I'd have thought a whole heap of shit would be different if the Earth were retrograde. The cause of being retrograde to begin with would mean the planet's surface likely would be vastly different.

I am not eve sure the plates would drift the same.

The operators of the VLT at Atacama would be unhappy.

There may not have even been tectonic plates at all.

OK.  How so?  That sound interesting.

That seems like a reach. The physics that cause the plates to move would remain, albeit with different vectors.

Kind of analogous to weather patterns being fundamentally the same in both hemispheres now, in spite of the fact that the Coriolis Effect manifests itself in the opposite direction.

Except that plates drifting in a new direction makes a completely different set of continents.  Therefore that map is only half right. Although, any such map would not be recognizable as having the same origin as earth (like that map leverages)  if the plates drifted all widdershins.

Okay, so there would have been plates, but not the same plates? That's fine, they're just crust floating on the mantle, right?

Yeah, but the continents are shaped by how they split.  Pull them apart in different places they will neccesarily be shaped differently.  Not to mention in different places.

Well as an example, Venus doesn't have tectonic plates.

It requires particular circumstances for them to occur, they are not a given. If the planet experienced an event that caused it to have retrograde spin, there's a chance the conditions for tectonic plates to form may not exist.

Keep in mind I said "may not exist" and not "would not exist". An event causing a planet to end up with retrograde spin is not a small thing, it is massive disturbance to the planet. Who can possibly know what geological status would exist after such an event?

You are over thinking it  ;)

It's a thought experiment. Given existing geography, how would a retrograde rotation affect earths climate and weather patterns?

So if the land masses might have formed differently if we had been rotating in the opposite direction, might this be a better representation...??  ;D
