When there was only one land mass, is there any scientific theories if that would change the rotation of the earth on its axis or around the sun?
It would not. The mass of the Earth doesn’t change, and angular momentum is conserved.
I was curious since mass would seem lopsided. I guess not enough. Thanks for answering.
The crust of the earth is relatively thinner than the skin of an apple from my understanding. So I wouldn’t expect anything happening on the crust to have a huge impact on that kind of behavior. Granted, even small changes could be noticable.
That’s a great point. When it comes to the Earth’s mass, the surface is barely a factor.
My layman’s understanding is that the water mostly makes up for it, and that more wobble comes from the moon than any inconsistency in land-mass distribution
No, but the climate was probably cooler and drier than today. In fact the interior regions of the supercontinent might have been too dry to support most life-forms.

You don’t remember the theory of Pangea and plate techtonics from school?

Darth Plagueis perhaps?

Ahhhhh gotcha, no worries :)
this bitch don’t know bout Pangaea
You’re right, you shouldn’t.
But if you don’t read the explanation you don’t get to see the funny “citations needed” like
Of course, coastlines are inanimate objects, and have no concept of plagiarism, let alone know how to perform it.[citation needed]

I didn’t get it either at first. If he had cut the word off at a different point?
I don’t know how you could make it clearer than just leaving off the last letter.
They literally want it spelled out for them
Because it wasn’t funny. I like XKCD but they can’t all be winners.
