Why does tsunami wave grow so high when it reaches the shore?
When a wave is traveling in deep water, its bottom is at a set depth. As it comes ashore, the wave tries to stay the same wave height. since the land is denser than the water, the water is forced upward. That upward movement is the height of the tsunami.
What is the difference between a deep water wave and a shallow water wave?
The basic differences are that the deep water wave "spreads out" and moves very quickly across open water. Wave height is not "significant" in these waves. When the wave reaches shallow water, however, it "slows down" at the leading edge. This causes the wave to "bunch up" and increase in height, even to dangerous proportions. A 20 or 30 metre high wave would devastate a shoreline, but would be hardly noticeable if it passed beneath a ship in deep water.
What part of the water is affected by a wave in deep water?
The water molecules of a deep-water wave move in a circular motion. The diameter of the motion decreases with the distance from the surface. The motion is felt down to a distance of approximately one wavelength, where the wave's energy becomes negligible.
Is it true that tsunamis are only a few feethigh in shallow water?
No. Tsunamis may only be a few centimetres high in DEEP water but as the water depth decreases the wave height increases.
What are tsumamis?
A tsumami is a large amount of water arranged into a wave. It is triggered when a large earthquake displaces a large amount of water and sends it hurling towards land. As the deep water wave gets close to land it picks up speed and gains height.
How does an ocean wave change as it moves from deep water to shallow water?
Deep water waves are long in length but short in height. As the wave moves into shallower depths it becomes shorter in length and taller in height.

When deep water waves reach water shallower than one half to their wavelength they?
The wave gains height as the top continues travelling faster than the bottom of the wave, so forming a wave crest.

How does your view of a water wave change when you are travelling at the same speed as the wave?
If the depth of the water stays the same, the wave looks the same, to a first approximation. If the water gets deeper the wave height will decrease. If the water becomes shallower, the wave height increases. A second order effect is that friction effects will slowly reduce the wave height.

No. Tsunamis may only be a few centimetres high in DEEP water but as the water depth decreases the wave height increases.
Why does the height of a wave change as it approaches shore?
When a deep-water pressure wave, such as a tsunami, caused by earthquakes or volcanic eruptions, reaches the continental shelf, it compresses the pressure wave created. When the water gets more shallow, the wave height increases; This is simple physics: the speed of the wave actually slows as it enters shallower water. This slowing causes the wave length to shorten, but the kinetic energy contained in the pressure wave doesn't decrease. Thus the peaks get taller and the troughs get deeper.
Waves begin to feel bottom when water depth is?
One-half the deep-water wave length.
A wave moving in water that is deeper than half its wavelength is called what?
A deep-water wave.
What are tsumamis?
A tsumami is a large amount of water arranged into a wave. It is triggered when a large earthquake displaces a large amount of water and sends it hurling towards land. As the deep water wave gets close to land it picks up speed and gains height.
A wave with a wavelength of two meters forms in water with a dept of twenty meters What type of wave is it?
deep water
