With reference to Figure 2, describe the tectonic plate movements and explain why they move. [5]

Describe

-In Fig, 2, we can see the South America and Nazca plate moving towards each other at the convergent boundary.

-The Nazca and Pacific plate moving away from each other at the divergent boundary

-

Explain

-Plates move due to convection current in the mantle.

-Magma rise and expands from the core, cools and sinks near the surface. Cycle repeats

-Slab pull force causes plates to drive downwards into the mantle.
