Geologists matching rocks from opposite sides of the globe have found that part of Australia was once attached to North America 1.7 billion years ago.
Researchers from Curtin University in Australia examinedrocks from the Georgetown region of northern Queensland. The rocks — sandstone sedimentary rocks that formed in a shallow sea — had signatures that were unknownin Australia but strongly resembled rocks that can be seen in present-day Canada.
The researchers, who described their findings online Jan. 17 in the journal Geology, concluded that the Georgetown area broke away from North America 1.7 billion years ago. Then, 100 million years later, this landmass collided with what is now northern Australia, at the Mount Isa region.

Can we get it back?
Can I move there without a passport?....................
Do you remember when we were attached to Australia?
No, but the Amerikaryotes did..............
Well, yeah, it was a penal colony....................
World record visa overstay.
I always thought Australia fit where the Indian ocean is and attached to, the sub-continent.
Thanx for the post.
Obviously caused by man made global warming.
But what is the of that movement?
“Catalina Island,... is sinking into the ocean, and in a geologically short amount of time it will dip beneath the waves.”
Rest assured it will be blamed on sea levels “rising”, unless, by that time, they have found some new fad to blame it on.
Can’t say that I do but since my recent surgery I have a stomata
Do you have a video of the march for justice on C Span?
Poor Australia! Are they joining #MeToo?
“Do you have a video of the march for justice on C Span?”
I don’t think I do but I will check.
“I always thought Australia fit where the Indian ocean is and attached to, the sub-continent.”
I’m guessing it did at one time, there’s been two(?) or three(?) times where the earth has just had one large landmass. I recall as a kid hearing about the new theory of plate tectonics and how all the continents were once joined.
As a kid I loved looking at our globe, world book encylpedias, etc. I remember thinking that even an 8-year old kid can tell they all fit together at one point!
thanx
As a child I can remember thinking that Brazil looked like it fit into Africa. Before plate tectonics was mentioned. Evidence was gradually gathered and first widely publicized in a book the year before I was born. However, it wasn’t until the 1960’s that overwhelming additional evidence in a number of fields brought wide discussion and acceptance of the idea. By that time I had studied geology in college. where the evidence made sense to me.

It’s pretty amazing that it has only been 60 years or whatever that an “understanding” of how the earth works has come into being. I don’t recall what the earlier ideas were. On the other hand, even without a complete idea of how things work, we can know how SOME things work, and use that knowledge to find oil and minerals in the ground since way back when.
Makes me wonder what we will know in another 60 years.
“Well of COURSE travel through worm-holes is possible.”
Of course when our future generations can’t figure out that eating “Tide Pods” is a bad idea, I’m not sure.
Thanks glee'. Continental drift was dreamed up before WWII, and based on the superficial resemblance of the two coastlines. The plate tectonics model is warmed-over continental drift, and arose after the IGY which began in the mid-50s and continued for much more than one year. :^) The only evidence for the drift (still a much better name) consists of the magnetic lines preserved in rock near the major plate boundaries; it shows variations in the Earth's magnetic field orientation and/or intensity over time, and that has then been used to estimate the relative locations.
We could call ourselves “dreamers”?
