ES 771 Space Imagery


VOLCANOES are common along tectonic plate boundaries where plates are either diverging--oceanic ridges and continental rift zones, or converging--oceanic trenches (subduction zones) and continental collisions. Volcanoes also appear over isolated hot spots within plates, such as Iceland, Yellowstone or Hawaii. Types of volcanic eruptions and deposits vary enormously with different lava compositions and geographic settings.
