Which of the following would be evidence that a volcano has NOT been active for a long period of time?


AA layer of ash blanketing hillslopes
BRelatively unweathered lava flows
CWell-developed soils on volcanic rocks

Verified Answer :

Final answer:

A volcano that has not been active for a long time will likely have well-developed soils on its volcanic rocks, indicating stability. In contrast, a layer of ash and unweathered lava flows suggest recent volcanic activity. Therefore, well-developed soils provide evidence of prolonged inactivity.


Explanation:

Understanding Volcano Activity


To determine whether a volcano has NOT been active for a long period of time, we need to analyze the physical characteristics of the surrounding landscape.



  • A layer of ash blanketing hillslopes would suggest recent volcanic activity, as ash is typically the result of an eruption.

  • Relatively unweathered lava flows indicate that the lava is recent and has not been exposed to significant erosion or weathering, suggesting the volcano may still be active.

  • Well-developed soils on volcanic rocks indicate a long period of stability and lack of activity, as soil formation takes time and is interrupted by eruptions.


Thus, the correct answer is well-developed soils on volcanic rocks, as this indicates that the area has not experienced recent eruptions, allowing time for soil to form.
