10 Questions
What does the text describe as forming at subduction zones?
Mountain ranges
In an Ocean/Continent Subduction Zone, what lithosphere subducts beneath the more buoyant lithosphere?
Oceanic
What is indicated by the box in diagram (b) in relation to the crust transition?
An active continental margin
What do both scenarios (a) and (b) involve in terms of plate composition?
Oceanic crust caps both plates
What geological feature is specifically mentioned to form in an Ocean/Ocean Subduction Zone?
Accretionary wedge
What happens to the oceanic lithosphere at a subduction zone?
It is forced beneath the continental lithosphere
What occurs when the continental margins collide?
Formation of a mountain range
Which geological processes are associated with an active continental margin?
Earthquakes and volcanic activity
Why does subduction not occur when thick continental crusts collide?
Continental crust is too buoyant to be forced deep into the mantle
What is the main difference between the passive and active continental margins?
Involvement in geological activities
This quiz illustrates two types of subduction zones and the associated geological features that form as a result of the subduction process. The text explains the formation of topography and structures at subduction zones, mentioning the formation of accretionary wedge and island arc or volcanic arc. The diagrams represent two scenarios: Ocean/Ocean Subduction Zone.
