ejs plate tectonics

QuestionAnswer
metal that is so hot it should be a liquid,but is under so much pressure that the particles squeeze to a solid inner core
hot liquid metal outer core
made of hot molten rock that is less dense than the core and is the thickest layer mantle
thin layer of cool rock; continental and oceanic crust crust
is the molten rock churning around in the mantle magma
when magma erupts to the earths surface lava
an area of volcanic activity that develops above rising plumes of magma hot spot
the huge underwater mountain ranges that are present in every ocean and circle earth mid-ocean ridge
the one plate sinking beneath another subduction
occurs where two plates move past each other in opposite directions transform boundary
the state that earth's lithosphere is broken onto huge,moving slabs of rock driven by motions theory of plate tectonics
the name that Alfred Wegener gave to the huge super continent that he proposed had once excited pangaea
the place where older crust is destroyed because two plates converge,or push together convergent boundary
fracture or break in the lithosphere where blocks of rocks move past each other fault
shaking of the ground caused by sudden movements along faults earthquake
vibrations in the earth caused by earth quakes seismic wave
point underground where rocks first move official start of earth quakes focus
point above or on ground directly above the focus epicenter
structures on a fault line can crack building collapse
smaller earth quakes that follows big ones after shock
power and gas lines snap from strain fires
falling rock and soil from slopes land slides
powerful waves that can move for thousands of miles with great height tsunamis
when ground shaking causes loose,wet soil to act like liquid,causing buildings to sink or tilt liquefaction
