What aspect of plate tectonics is least understood and requires further research? question 3 options: a. the driving mechanism (what causes plates to start moving one direction and then stop or change directions) b. why melting occurs and what types of magmas are generated c. what types of earthquakes to expect in association with the different plate boundaries d. what types of mineral deposits are associated with particular tectonic conditions?

c.what types of earthquakes to expect in association with the different plate boundaries

Explanation:

The plate tectonics can be understood by the association of the movement of the plates as there are three type of the plates such as the divergent and the convergent and the transform boundaries and they create a different set of landscapes and their many types of the 7 major and the 20 minor plates on earth.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
