Convergent (Destructive) plate margins

Question 1

What directions do plates move

Answer 1

Plates move towards each other due to slab pull

Question 2

Give an example of where convergent margins are found

Answer 2

Pacific plate subducted under Philippine plate to form Mariana trench

Question 3

What type of plates meet at a convergent margin

Answer 3

Oceanic and Continental
Oceanic and oceanic
Continental and Continental

Question 4

What is the process of constructive plate margins?

Answer 4

-the thinner, denser plate is subducted below the other (Area of subduction is known as the Benioff zone)
-the subducted plate will melt due to high temp creating an area of high-pressure
-magma is forced to rise through fissures to surface
-volcano forms

Question 5

describe how convergence can occur without forming a volcano

Answer 5

-when continental plus continental meet
-a plate cannot subduct because they are both too thick
-therefore sediment is folded upwards
-creating fold mountains (Himalayas)

Question 6

Features created at convergent plate margins

Answer 6

Volcanoes
trenches
Fold mountains

Question 7

What kind of volcanoes are formed usually

Answer 7

Cone or composite
Steep sided with violent interruptions

Question 8

What is the lava produced during a convergent volcanic eruption like?

Answer 8

High viscosity
High, volume
