What is the condition of equilibrium or balance in a system called? Geologists often use this term to describe crustal blocks floating on the asthenosphere.
A) isostasy
B) convection
C) Curie point
D) geothermal gradient
Isostasy
The condition of equilibrium, comparable to floating, of the crust resting on the solid mantle.
Equilibrium
A state of balance between opposing forces or actions.
Asthenosphere
The area of mantle beneath the lithosphere that is solid, but hotter than the rock above it and can flow under pressure; functions as a soft, weak zone over which the lithosphere may move.

Final Answer :
A
Explanation :
Isostasy refers to the equilibrium or balance of the Earth's crust, where the crust floats on the denser, more fluid asthenosphere beneath it. This concept explains how different topographic heights are supported by variations in crustal thickness and density.
