Tides
The number of high tides a region generally experiences within 24 hours?
What is two?
Caused by wind direction and the Coriolis effect, causes the garbage patches in the ocean.
What is a gyre?
Distance from one wave crest to another wave crest is called this.
What is wavelength?
Water activity produced primarily by gravity.
What are tides?
Contains large amounts of energy.
What are tides?
A lower-than-usual tide caused when the sun, earth, and moon are at right angles.
What is a neap tide?
Narrow, fast currents that flow offshore through gaps in offshore bars are called this.
What are rip currents?
A wave that becomes unstable and breaks form is called this.
What is a breaker?
A sandy strip of land that extends from the shore across part of a bay.
What is a spit?
Ocean navigation is most affected by this.
What are currents?
The greatest influence in causing tides.
What is the moon?
Currents that flow parallel to the shore are called this.
What is longshore current?
What is wave height?
Terms for the depositing of sand and the removal of sand from a beach through wave action.
What is wave deposition and wave erosion?
The rule governing when a wave becomes unstable and crashes down into itself, forming a breaker.
As the earth spins, water is pulled by the moon, causing this.
What is a tidal bulge?
Occurs when seawater piles up, as in the middle of a gyre or against the shore.
What is downwelling?
The distance that a wind blows over the water's surface in one direction as a wave forms is called this.
What is fetch?
A spit of land that eventually grows across a bay's mouth, closing it to the sea.
What is a barrier?
What are groins?
A higher-than-usual tide that occurs when the sun, moon, and earth form a right angle.
What is a spring tide?
What is thermohaline current?
Carries nutrients from deep water to the ocean surface.
What is upwelling?
A combination of the Coriolis effect, wind speed, and water depth.
What is the Ekman spiral?
Occurs when seawater is blown or dragged away from a region of the ocean, lowering the sea level below average.
What is upwelling.
