Now it is your turn! When did any large amount of water on Mars
start
to become scarce and why? - AKA - where did most of it go?
Much of it evaporated off. To retain a given molecule in its
atmosphere
for long periods of time, a planet's escape velocity must be
several
times larger than the RMS speed of that molecule---a factor of 10
is a
good rule of thumb. Mars, as it happens, is on the wrong side of
this
critical value. The fact that the planet has basically no
magnetosphere
probably didn't help either.
So, you would say that when the Sun actually heated up and took off,
giving such as a strong solar wind, that the oceans of Mars and Venus
were
doomed?
Assuming I'm understanding this train wreck of a sentence properly, no.
Venus is massive enough to retain lighter molecules such as water. The
fact
that it still doesn't have oceans is due to other factors (i.e. being a
complete hellhole).
You think that's a train wreak of sentence structure? Wait till he
throws equal signs all over the place and pretends to write in
some sort of strange accent.
A strange accent you say? Why I'll keep my eyes peeled. I can't imagine wh
at THAT might look like.
Surely you've seen a Protobrain post full of 'der's and 've's Rev?
It's his cute little way of implying someone is a 'Group
Conservo'/Nazi.
