A wave generated in deep water, when reaching shoaling waters, charges not only in its height but also in its length but the period will decrease, this phenomenon is known as what?
Wave shoaling
True or False
When a wave generated in deep water enters shallow water, the wave encounters a change in water depth which causes the wave to slow down.

However, the period of wave, which is the time it takes for one complete wave cycle to pass a given point, will decrease. This is because the speed of the wave is directly related to the water depth, and as the water depth decreases, the wave speed decreases as well. Since the period of the wave is determined by the wave speed and wave length, a decrease in wave speed results in a decrease in wave period

Mushy waves

Spilling waves
When waves pass over a steeply inclined or rugged ocean floor, the crest of the wave curls and trap a pocket of air underneath it
Plunging waves
They are produced when huge swells reach shorelines having a steep profile
Surging waves

Collapsing waves
_, as the name suggests, have their own origin where the depth of the water in the ocean is significant
Deepwater waves
These waves have their origin where the depth of the water is much lesser

Tidal waves
_, is a Japanese word, as Japan is possibly the country most frequently affected by _
Tsunamis
The length of these waves is less than the depth of the water they enter, which decreases the velocity of the waves
Inshore waves
They are one of the largest waves in the ocean but are barely noticeable on the surface due to their formation in the internal layers of the water
Internal waves
These are large scale waves, which are caused by a lack of wind flow in the Pacific Ocean
Kelvin waves
For a _, the amplitude is equal to overall points and has net energy flow
Progressive wave
_ closely resemble ripples in their structure
Capillary waves
_ travel in shallow water when they approach the shore and the shallowness decreases the power of the wave and causes a curve
Refracted waves
_ or simple a seiche (pronounced ‘saysh’) are standing waves that form in a confined or partially confined body of water
Seiche waves
