Question

Which of the following is commonly expected near a "textbook" subduction zone (that is, near a subduction zone that is so perfect and free of confusing complications that you would use it in a textbook to teach students)?, A., Basaltic mid-ocean-ridge-type volcanoes.B., Andesitic stratovolcanoesC., Slide-past (or transform, with horizontal but not vertical movement) earthquakes and faults.D., Pull-apart earthquakes and faults.E., Basaltic hot-spot-type volcanoes

Answer 1

Answer:

B. Andelistic StratoVolcanoes

Explanation:

A stratovolacnoe is a tall, conical-like shape volcano composed of hardened lava, tephra and volcanic ash. Stratovolcanoes tends to form at subduction zones. Andesite are typically found in lava flows produced by stratovolacnoes. They are extensive igneous rock that are usually dark grey in color.

They are common rocks of the continental crust above subduction zones. Subduction zones are sites of gravitational sinking of earths lithosphere. Areas where it can be found includes all around the edge of Pacific, Russia, Indonesia, Japan etc.
