PLATE TECTONICS
BY PAIGE WYLIE
PLATE TECTONICS
PIECES OF THE LITHOSPHERE ARE IN SLOW CONSTANT MOTION
CONVECTION CURRENTS
THE FLOW THAT TRANSFERS HEAT THROUGH A FLUID
SLAB PULL
THE PULL OF GRAVITY ON A PLATE THAT IS BEING SUBDUCTED
RIDGE PUSH
New less dense crust forming at divergent plate boundaries pushes older crust out of the way
DIVERGENT PLATE BOUNDARY
PLATES MOVE AWAY FROM EACH OTHER
RIFT VALLEY
LAND FORM THAT RESULTS FROM A DIVERGENT PLATE BOUNDARY
MID OCEAN RIDGE
UNDERWATER LANDFORM THAT IS CAUSED BY A DIVERGENT PLATE BOUNDARY
CONVERGENT PLATE BOUNDARY
TWO PLATES GOING TOWADS EACH OTHER
TRENCH WITH VOLCANIC ARC
LANDFORM FROM OCEAN VS OCEAN
TRENCH WITH ISLAND ARC
LANDFORM FROM OCEAN VS OCEAN
MOUNTAIN RANGE
CONTINENT VS CONTINENT (CONVERGENT)
Subduction
the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate. (Convergent)
DEEP OCEAN TRENCH
hemispheric-scale long but narrow topographic depressions of the sea floor
MARIANA TRENCH
is a deep ocean trench caused by convergent (ocean -ocean)
TRANSFORM PLATE BOUNDARY
WHEN TWO PLATES SLIDE NEXT TO EACH OTHER
Earthquakes happen
