The youngest rocks are exposed in the center.
The oldest rocks are exposed along the edges of the dome.
The rocks in the center are the same age as those along the edges.
13.The collision and joining of crustal fragments to a continent is called continental ____.(1 point)subduction

20.Briefly explain the difference between elastic deformation, ductile deformation, and brittle deformation.(3 points)
21.Briefly describe the relative movements and dominant stresses involved in the four major types of faults.(4 points)
Oh boy! A real test! Its been a while…Rocks, Elastic, Normal, Mountains, Age, FTC,*7-9 sorry no go without the pics, Black Hills I think, Basin, Oldest in center, Accretion, Himalayas, Wedge?, Japan, Rise, Orogenesis, Young.
Elastic is the ability for a material to bend under stress and not break (like an eraser). Ductile is the materials ability to be stretched and not break (like how copper wire is formed by pulling it through a small hole). Brittle is the point in which the stress on the material is too much to handle and breaks (like snapping your pencil, it'll break long before the eraser).
Normal-extentional Reverse-compressional Thrust-compressional Strike-Slip/Transform-Shear
I'm fairly certain on most of these, review your notes either way.
