Answer:

Wegener believed that there is three layers system within the earth, i.e. SIAL, SIMA and NIFE. SIAL is lighter than the SIMA. The continental masses are made of lighter materials (SIAL) and the oceans are made of denser material(SIMA). ... Thus, Wegener's theory of continental drifting begins from Carboniferous period.
