3. The most dangerous geologic hazards are A. earthquakes B. hurricanes C. volcanoes D. landslides E. all of the above

most dangerous geologic hazards are earthquakes

Explanation:

most dangerous geologic hazards are earthquakes

because

we know that Geological hazards occur because of geological processes that is movement in the tectonic plates and the volcanic activity

and due to movement of tectonic plate it generate the earthquake, landslide and volcanic etc

so here earthquake is more danger and hazards because volcanic and landslide most come in hilly area and density of people is more in plane surface as compare to hilly area

so most dangerous geologic hazards are earthquakes
