there are lot's of theories ofcours.
but the thing I wanted to explain
can be found on this link:
The Earth's Shifting Axis Another theory is that the whole earths plate. = every singele plate on the surface of the earth is moving at the
same time, because underneath it's a liquit. (like a bearing)
something else: i read somewere , the earth has a very big mark. it's the place weer 2 tectonic plates come to ghetter (or go away from each other)
most of these borderlines lies under water.
once in a while i don't know exicly, 100.000 years (?)
this "border" opens . all the water goes true this rift. and comes back out of it in the form of steam.
this way the chemical components changes in the seawater.
this would explain a radical change in samples scientist found in earlier seawater analasis.
but that would be quit a wonder if that would happen <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />)
finding Nemo will be another harsh task i think <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" />
