Destination 3: Andes Mountains Convergent Boundary

I've just arrived in Bogotá Columbia. The hotel I'm staying at is the La Manaña Hotel. Hopefully I'll be able to learn a little Español, although I'm not the best at languages. The hotel is known for it's great views of the Andes Mountains, and I believe I will have a great trip here.

There is an excellent example of a continental to oceanic subduction boundary here. You see, there are three types of subduction; ocean to ocean subduction, ocean to continent subduction, and continent to continent subduction. All of these are subsections of a convergent boundary. When you have a convergent boundary, it means that the less dense of the two substances will go on top of the more dense substance. So, a continent will always end up on top of the ocean. Now, back to the Andes. The Andes Mountains are, as I said before, an example of continental to oceanic subduction boundary. The Nazca Plate subducts below the South American Plate which creates the Peru-Chile Trench and the Andes Mountains. This kind of boundary makes deep-sea trenches, volcanoes along the coast (the Andes), and earthquake activity.
