PMT - different plate boundaries destructive oceanic and oceanic Flashcards
1
Q
explain the process of a destructive oceanic and oceanic plate boundary?
A
- Heavier plate subducts leaving an
ocean trench - Fold mountains will also
occur - Built up pressure causes underwater
volcanoes bursting through oceanic
plate - Lava cools and creates new land called
island arcs
2
Q
what can form because of a destructive purely oceanic plate boundary?
A
fold mountains
underwater volcanoes
(when lava cools) island arcs
