- 14Disturbance caused by the movement of energy through a medium.wave
- 15The energy that causes a wave to form.disturbing force
- 16The dominant force trying to return water to flatness after formation of a wave.restoring force
- 17What are the three factors that determine wave height and what should you do if you want higher waves?(1) Wind speed – increase the speed. (2) Wind duration – increase how long the wind is blowing. (3) Fetch – increase the fetch
- 18What all tides considered to be deep-water or shallow-water waves no matter where they are in the ocean?Shallow-water waves
- 19What all ripples considered to be deep-water or shallow-water waves no matter where they are in the ocean?Deep-water waves
- 20What all tsunamis considered to be deep-water or shallow-water waves no matter where they are in the ocean?Shallow-water waves
- 21How deep must the water be in order for a wave to be called a shallow-water wave as it travels through that depth of water?1/20 its height or less
- 22How deep must the water be in order for a wave to be called a deep-water wave as it travels through that depth of water?½ its height or greater
- 23Series of waves traveling together with leading waves dissipating and following waves forming.wave train
- 24Any wave traveling through water deeper than one-half its wavelength.deep-water wave
- 25Any wave traveling through water shallower than 1/20 its wavelength.shallow-water wave
- 26The uninterrupted distance over which the wind blows without a significant change in direction.fetch
- 27What is the bending of waves parallel to shore or toward a protrusion called?Refraction
- 28What is the bouncing back toward open water called?Reflection
- 29What type of interference is this?Constructive interference
- 30What type of interference is this?Destructive interference
- 31What does constructive interference due to the size of waves in fully developed seas, decreases the size, increases the size, or does not change the size of waves?increases the size
- 32What does destructive interference due to the size of waves in fully developed seas, decreases the size, increases the size, or does not change the size of wavesdecreases the size
- 33How does the size of a rogue wave compare to the waves around them in a fully developed sea?It is bigger
- 34Are rogue waves considered to be predictable or unpredictable?Unpredictable
- 35What causes rogue waves, constructive interference, destructive interference, diffraction, reflection, or refraction?constructive interference
- 36A heavy sea wave that breaks into white foam on the shore.breaker
- 37The bending of waves as they travel at an angle from deep water into shallow water. The path of the waves become parallel to the shore.refraction
- 38Long-wavelength wave caused by rapid displacement of water. It is always considered to be a shallow-water as it is always traveling through water less than 1/20 its wavelength.tsunami
- 39Compared to the solar tides caused by the sun, lunar tides caused by the moon are larger, smaller, or the same size?Larger
- 40What is the length of the lunar day?24 hours 50 minutes
- 41What causes tides?gravity between mainly the Earth and the moon, gravity between the Earth and the sun, and inertia

- 46Which tide has the highest high tide and lowest low tide, neap tides or spring tides?spring tides
- 47Which tide has the lowest high tide and highest low tide, neap tides or spring tides?neap tides
- 48Periodic short-term change in the height of the ocean surface at a particular place, generated by long-wavelength progressive waves, which are caused by inertia and gravitational force between mainly the Earth and the moon and to a lesser extent the Earth and the sun.tide
- 49The difference in height between consecutive high and low tides.tidal range
- 50The period between low tide and high tide during which water flows towards the shore.flood tide

- 58A tidal cycle of two high tides and two low tides each lunar day, with the high tides of nearly equal height.semidiurnal tide
- 59A tidal cycle of one high tide and one low tide per day.diurnal tide
- 60A "no-tide" point in the middle of a body of water from which tide crests rotates outward. Sometimes called a node.amphidromic point
- 61A high, often breaking wave generated by a tide crest that advances rapidly up an estuary or river.tidal bore
