tides

Spring tides

Occurs when the sun, moon, and Earth are aligned, creating the greatest tidal range.

Neap tides

Occurs when sun and moon are at right angles, creating the smallest tidal range.

Tidal bore

A single wave that forms when incoming tide reverses a river flow, flows up a river.

Semi-diurnal tide

Two high tides and two low tides of equal range in 24 hours.

Mixed tide

Two high tides and two low tides of unequal range in 24 hours

Swells

Waves formed far away, not by local winds.

Capillary waves

Small waves caused by surface tension

Intertidal Zone

Area exposed at low tide and submerged at high tide.

Plunging breaker

A steep slope causes the crest to curl and break violently.

Rogue wave

Extremely large, unexpected wave often formed by interacting swells and currents

Why does the moon have a stronger influence on the earth, than the sun, causing tides?

The moon is much, much closer to the earth than the sun, causing a greater gravitational pull on the earth and ocean

How often do neap or spring tides occur?

Every 14 days

Waxing moons are when the moon is?

Growing

Wanning moon is when the moon is?

Shrinking

Ebb of tides

When the tide goes out

Flow (flood) tides

When the tide comes in

FETCH

Distance of open water the wind travels over from one body of land to another

Surging breaker

a type of ocean wave that rushes up a very steep beach face without fully curling or dissipating much energy

Spilling breaker

Ocean floor has a gradual slope, white water foam gently “spills” down the face of the wave
