What slows water at the bottom of a wave near shore?
Friction with the sea bed/shore
When wave come near the shore they speed up?
Yes
What happens to this wave as it reaches shore?
Since we don't know what "this wave" is, we cannot answer the question.
Where are tsunamis higher in the middle of the ocean or near shore?
Higher near shore. The land is denser than the water so the wave is higher.
What happens to a wave that encounters a gap in a cliff along the shore?
It diffracts
What happens to tsunami's as they move toward shore?
Their wave size increases.
Name and describe two kinds of currents that wave action can cause near shore?
Two kinds of currents that wave action can cause near shore are "Longshore Current", which is the overall direction and movement of the waves that strike the shore at an angle. The other kind of current is "Rip Currents", which are narrow streams of water that break through sandbars and drain rapidly back to sea.
How does the speed of the tsunami wave change as it approaches the shore?
The wave would slow down as it approaches the shore.
How does the speed of tsunami wave change as it approaches the shore?
The wave would slow down as it approaches the shore.
How do rocky shore creatures react to the wave actions?
fish on the rocky shore depend on the wave action for nutrients
How are large waves created near shore?
The large water waves created near the land's shore are caused from fast moving, but small-amplitude waves created deeper in the ocean. Conceptually, the velocity of a water wave in deep water is dependent on its wavelength. As the wave nears the shore, its wavelength gets smaller and smaller, therefore its velocity gets slower and slower. Well, a wave's velocity multiplied by its energy density is a constant, so if the velocity of a water wave gets smaller, its energy density must get larger. This increase of energy density is seen as an increase in the height of the wave.
what wave refracts?
an ocean wave approaching the shore at an angle
