At the end of a long, stressful semester at school, you decide to head for the east coast for some rest and relaxation. After a terrible, violent, over-night thunderstorm, you awake to find that the closet door in your sea-side condo has become a time portal into the future. Half-awake in your pajamas, you reach in to get a shirt and get sucked into the portal. The next thing you know, you're standing on the side of a mountain about 6,000 feet [~1800 m] above sea level.  It is about 200 million years into the future and what used to be Cape Cod, Massachusetts, is now part of an extensive, high-elevation mountain range. There are towering peaks all around you as far as you can see. A bit confused and a bit light-headed from the sudden change in elevation, you sit down and take account of your new surroundings. In the mountain sides before you, you can see large sequences of bent and folded rock layers. In some of the mountain sides you can also see where the rocks have been broken and slid or thrust up on top of each other. What type of mountains are these? Volcanic, fold-thrust belt, or block-faulted? Citing evidence from the story, explain your answer. Explain the sequence of plate tectonic processes that will result in the formation of these future mountains. So, in this future time, does the Atlantic Ocean still exist? If no, then, what happened to it? What type(s) of metamorphism would have occurred here What type(s) of metamorphic rock(s) would you expect to find in this mountainous region?

Question

At the end of a long, stressful semester at school, you decide to head for the east coast for some rest and relaxation. After a terrible, violent, over-night thunderstorm, you awake to find that the closet door in your sea-side condo has become a time portal into the future. Half-awake in your pajamas, you reach in to get a shirt and get sucked into the portal. The next thing you know, you're standing on the side of a mountain about 6,000 feet [~1800 m] above sea level.  It is about 200 million years into the future and what used to be Cape Cod, Massachusetts, is now part of an extensive, high-elevation mountain range. There are towering peaks all around you as far as you can see. A bit confused and a bit light-headed from the sudden change in elevation, you sit down and take account of your new surroundings. In the mountain sides before you, you can see large sequences of bent and folded rock layers. In some of the mountain sides you can also see where the rocks have been broken and slid or thrust up on top of each other.
