Final answer:
Tectonic motion involves continental plates plunging beneath oceanic plates, volcanic eruptions releasing hot gases, and hot spots forming multiple volcanoes due to plate motion.
Explanation:
Correct statements regarding tectonic motion:
- Continental plates plunging beneath oceanic plates during a collision is correct.
- A volcanic eruption releasing hot gases into the air is correct.
- A single hot spot forming multiple volcanoes due to plate motion is correct.
Earthquakes being the most common cause of tsunamis and seafloor spreading occurring at convergent boundaries are incorrect statements about tectonic motion.
