Astudent made a model of isostasy by placing a block of wood in a beaker of water. how can the student demonstrate isostatic rebound using her model ? a. press the block down and let go b. pour out all the water c. blow vigorously on the block d. add water until the beaker over flows

Option (A)

Explanation: Isostacy is considered to be the state of gravitational balance between the lithospheric crust and the rocks of asthenosphere.

           When materials are added to the crust, the weight increases and  the block goes down. Whereas the materials when gets erode, weight of the block decreases and subsequently rises up.

  This state of balancing the crustal rocks flowing over the rocks of asthenosphere layer is known as the Isostacy.
