Tectonic Plates Crossword

The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle.
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.
a vent in the earth's crust through which lava, steam, ashes, etc., are expelled, either continuously or at irregular intervals.
a long high sea wave caused by an earthquake, submarine landslide, or other disturbance.
a cavity in the ground, especially in limestone bedrock, caused by water erosion and providing a route for surface water to disappear underground.
the gradual movement of the continents across the earth's surface through geological time.
is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates.
