Main Body
(I) Valleys: The rift valleys are result of vertical forces on the blocks along fault lines. The rifts have consequent deep valley in ocean topography too. Sea floor spreading contributes to mid-oceanic ridge and trenches, maintaining isostasy.
(II) Volcanic Landforms: The mantle plumes lead to formation of volcanic arcs and islands. The phenomenon of isostasy is crucial to study the topography, landforms of the earth showing a socio-economic impact on resident population.
