What two layers make up the lithospere?
The two layers of the lithosphere is made up of the oceanic lithosphere and continental lithosphere. The oceanic lithosphere is associated with oceanic crust and the ocean basins. The continental lithosphere is associated with the continental crust.
What are deep ocean trenches associated with?
Deep ocean trenches are associated with subduction zones where an ocean plate descends into the asthenosphere. The Ocean plate is heavier than a Continental plate which causes the Ocean plate to slide beneath the Continental plate. As the Ocean plate descends, a deep ocean trench is formed.
Which geographic feature is associated with subduction zones?
Subduction Zones are usually known to be part of the Destructive Plate Boundary. The changes that occur in this boundary are: Oceanic crust moves towards the continental crust, but due to the weight of the oceanic crust, the oceanic crust sinks and gets destroyed. This forms deep sea trenches and island archs with volcanoes. As the oceanic crust is forced downwards, the increase in pressure can trigger earthquakes to strike... Basically, the two plates (oceanic and continental) are associated with subduction zones.... Hope this helped ^ ^
What geologic features are associated with each type of convergent boundary?
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.
Would the most violent earth quacks be associated with spreading centers or subduction zones?
subduction zones

What subduction zone is ol doinyo lengai part of?
Ol Doinyo Lengai is not associated with a subduction zone. It is associated with the East African Rift, which is a continental rift.
What type of boundaries are subduction zones associated with?
Convergent oceanic - continental and oceanic - oceanic boundaries.
Is the geothermal gradient associated with divergent plate boundaries greater than the gradient associated with subduction zones?
Yes. Due to the thinness of the lithosphere at the divergent plate boundary, and the upwelling of hot mantle rock.
What are deep ocean trenches associated with?
Deep ocean trenches are associated with subduction zones where an ocean plate descends into the asthenosphere. The Ocean plate is heavier than a Continental plate which causes the Ocean plate to slide beneath the Continental plate. As the Ocean plate descends, a deep ocean trench is formed.

Is japan on a hot spot?
No. The volcanic activity in Japan is associated with a subduction zone.
Is a stratovolcano a divergent volcano?
No. Stromboli is associated with a subduction zone, which is a convergent boundary.
What are ocean trenches associated with?
Deep ocean trenches are associated with subduction zones where an ocean plate descends into the asthenosphere. The Ocean plate is heavier than a Continental plate which causes the Ocean plate to slide beneath the Continental plate. As the Ocean plate descends, a deep ocean trench is formed.
What is associated with the process of subduction?
Vulcanism and Orogeny
How do active margins differ from passive margins?
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
