What happens in a subduction zone?

denser plate (oceanic) goes under the lighter plate (continental)

New cards
18

convergent plate boundary

two plates move towards each other -> <-

New cards
19

During subduction

magma rises

New cards
20

pressure from magma eventually causes

volcanic eruptions

New cards
21

transform boundary

plates move against each other ↑↓

New cards
22

Subduction creates

volcanoes, mountains

New cards
23

what happens along a transform boundary during an earthquake

sudden drastic movement causes friction and creates faults

New cards
24

what happens along a transform boundary between earthquakes

plates rubbing against each other creates pressure
