Summary: down on greater slopes, the deposits could
eventually become even steeper because the
internal tidal energy decreases with increas-
ing seafloor gradient above the critical angle.
Other processes are at work in shaping con-
tinental slopes, and at least one of these,
turbidity currents, also has the potential to be
an important cause for the relative flatness of
continental slopes (20).
