The crust is divided into a number of large pieces called:
plates, which move over the convection currents of the magma.
tectonic plates, which float on the magma of the crust.
plates, which float on the tectonic convection currents of the mantle.
tectonic plates, which float on the magma of the mantle.
The Mid-Atlantic Ridge is evidence of:
plate tectonics.
sea-floor spreading.
continental drift.
convection currents in the mantle.
Plate movement is most likely caused by:
the plates floating on water.
sea-floor spreading.
the plates floating on the semiliquid mantle.
continental drift.
