Question

JIf additional weight is added to a piece of crust, how will the crust respond?


by creating new rock


by moving horizontally


by rising


by sinking

Answer 1

If additional weight is added to a piece of crust, the crust will generally respond by **sinking**. This is due to the principle of isostasy, where the Earth's lithosphere adjusts to changes in load. When weight is added, the crust compresses and sinks deeper into the underlying mantle until a new equilibrium is reached.
