Answer:

  • (b) Volcanoes do not have air circulation but pyroclastic flow occurs at the time of eruption that moves at speeds as high as 200 m/s.

  • (c) Cyclones formed rapid inward air circulation around the low-pressure area.

  • (d) Hurricane formed closed inward air circulation around the low-pressure area.
