Question

a series of powerful, long - wavelength waves caused by large - scale displacement of water (tsunamis) are ____. capillary waves swells seismic waves tides

Explanation:

• Capillary waves are small - scale waves caused by surface tension, not related to large - scale water displacement.
• Swells are long - wavelength waves, but they are not specifically associated with large - scale water displacement (tsunamis).
• Seismic waves are waves caused by seismic activity (earthquakes, etc.), and tsunamis (which are a series of powerful, long - wavelength waves caused by large - scale displacement of water) are a type of seismic sea wave.
• Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans, not by large - scale water displacement in the sense of tsunamis.

Answer:

seismic waves
