Isostasy. The rock that makes up Earth’s crust is slightly less dense than the rock in the mantle, so it floats. Denser crust sinks lower into the mantle, while the lighter crust sits higher. This constant balancing between the downward force of the crust and the upward force of theRead More →

Identify the two forces that are kept in balance by isostatic adjustments. The two forces such as gravity by weight of the lithosphere and the buoyant force on the lithosphere by asthenosphere come under equilibrium to balance the geological processes. This state of equilibrium is known as isostasy. What isRead More →
