Plate Tectonics Vocabulary

the plates SLIDE PAST EACH OTHER causing EARTHQUAKES

the idea that Earth's crust is divided into several plates that glide over the plastic-like mantle

two OCEANIC crusts move APART and CREATE MOUNTAINS under the sea; NEW CRUST is created when HOT MAGMA RISES from the mantle and SPREADS across the SEA FLOOR

the plates COLLIDE or COME TOGETHER

the plates DIVIDE or MOVE APART

two CONTINENTAL crusts DIVERGE and NEW FLOOR is created; over millions of years, it will eventually fill with water.

EXAMPLE of a TRANSFORMATION FAULT

formed at a SUBDUCTION zone

a STRING OF VOLCANOES AND EARTHQUAKES around the edges of the PACIFIC ocean

the OCEANIC crust goes BELOW the CONTINENTAL crust because it is more DENSE; VOLCANOES form on the continents; a TRENCH forms at the place where the plates COLLIDE

an EXAMPLE of a mid-ocean ridge; part of the LONGEST MOUNTAIN RANGES in the world
