A simple model (Fig. 10–56) considers a continent as a
block (density = 2800 kg/m³) floating in the mantle rock
around it (density = 3300 kg/m³). Assuming the continent
is 35 km thick (the average thickness of the Earth's conti-
nental crust), estimate the height of the continent above
the surrounding mantle rock.
