The asthenosphere lies below the lithosphere and the oceanic crust. If oceanic-continental convergence was to cease (unlikely as to the enormous momentum involved) subduction would presumable lessen and, as the momentum of one plate against another stopped moving, an equilibrium state would presumably exist.
Aesthenosphere
The aesthenosphere, which is located in the top part of the Earth's mantle is the layer lying underneath the tectonic plates. Collective movement in these plates cause a gradual rise in the aesthenosphere, thereby resulting to land elevation.
Earthquakes.... Volcanoes..... Tsunamis..... Landslides.... Avalanches can happen
The tectonic plates were moving.
The plates will then stop moving
Tectonic Plates are moving in all directions...
they just happen earthquakes are caused from the plates under earths surface moving
Divergent plates are found in places where the tectonic plates are moving away from each other.
the earth will stop moving around its orbit
The continental plates were moving at that time and separated apart
They'd stop moving.
Mountains move by the plates under the earth moving. When plates move, often tsunamis and earthquakes happen. Mountains move 1 cm per year when the plates move!
