A new study about
earth’s water says that the origin of water on planet earth may have not come
from far away comet or asteroid but on a meteorite within the inner solar
system that provide the water on earth and the earth is wet since it is formed
and not as known as dry. That meteorite is called “enstatite chondrites.” Meteorites are rocks.
The study suggests
or said that planet earth is born wet and thus when earth is formed or born it
is already have water or wet.
“A new study finds that Earth's water
may have come from materials that were present in the inner solar system at the
time the planet formed -- instead of far-reaching comets or asteroids
delivering such water. The findings published Aug. 28 in Science suggest
that Earth may have always been wet.” (Science Daily)
“Researchers from the Centre de Recherches Petrographiques et
Geochimiques (CRPG, CNRS/Universite de Lorraine) in Nancy, France, including
one who is now a postdoctoral fellow at Washington University in St. Louis,
determined that a type of meteorite called an enstatite chondrite contains
sufficient hydrogen to deliver at least three times the amount of water
contained in the Earth's oceans, and probably much more.” (Science Daily)
Enstatite chondrites meteorite according to
the report have the same or similar isotopic compositions on planet earth or
have the same stuff with planet earth that suggests that enstatite chondrites
could be the building blocks of planet when earth is formed or born.
“Enstatite chondrites are entirely composed of material from the inner
solar system -- essentially the same stuff that made up the Earth originally…… But
their isotopic similarity to Earth make them particularly compelling. Enstatite
chondrites have similar oxygen, titanium and calcium isotopes as Earth, and
this study showed that their hydrogen and nitrogen isotopes are similar to
Earth's, too. In the study of extraterrestrial materials, the abundances of an
element's isotopes are used as a distinctive signature to identify where that
element originated……."If enstatite chondrites were effectively the
building blocks of our planet -- as strongly suggested by their similar
isotopic compositions -- this result implies that these types of chondrites
supplied enough water to Earth to explain the origin of Earth's water, which is
amazing!"…. “ (Science Daily)
“The paper also proposes that a large amount of the atmospheric nitrogen
-- the most abundant component of the Earth's atmosphere -- could have come
from the enstatite chondrites.” (Science Daily)
According to the report there are already materials within the solar
system are hydrogen-bearing or have water contents since the planet formation
though temperatures are high.
“"Hydrogen-bearing material was present in the inner solar system
at the time of the rocky planet formation, even though the temperatures were
too high for water to condense."” (Science Daily)
The main point : Earth is formed or born wet or with water and that
water comes from within the solar system and do not come outside later when the
earth is formed or born. Earth is formed wet contrary to old belief that earth
is formed dry and later some comet or asteroid supply the water on earth.
