice. Two-thirds of the terrestrial
surface is covered by oceans. It was long thought that the continents,
constituting the remaining one-third of the surface, had been fixed in position
throughout the Earth's history. Gradually some Earth scientists dared to suggest
that there had been major continental displacements, and finally, during the
1960s, investigators developed the full picture of seafloor spreading and plate
tectonics. The continents, though constantly in motion, are in fact the oldest
portions of the Earth's surface, for the seafloor is created at ridges and
consumed at trenches on a geologically short time scale. Other planets, notably
Mars and Venus, have surface features that suggest some elements of plate
tectonics, but none is known to be undergoing the constant rejuvenation of the
surface as is the Earth.
The Oceans of the Earth are in a state of rejuvenation
by being re-circulated within the molten magma of the Earth at the deepest parts
of the Ocean floor. Water is taken in at tremendous pressures (3,500 p.s.i.)
through openings in the Earth's crust. It is then re-boiled and discharged
through naturally formed tubes known as "Black Smokers". The rejuvenated water is discharged at a higher
pressure and temperature than the Ocean floor. The deepest research dive has
been to 35,810 feet {6.7 miles} in the Marianas Trench in the Pacific Ocean
where the pressures reached over 15,500 p.s.i.. Some "Black Smokers" or vents
have been found and harvested at over 7,900 ft. at pressures exceeding 3,400
p.s.i.. For more on "Black Smokers" Clik on this Link -> "Black
