Answer :
Internal earth heat generates geological hazards such as earthquakes, volcanoes, and tsunamis; thus, the correct answer is 'A. geological'.
Internal forces generated by the internal heat of the earth create geological hazards like earthquakes, volcanoes, and tsunamis. Endogenic forces, originating from inside the Earth and its heat engine, are responsible for these types of events. On the other hand, external forces arising from solar radiation lead to weather-related and climatic events, such as flash floods and hurricanes. The appropriate answer to the student's question is therefore 'A. geological' hazards.
