how is the andean type subduction zone different from the aleutian type subduction zone? are there pictures?

  • earth science -

    See the figure here:

    For the Aleutians, the subduction zone is in the ocean, and the volcanoes that form are the Aleutian islands themselves.

    For the Andes, the subduction zone is below the western South American coast itself, and the volcanoes that appear are just east of that, on land. The affect of the raising of the land (the very high mountain range) is much more apparent as well.
