As a tsunami enters shallow water, ____.

Question

​As a tsunami enters shallow water, ____.

BlackTom AI · Accepted Answer

When a tsunami moves from deep to shallow water, its behavior is governed by shallow-water wave dynamics. As water depth d decreases, the wave speed v = sqrt(gd) (where g is gravity) decreases, so the leading wave decelerates in the shallower region. To conserve wave energy, the wavelength shortens, and the wave's height (amplitude) increases, often producing large, breaking waves near coastlines. This explains why the statement 'the wave speed will decrease, and the height will increase' aligns with the physical shoaling process.

In this particular item, there are no alternative answer choices provided to compare against the given statement. If other options existed, we would evaluate them by checking whether they correctly describe shoaling physics (for example, claims that speed remains the same, or that height decreases, would be incorrect). The key misconception to avoid would be thinking energy conservation implies constant height or constant speed, rather than the trade-off between speed, wavelength, and height in shallow-water conditions.
