When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction. Instead, they crumple and fold until the rocks are forced up to form a mountain range. C. Majority of volcanoes are located within or near plate boundaries. What are examples of convergent boundaries? Which geologic features are associated with divergent boundaries? No definitive answer has proven exactly what is keeping the Rockies afloat yet, but it is believed to be a combination of very dense crust underneath the mountains (Pratt isostasy) and hot underlying mantle supporting the range's weight.
