Question

question 4 of 20 : select the best answer for the question. 4. ______ is the point where some region of the lithosphere reaches its ultimate elevation and stops rising. a. isostatic uplift b. isostatic equilibrium c. buoyancy d. orogeny mark for review (will be highlighted on the review page) << previous question next question >>

Explanation:

To solve this, we analyze each option:

• Option A: Isostatic uplift refers to the rising of the lithosphere, not the point where it stops rising.
• Option B: Isostatic equilibrium is the state where a region of the lithosphere reaches its final elevation and stops rising, as the forces (like buoyancy and gravity) balance out.
• Option C: Buoyancy is a force related to floating in a fluid, not the state of stopping elevation rise.
• Option D: Orogeny is the process of mountain - building, not the state of reaching a final elevation and stopping.

Answer:

B. Isostatic equilibrium
