Which consequence results when prolonged tephra fallout occurs?

💡 Explanation

Heavy tephra fallout blocks sunlight, inhibiting photosynthesis; therefore, widespread crop failure and famine occur because of reduced plant productivity, rather than ozone depletion or glacial melting affecting higher-latitude environments.
