Question

what forces generate tsunamis? what forces generate tsunamis? tidal forces are much weaker than earthquakes. tsunamis are driven by seismic waves. earthquakes trigger tsunamis by displacing large amounts of rock and sediment on the ocean floor along the fault line. earthquakes generate blasts of air upward that cause waves like ripples on a pond, which are known as tsunamis.

Answer 1

Answer:Tsunamis are primarily generated by seismic forces, specifically large undersea earthquakes that displace large amounts of water. When an earthquake occurs, it can cause the seafloor to rise or fall, displacing a large volume of water. This displacement generates waves that spread out in all directions from the epicenter of the earthquake, much like ripples on a pond. These waves can travel across entire ocean basins, and as they reach shallow water near the coast, they can grow in height and cause significant damage.

Other events that can generate tsunamis include underwater landslides, volcanic eruptions, and meteor impacts. However, these events are much less common than earthquakes as a cause of tsunamis.

Tidal forces, while they can cause significant changes in ocean levels, are not a significant cause of tsunamis. Similarly, the idea of earthquakes generating blasts of air that cause tsunamis like ripples on a pond is a misconception; tsunamis are primarily driven by the displacement of water due to seismic forces.
