How does an exfoliation dome form?
What will be an ideal response?
A large igneous mass formed deep beneath the surface, where confining pressure is great. As erosion removes the overlying bedrock (a process called unloading), the outer parts of the igneous mass expand. Joints form parallel to the surface. Continued weathering causes thin slabs to separate and fall off, creating exfoliation domes.
