Why would ship wrecks be preserved better in deeper water than shallower water?
Shipwrecks are better preserved in deeper water because deeper waters have stable temperatures, lower oxygen levels, and reduced light, which slows down the decay process. Also, deep-water environments are less disturbed by natural phenomena like currents and waves, which can break down wrecks in shallower waters.
Can deep-water and shallow-water waves exist at the same point offshore?
Yes, deep-water and shallow-water waves can exist at the same point offshore. In areas where the water depth changes gradually, both types of waves can coexist in the same location. Deep-water waves occur in deeper waters where the water depth is greater than half the wavelength, while shallow-water waves occur in shallower waters where the water depth is less than half the wavelength.
How does wave refraction result in sediment deposition in some shoreline area?
In deeper water offshore, incoming waves move at constant speed, but they slow down in shallower waters. As an incoming wave approaches the shoreline at an oblique angle, the part of the wave in shallower water will have a lower speed than the part in deeper water. These different speeds for different parts of the same wave cause the wave to refract (bend). In general, wave refraction rotates obliquely incoming waves toward parallelism with the coastline. Over time, headland erosion and deposition in protected bays and coves tend to even out irregularities, thus straightening the coastline.

How do waves change their approach the shore?
As waves approach the shore, they experience shoaling which causes them to slow down and increase in height. This is due to the decrease in water depth and the wave energy becoming compressed. The waves then break as they reach shallower waters, eventually dissipating their energy on the shore.
When deep water waves reach water shallower than one half of their wavelength they become what water waves?
When deep water waves approach water shallower than half their wavelength, they are transformed into shallow water waves. These waves have shorter wavelengths and slower speeds due to interacting with the sea floor, causing their amplitudes to increase as the water becomes shallower.
How does refraction cause wave crests to move when the waves approach the shore?
Refraction of waves at the shore causes wave crests to bend and align more parallel to the coastline. This happens because the part of the wave in shallower water slows down, while the deeper part continues at a faster speed, resulting in the wave crest bending toward the shallower area.
Where do water waves become shallow water waves?
when waves reach shallower the one half their wave length they begin to interact with the ocean floor
Where the waters wind?
the waters wind is in the tides waves
How high are tsunami waves in deep water?
In deep water, tsunami waves typically have a wave height of less than a meter and are often barely noticeable. However, they can travel at speeds of up to 500-800 km/h (310-500 mph). As the waves approach shallower coastal waters, they can increase significantly in height, sometimes reaching dozens of meters.
What characteristic of waves increases as they hit the coastline?
Amplitude. The wavelength decreases accordingly. Waves travelling through deep water - even tsunami waves, can have a surprisingly low amplitude (height) of just a few cms, but a very low frequency and long wavelength. They can travel fast too. But as they come into shallower water the wavelength drops and as a consequence the amplitude rapidly increases, creating the much larger waves we see on the shore itself.
What do you call the change in direction of a wave at a boundary?
The terminology is the same for all waves, including light - so reflection or refraction depending on what you mean by change of direction. Firstly thanks for answering, I meant if you had water waves travelling from deeper to shallower water. The wavefront change direction when entering the shallower. so http://wiki.answers.com/Q/What_do_you_call_the_change_in_direction_of_a_wave_at_a_boundary" The effect is the same as bending of light as it goes from air into glass, for instance, it is refraction.
