Definitions For Plate Tectonics Flashcards
What is mantle drag
Convection currents in the mantle and asthenosphere carry the overlaying lithosphere along like a conveyor belt
1.) what is ridge push
The pushing force a plate experiences when it slides down the raised asthenosphere underneath mid ocean ridges
2.)what is slab pull
Denser oceanic plate subducts under the less dense continental plate into the mantle. Due to gravity
What is the asthenosphere
Layer of the earth that lies below the lithosphere
What is sea floor spreading
The formation of new oceanic crust due to the upwelling of magma at mid ocean ridge, and movements upwards
What is a subduction zone
When two plates move towards each other, the heavier one goes underneath
What is a destructive plate
Plates go towards each other
What is a constructive plate
Plates go towards each other
What is a conservative plate
Plates slide past each other
What is a convergent margin
Plates go towards each other
Destructive plates
What is a divergent plate margin
Plates go move away from each other
Constructive plates
What is a transform plate margin
Plates slide past each other Destructive
Conservative plates
