Volcano
Type of volcano that is dome shaped and formed by slow moving lava
lava dome
the hot layer that acts like plastic
Asthenosphere
Type of earthquake that is triggered by the activity of volcanoes
Volcanic Earthquake
What landforms did we talk about were formed by sheer?
transform faults
the upward motion that occurs when a heavy object is removed from the crust
Uplift
Type of volcano that is broad with gentle sloping sides.
Formed with faster moving lava
Shield Volcano
the process by which new oceanic crust forms and moves the old oceanic crust

Elastic Strain
Type of volcano is small with steep sides made of of pyroclastic material (ash and lava)
Cinder cone volcano
Acts like a conveyor belt as it moves the tectonic plates
Basal Drag
Type of earthquake causes little quakes that are caused by a underground caves or caverns give way
