Final answer:
Three types of geological phenomena around tectonic plates are earthquakes, volcanic eruptions, and mountain formation.
Step-by-step explanation:
Three types of geological phenomena that occur around tectonic plates are earthquakes, volcanic eruptions, and mountain formation. When tectonic plates shift or collide, tremendous amounts of energy are released, causing the Earth's crust to shake, resulting in earthquakes. Volcanic eruptions occur when magma from the Earth's mantle rises to the surface through cracks in the crust. Mountain formation is another geological phenomenon that occurs around tectonic plates, where two plates collide, causing rocks to buckle and fold, creating mountains.
