Plate Tectonics Flashcards
(24 cards)
Diverging plates
Constructive Plate Margin
Rubbing Plates
Conservative Plate Margin
Converging and/or Subducting Plate
Destructive Plate Margin
Focus
Origin point for an earthquake
Epicenter
Where the earthquake affects
Where do earthquakes happen?
Follow the plate margins in lines and clusters
Where do volcanoes happen?
Found at constructive and destructive plate margins, hotspots, linear and clustered
Only subducting desctructive
What causes an earthquake?
When there is a release of pressure/friction. Energy is released as seismic waves
How is the earth structured? (inner - outer)
Inner core, outer core, mantle, crust
What is ridge push and slab pull
A secondary movement from convection current which gravity affects
Younger crust
Oceanic crust
Thinner crust
Oceanic crust
Denser crust which makes it subduct
Oceanic crust
Made out of basalt
Oceanic crust
Constantly renewed and destroyed
Oceanic crust
Oldest crust
Continental crust
Thick crust
Continental crust
Light (doesn’t subduct)
Continental crust
Made out of granite
Continental crust
Cannot be renewed or destroyed
Continental crust
Mid-Atlantic Ridge
Constructive
San Andreas Fault
Conservative
Andes Young Fold Mountains
Destructive
What is a hotspot
Somewhere not on a plate boundary that gets volcanoes
