The answer is:

  • Erosion
  • Burial by younger rocks
  • Disruption by faulting

Explanation for each option:

  1. Further collapse into the emptied magma chamber: This option is not typically a way in which older calderas become harder to recognize. While further collapse can occur, it usually makes the caldera more pronounced rather than harder to recognize.

  2. Erosion: This is a correct option. Over time, natural weathering and erosion can wear down the features of a caldera, making it less distinct and harder to recognize.

  3. Burial by younger rocks: This is a correct option. When newer volcanic activity or sedimentation covers the older caldera, it can become buried and thus harder to identify.

  4. Disruption by faulting: This is a correct option. Tectonic activity can disrupt and deform the structure of a caldera, making it more difficult to recognize its original shape and features.

Summary: Older calderas typically become harder to recognize due to erosion, burial by younger rocks, and disruption by faulting.

From the top of a sphere of radius r a point mass m glides smoothly down (no friction). At what height does it detach itself from the surface of the sphere? Hint: the component of the gravitational force pointing towards the center of the sphere acts as centripetal force which is mv^2 / r for a circular path with radius r and velocity v. Furthermore, potential energy is transformed into kinetic energy. Combining these two conditions leads to the solution.
