My "Heavy Air Atmosphere Theory" is proving itself each week. This week 3 states had high floods. Inch of rain each hour.WOW My boat is much needed. Pictures of the boat made full page,and now can be seen on Facebook. Will sell the plans for %$.00 and painting and Chief Grey Cloud WOW TreBert

The Moon has nothing to do with sustaining the Earth's magnetic field,
which originates in the liquid outer core of the planet.


are you serious? I mean for real do you even know what you are talking
about? I mean think about for a few minutes and stop thinking that you
are smarter than most people because obviously you are not. Why do you
think that there are still volcanos on earth? how is it that the core
has not cooled already?


It was once very hot indeed, and there's a lot of insulating material
around it, but it's true the interior of the Earth has not cooled as
fast as simple thermodynamics would suggest -- this was noted by Lord
Kelvin in the XIX century and was an important problem for early
geological theories positing an age in the billions of years.
Radioactivity is thought to be the principal source of excess heat,
since the end of the Late Heavy Bombardment anyway; although there's
little of the 'hottest' material left, the longer-lived isotopes of
uranium, thorium, and potassium are still reasonably abundant and
contribute a large proportion of the ~44 TW of heat the Earth radiates
into space, something like two-thirds of the total.

By what mechanism do you think the Moon influences the Earth's magnetic
field, or keeps the planet's interior hot? If you're thinking of tidal
friction, the tidal forces in the Earth-Moon system are not nearly
strong enough to account for the observed excess, producing only about a
tenth as much heat as the radioisotopes in the mantle do.

do you realize just how much uranium would be needed to generate that
kind of heat?

well lets see. first lets start with a few obvious clues. Venus doesnt
have a magnetic field also has no moon.
Mars has no magnetic field also no large moon. mercury does have a
magnetic field however the proximity of the sun may provide enough
gravity to allow mercury to have a monten core

and yes tidal friction caused by the large moon most certainly would
provide enough heat energy from friction to keep the core hot. you may
be thinking about the moon tidally moving the continents but that has
nothing to do with it. they dont go down near deep enough to keep the
core of the earth at the temprature that it is at.but the friction
from the liquid core as the moon pulls it from side to side would be
plenty.

and as the moon goes round and round and pulls the liquid iron or
whatever else it is around you get the eletric charge and volia you
get an instant magnetic field.

I think that maybe you watch too many movies or something

Actually, a life supporting atmosphere should be allowed to cover a fairly wide scope with genetic evolution and/or adaptation, not to mention what applied physics and its scientific levels of technology can help life of all sorts to survive in places thought too lethal for Goldilocks.

Without good intelligence and applied technology, much if not the vast majority of Earth is not Goldilocks suitable.

Earth's moon helps to airdate water,so fish can breath. Rain puts water on land surface so fresh watyer life can live . All life came out of the oceans one way or another. In about 25,000 years we will have found planets that do not have a land surface,and all life is found under their one vast ocean. Think of two of Jupiter's planets and you get the picture. TreBert

It would seem that you have failed to realize what goldilox means or
actually is. Goldilox is just a area in which the ability to sustain
at atmosphere such as the earth can survive with life. saying that
that a vast majority of earth is not that way means nothing. if only
one square mile was able to support life then that would mean earth
was in a goldiliox zone. if only one square inch was able to support
life then that would mean earth is in the goldilox zone.
