What is Lithosphere
Is the layer of gasses surrounding the earth
What is Atmosphere
The largest tectonic plate
Pacific plate
Boundary where plates slide past each other
What is Transform plate boundary
Is when convection currents in the mantle produce a force (like a conveyer belt)
What is Basal Drag
The process where new ocean crust forms along a mid-ocean ridge and old crust moves away.
What is Seafloor spreading
The least dense layer of the earth
What is Crust
The smallest plate

What is Geosphere
Technology used to study the moment of plates
Global Positioning Systems
Brings metamorphic and igneous rocks from deep in the crust to the surface
What is Uplift
Formed when plates collide and the denser plate sinks below the more buoyant plate.
What is Subduction
Plates collide and there is no subduction they lift and form _____
What is Mountains
Sphere which allows movement in the lithosphere
What is Asthenosphere
Where we see large amounts of volcanic activity
What is the Pacific plate (Ring of Fire)
Occurs when stress and strain cause rocks to buckle and fracture
What is Folds
When the slab sinks, pulling the rest of the plate with a force.
What is Slab pull
Is molten rock below the earths surface.
