Plate margins - Coggle Diagram
Plate margins
Constructive (Divergent) : :
Plates move apart
Magma rises → new crust formed
Volcanoes (shield) + earthquakes
Examples: Mid-Atlantic Ridge, Iceland
Destructive (Convergent)
Plates collide
Oceanic subducts under continental
Deep sea trenches, fold mountains, volcanoes, earthquakes
Example: Andes, Mariana Trench
Conservative (Transform)
Plates slide past each other
No crust created/destroyed
Earthquakes
Example: San Andreas Fault
Collision Boundary
Two continental plates collide
No subduction (both buoyant)
Fold mountains form
Example: Himalayas
Hotspots (Away from margins)
Rising magma plumes
Volcano chains as plate moves
Example: Hawaii islands
