Question

Explain how subduction zones are formed.

Answer 1

#1. Two tectonic plates converge and then a subduction zone forms. One or both of the plates must be an oceanic lithosphere.

#2. Plate tectonics caused the continents to move away from Pangea.

#3. A. ocean currents

#4. C. the movement of Earth’s lithosphere

#5. C. underwater earthquakes

#6. Coastal cities are surrounded by water while cities in the middle of continents have land surrounding them. Land masses experience greater temperature changes than oceans do.

#7. D. all of the above.

#8. The mountains create a barrier to air moving so air rises and cools. Its moisture condenses, forming clouds and precipitation.

#9. Both have shifts of tectonic plates.

#10. A. Rifts

Answer 2

Where two tectonic plates converge, if one or both of the plates is oceanic lithosphere, a subduction zone will form. An oceanic plate will sink back into the mantle. ... But as it spreads away from the ridge and cools and contracts (becomse denser) it is able to sink into the hotter underlying mantle.
