Answer:
According to this theory, the intense heat generated by radioactive substances in the mantle (100-2900 km below the earth surface) seeks a path to escape, • gives rise to the formation of convention currents in the mantle. • Wherever rising limbs of these currents meet, oceanic ridges are formed on the sea floor.
