WebWhile the continental crust is 30–70 km thick, the oceanic crustal thickness is 6–12 km. The oceanic crust is also denser (2.8–3.0 g/cm 3) than the continental crust (2.6–2.7 g/cm 3 ). The average Archean crust is ~35 km thick, whereas the Proterozoic crust is significantly thicker (~45 km). WebA) Deposition in river deltas had changed the longshore current, resulting in erosion.
