5. What happens in the theory of isostasy?

Respuesta :

Answer:

plate tectonics

viscoelastic

isostatic equilibrium

asthenosphere

This theory explains how the tectonic plates in the lithosphere able to move freely on the asthenosphere. The lithosphere is less dense than the asthenosphere. There is an equilibrium of the buoyancy between the lithosphere and asthenosphere

Explanation:

Just finished on Penn foster this is correct :)

The theory of isostasy assumes that the lithosphere is less dense than the asthenosphere. Hence, the lithosphere flote over the mantle.

1. Theory of Isostasy was formulated by the English mathematician’s John Pratt and George Airy

2. Due to the thick and viscous material in the asthenosphere, the liquid is called viscoelastic.

3. Isostatic equilibrium is reached when areas of the lithosphere stop rising.

4. A change in density occurs as a result of asthenosphere compression

Theory of Isostasy:

It states that the lighter lithosphere must flote over the thick-viscous mantle. This theory was given by the two English mathematician's John Pratt and George Airy.

  • The asthenosphere is a thick-viscous and the uppermost region of the mantel.
  • A change in density occurs as a result of asthenosphere compression.
  • The thick and viscous material in the asthenosphere, the liquid is called viscoelastic.
  • Isostatic equilibrium is reached when areas of the lithosphere stop rising.

Therefore, Isostasy is the theory that explains how crust flote over the mantle.
