Hello! I don't know if I can just jump in (I'm new to the entire competition), but here are my answers:

Hawaii - Hotspot
         Iceland - Divergent & Hotspot
         Galapagos - Divergent & Hotspot
         Alaskan Aleutian - Convergent 
         Japan - Convergent
         Greenland - Divergent? it's not really [i]on[/i] the fault, but it's close
         Yellow stone - Hotspot
         Tahiti - Convergent
         Himalayas - Convergent
         Great Rift Valley - Divergent

I can verify that is correct (although Tahiti might be a hotspot, I'm not sure), so now you can ask a question.

Tahiti is a hotspot and so is Greenland but go ahead and ask a question

Place the following in approximate chronological order :
-Rodinia
-Ur
-Pangea
-Pannotia
-Hudsonland
Bonus : where does Rodinia get its name?

1. What kind of geologic structure is this?
2. Briefly describe how it is formed.

A ridged rock layer is pulled apart and the spaces in-between are filled by less competent rock.

Have anymore obscure structures? I'd like to fill that part of the binder.
