Use the information below to answer the question(s) below: The Hawaiian Islands are home to some of the most studied volcanoes on Earth. The volcanoes erupt often but are seldom explosive because of the magma that they produce. Kilauea volcano is located on the largest of the Hawaiian islands and rises over 4,200 feet above sea level. Kilauea has been erupting continuously since 1983 and has resulted in new landmass. Which event is best explained by tectonic plate movement? A. a tornado B. a tsunami C. a hurricane D. a thunderstorm E. tides

B. a tsunami

In the United States, most tornadoes are classified as intense A. low-pressure funnel clouds that spin clockwise B. low-pressure funnel clouds that spin counter-clockwise C. high-pressure funnel clouds that spin clockwise D. high-pressure funnel clouds that spin counterclockwise

B. low-pressure funnel clouds that spin counter-clockwise * In the Southern Hemisphere, tornados typically spin CLOCKWISE. This difference is due to the "Coriolis Effect"

C. undersea earthquakes

Faults that occur when tectonic plates come together/collide with each other.
