It is a process known as shoaling. When waves feel the bottom they slow down and decrease their wavelength but the period of the waves does not change. The height of the wave will steadily increase until the wave becomes unstable and breaks near the beach.

Is it true that an earthquake on the ocean floor can produce a tsunami which may grow into a huge wave as it approaches the shore?
true
How does wave action cause changes in a coastline?
Waves shape a beach by eroding the shore in some places and building it up in others. ♥
If a coast guard warns of a giant wave of water approaching the shore as a result of a major earthquake what are they warning of?
If the Coast Guard warns of a giant wave of water approaching the shore as a result of a major earthquake, they are warning of...... a tsunami
How do waves even out the shoreline?
Waves even out a shoreline by eroding it.The waves coming to shore gradually change direction, as different parts of the wave begins to drag the bottom.The energy of the wave is concentrated on headlands, part of the shore that sticks out into the ocean.As waves erode the headlands the shoreline will eventually even out.Tee Hee!!!!!!!!!!!!!!!!!!!!!!!! ___------ -/---- ----\/--- --- \------------ ---- --
Do waves occur before or after an earthquake?
waves occur all the time but after an earthquake tidal waves occur. Tidal waves are the cause of the tectonic plates colliding underwater. After the collision over time the wave goes form a small bump in the water to growing bigger and bigger into giant super wave capable of destroying towns.
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.
When a wave approaches the shore it moves ahead of its?
Breakercrest
What is the crest of this giant wave approaches shore sea level appears to rise?
It is aclled an high tide
Can breakers form before the wave approaches the beach?
Of course it can. That is why some waves don't reach the shore.
How both a wave's energy and the water in a wave move?
Ocean water within a wave moves in a circular motion in open water. As the wave approaches the shore, the water becomes shallow and the bottom.
Is it true that an earthquake on the ocean floor can produce a tsunami which may grow into a huge wave as it approaches the shore?
true
As a wave approaches shore what happens to wave height and wavelength?
Depending on height at origin as it approaches the coastal shelf it will rise and increase the strength of the wave. for example a wave 50ft high approaching the atlantic coastal shelf could rise to 150-200 feet with disastrious ramifications.
Why do these changes occur when a tsunami wave is approaching the shore?
because earth is moving and when we move sometimes mostly everything moves with earth and it goes different ways everyday of an year
How does a wave eventually even out the shore line?
As it approaches the shore the energy moving through the water meets the shallows resistance. It collapses into the wave you see at the beach. This energy can smooth out the beach with the help of tidal variation. Make rocks into sand.

What are the changes that occur in wave energy at headlands?
Laminar flow compession
