Question

question 27 of 28
isostasy is a balance of which two forces?
a. gravity and heat
b. pressure and buoyancy
c. pressure and heat
d. gravity and buoyancy

Explanation:

Isostasy is the state of gravitational equilibrium between the Earth's lithosphere and asthenosphere. The lithosphere 'floats' on the more ductile asthenosphere. Gravity pulls the lithosphere downward, while buoyancy (due to the less - dense asthenosphere) pushes it upward, creating a balance.

Answer:

D. Gravity and buoyancy
