• deep sea trench
• continental shelf
• dormant
• fault

A tectonic plate boundary where two plates collide, come together, or crash into each other.

• transform boundary
• convergent boundary
• fault
• magma

A long, narrow deep depression in the ocean floor which typically runs parallel to a plate boundary and makes a subduction zone.

• continental shelf
• dormant
• deep sea trench
• magnitude

Boundary between tectonic plates in which the two plates move away from each other, and new crust is created between them

• divergent boundary
• midocean ridge
• convergent boundary
• tsunami

inactive

• hotspot
• volcanic rock
• shearing

A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.

• plate tectonics
• dormant
• extinct
• uplift

A break or crack in the earth's crust

• fault
• extinct
• dormant
• magma

A narrow band of vertical fractures in the ocean floor; fracture zones lie roughly at right angles to a mid-ocean ridge, and the actively slipping part of a fracture zone is a transform fault.

• continental shelf
• fracture zone
• dormant
