A tsunami is a:

Correct option is C

A tsunami is a type of surface wave that combines characteristics of both transverse and longitudinal waves. Tsunamis are generated by undersea disturbances like earthquakes, volcanic eruptions, or landslides. Here's how the wave dynamics work:
1. Longitudinal motion: Particles in the water move back and forth in the direction of wave propagation (compression and rarefaction).
2. Transverse motion: Particles also move perpendicular to the direction of wave propagation (up and down).
Information Booster: · Tsunamis travel at high speeds in deep water, often exceeding 500 km/h.
· They grow in height as they approach shallow coastal areas due to wave shoaling.
· Unlike wind-driven waves, tsunamis involve the entire water column, from surface to seabed.
· The energy of a tsunami comes from the displacement of massive volumes of water.
· Tsunamis can cause widespread destruction when they hit coastal areas.
