HEIGHT OF A CONTINENT ABOVE THE MANTLE. In the figure below, a simple model considers a continent as a block (density = 2,800 kg/m^3) floating in the mantle (density = 3,300 kg/m3). Assuming the continent is 35 km thick (the average thickness of the Earth's crust), estimate the height (in km) of the continent above the surrounding mantle. Continent (density = 2800 kg/m3) mg Mantle rock (density = 3300 kg/m³) 5.3. 7.4. 9.8 12.

Answer

So,    h= 35×28003300km          h= 29.69 kmSo, the height of the continent  that is above the rock is,             H-h= 35-29.69= 5.3 km
