  • Get into pairs
  • Label yourself 1 and 2
labels
Labels:

Neatly add these correct labels:

Generally explosive volcanic eruptions.

Magma rising to form volcanoes.

Plate being forced into the mantle

Deep, violent Earthquakes

One plate is denser than the other so sinks.

Plate melting.

Subduction zone

Oceanic plate

Continental plate

Ocean trench

Make sure you can explain how earthquakes and volcanoes occur at this plate boundary

the andes
The Andes

The Andes are found at a destructive margin along the western coast of South America. The liquid magma rises towards the surface to form volcanoes such as Aconcagua. The collision of the plates also causes uplift and the growth of the Andes.

the collision zone
The Collision Zone
  • When continental plates collide head on with other continental plates, the result is upheaval!
  • Similar densities – neither plate is subducted
  • Gradual forward movement of each plate creates extreme pressures= earthquakes
  • Over time, the rock strata become folded, and rise to create mountain ranges
