I'm currently working on a world map. This will be used for various things. I'm trying to get it realistic looking and I want it to make sense scientifically. It doesn't have to be 100% perfect, just close enough that it won't matter.
Red: Mountain Ranges
Green: Volcano Activity
Dark Blue: Undersea Trenches
Light Blue: Undersea Mountains
On the first map of the landmasses: The landmass to the bottom right I'm imagining having went north around the planet and came back up from the south.
If more information is needed I will be glad to edit the post and add in the relevant info.
