Helioseismology probes solar interior structure by analyzing oscillation modes of the photosphere.

  1. True - reveals convection zone depth/radiative zone rotation
  2. False - only studies surface
  3. True - but only for flares
  4. False - requires spacecraft

Answer: True - reveals convection zone depth/radiative zone rotation
