The other side of the world. Antipodes.

I come across this picture showing landmass on the globe and what landmass lays diametrically opposite it. I'm sort of surprised there is not more ''overlap'' of continents. It just worked out this way I suppose.
See the picture to see what I mean.

i am guessing there is probably an equation for this.
the balance between rock, lava, water, soil, condensation level, heat exchange level variant viscosity, thermo dynamics...
global climate change should also be a basic outcome factor as a function of the formula.
 
OP be damned. I had an Aunty Poad once, but she lived too far away for me ask why she had such a weird name...

I had no difficulty figuring out what it meant., and it's something one could measure in square meters if interested. Substantial, that, for an illusion.

"Substantial" in the sense of significance but not in the sense of substance.

My question is: What does the "overlap" have to do with anything? Why would we expect more?

Oh
OK
I read of a woman scientist that claimed that if there was an almost direct bolide impact that there would be a shock wave that would meet on the antipode creating things like the siberian or deccan traps.
Poor woman met with some derision as the proposed antipode impact was never found.(so far)

Pesky evidence getting in the way again. :)

There would be no impact on the antipodes, just the confluence of the shock waves.
 
Anyone ever find it suspicious that the highest (albeit volcanic) elevation in the Solar System is virtually antipodal to the deepest impact crater in the Solar System?

Am I just imagining that I posted an altitude map of Mars? With the Tharsis Bulge and the Hellas Basin clearly marked? :mad:

In my opinion, as posted, we wouldn't.

If you take the natural "opposite" as your predicted impact (since the waves were not just traveling great circle routes, but were affected by the planets rotation as well as the rock traversed)
the Deccan traps were quite near a possible node or "harmonic" focus of the shockwaves from the Yucatan impact of the K-T boundary. An extra shake, that is, on top of the straight wave propagation.
And they boosted eruption at about the same time.
Which as coincidences go, is striking.
