Convection currents form when the materials at the bottom of the
mantle are much hotter than the materials at the top of the mantle. The hotter materials float
up while the colder materials sink down forming a circular flow of magma.
Choices :
continental drift theory
convection current
seafloor spreading theory
internal structure of the Earth
plate tectonic theory

Answer:
Convection Current
Explanation:
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart.
