Question

which best describes a tsunami?
o large powerful wave caused by an earthquake
o when the waves hit the shore at an angle and transport sand
o alternating rise and fall of the ocean
o an irregular climate event caused by ocean currents in the pacific ocean

Explanation:

A tsunami is a large and powerful wave. It is typically caused by an earthquake (or other seismic activity like volcanic eruptions or landslides) under the ocean. The second option describes longshore drift (not a tsunami). The third option describes tides. The fourth option describes El - Niño (an irregular climate event).

Answer:

large powerful wave caused by an earthquake
