isostasy
Isostasy.
Isostasy is the flotational balance achieved between rocks of the crust lithosphere and deeper mantle. This balance is maintained as lighter rocks of the crust "float" on the denser rocks of the mantle below.
Solid
Isostasy is the balance between the buoyant force of the lithosphere floating on the denser underlying mantle and the gravitational force pulling the lithosphere downwards.
Isostasy is the balance between the buoyant force of the mantle pushing up on the lithosphere and the gravitational force pulling the lithosphere downward. This balance helps maintain the equilibrium of the Earth's crust.
lithosphere
Isostasy. It refers to the equilibrium between the weight of Earth's lithosphere (which includes the continents) and the buoyant force exerted by the asthenosphere below, which causes the lithosphere to float.
The part of the mantle below the lithosphere is called the Asthenosphere.
The crust and uppermost hard rocky mantle, together, is known as the lithosphere, which is above the plastic-like upper mantle area known as the asthenosphere.
New lithosphere is constantly being produced at the oceanic ridges. Lithosphere is consumed at the subduction zones. A balance is maintained because older, denser proportions of oceanic lithosphere descend into the mantle at a rate equal to seafloor production.
