ocean waves Flashcards
Ocean Wavesare ? in the ? of theocean.
They can be created by ? ? ?
Ocean Wavesare disturbances in the surface of theocean.
They can be created by wind, gravity, or other displacements of water.
The motion of water particles in a wave is ？.
After a wave passes the water particles return to position.
T
he motion of water particles in a wave is circular.
After a wave passes the water particles return to basically the same position.
The circular motion of water extends beneath the ?
As depth ?the circular motion ?.
The circular motion of water extends beneath the surface.
As depth increases the circular motion decreases.
A surface wave becomes a ? when it collapses near the ?.
A surface wave becomes a breaker when it collapses near the shore.
tsunami is a wave that forms when an ? suddenly moves a large volume of ?.
tsunami is a wave that forms when an ocean disturbance suddenly moves a large volume of water.
tsunami can be caused by an ????
tsunami can be caused by an underwater earthquake, a volcanic eruption, landslides, or breaking glaciers.
Surface zone:
Surface zone: area with the greatest amount of sunlight, shallow water.
Middle zone
Middle zone barely any sunlight.
Deep zone ?do not grow in this zone. Most deep sea animals create their own light in a process called .
Deep zone there is no light. Plants do not grow in this zone. Most deep sea animals create their own light in a process called bioluminescence.
Oceans also have layers of ??? which all vary with depth.
Changes in these characteristics can create ?
Oceans also have layers of temperature, salinity and density which all vary with depth.
Changes in these characteristics can create distinctive layers of seawater.
depth increases the water in ?regions cools rapidly.
Temperature of ? water remains constant.
depth increases the water in temperate and tropical regions (warm) cools rapidly.
Temperature of polar (cold) water remains constant.
Warm water in tropical and temperate regions are ?ier than polar regions.
Warm water in tropical and temperate regions are saltier than polar regions.
water is denser than water. temp
water is denser than water.salinity
Cold water is denser than warm water.
Salt water is denser than fresh water.
