# What's wrong (if anything) with the tectonic plates on my fictional planet?

I'm trying to find someone (s) with enough geology knowledge to help me figure out some of the specifics of the world I'm building. (Earth-like in age, distance from star, size, tilt) I'm doing my best to reproduce what I can see on earth in roughly equal proportions. But I'm wondering if there's more accurate ways to do this. I'd love anyone who has the right knowledge to tear into this and tell me what could never happen, or what I haven't done enough, etc.) so I can make changes. Thanks! :)

Blue lines are divergent, Red are subduction, Yellow are transform. The arrows do not denote plate speed yet, they are just there to help me keep direction consistent on a sphere.

For the record, I've been following Artifexian's videos on this, but there's nothing about vetting the actual shapes in there.

• Hi Josh, welcome to Worldbuilding! I’m having a little trouble understanding your question - are you asking for general advice about the feasibility of your current tectonic plate breakdown, with special attention given to the rate of plate movement (as denoted by the length of the arrows drawn at each plate boundary)? Or are you looking for a mathematical model of how quickly each plate should move? If my experience on this planet has taught me anything, it’s that the Earth has a finite surface area and the rate plate production should indeed be equal to the rate of plate destruction.

• draw the Hadley convection cells that are driving this plate movement , preferably on a sphere, Jun 22, 2019 at 3:54
• @Jasen What do Hadley cell have to do with plate tectonics? Aren't they a purely atmospheric phenomena? Jun 22, 2019 at 16:44
• you get the same thing in the manlte (and in a pot of soup...) I used the wrong term above, they are convection cells, there may not be a special name in this context. Jun 22, 2019 at 19:26
