Question

select the best answer for the question. 11. which type of stress is a uniform stress that doesnt lead to earthquakes? a. tension b. compression c. lithostatic pressure d. shear stress

Explanation:

To solve this, we analyze each option:

• Option A (Tension): Tension stress pulls rocks apart and can lead to earthquakes (e.g., normal faults), so it's not uniform in a way that avoids earthquakes.
• Option B (Compression): Compression pushes rocks together and can cause earthquakes (e.g., reverse faults), so it's not the answer.
• Option C (Lithostatic pressure): Lithostatic pressure is uniform stress from overlying rock layers, acting equally in all directions. It doesn't cause the shear or differential stress needed for earthquakes.
• Option D (Shear stress): Shear stress involves forces sliding past each other, which is a major cause of earthquakes (e.g., strike - slip faults).

Answer:

C. Lithostatic pressure
