Plates Tectonics Boundary

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

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

• convection currents

• lava

• magma

• hot air

NGSS.MS-ESS2-1

proposed by Alfred Wegener, that the continents were once joined together and have since drifted apart

• theory of plate tectonics

• tectonic plates

• plate boundary

• theory of continental drift

NGSS.MS-ESS2-2

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

Examples of convergent boundaries where two continental plates collide producing a large mountain range.

• San Andreas Fault (USA)

• Japan (Asia); Aleutian Islands (Alaska, USA)

• Andes Mountains (S. America)

• Himalaya Mtns (Asia); Appalachian Mtns (USA)
