Plate Tectonics and boundaries

Boundary between two colliding plates, often associated with mountain building, ocean trenches and volcanic islands

• plate boundary

• magma

• divergent boundary

• convergent boundary

the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates

• subduction zone

• lava zone

• nitrogen zone

• continental zone

THE PLATE BOUNDARY where two plates are moving apart, magma comes up to create new CRUST

• ridge

• divergent boundary

• convergent boundary

• plate boundary

The geographic feature where two plates are moving apart, magma comes up to create new crust

• lithosphere

• trench

• ridge

• magma

A long narrow deep depression in the ocean bed

• ridge

• fault

• trench

• rift

A deep crack in the Earth's surface associated with divergent boundary

• lava

• rift

• ridge

• trench

Circular currents in the mantle caused by the magma being heated by the core off the Earth.

• convection currents

• lava

• magma

• hot air

formed by two continental plates colliding and forcing each other upwards during convergent boundary

• grassland

• mountain ranges

• snow

• trench

Three Types of Plate Boundaries

• Transform (slide past)

• Convergent (collision)

• Divergent (pull apart)

• All the above

Transform Boundary

• Where two plates slide past each other.

• when two plates collide

• when two plates are pulling apart

• None of the above
