21
Q

Neritic location

A

covers continental shelf

shallow

22
Q

Oceanic location

A

covers entire sea floor except continental shelf

23
Q

Neritic characteristics

A

warm and shallow
largest concentration of marine life
receives more sunlight

24
Q

Oceanic characteristics

A

deep- temperature cold and pressure high

organisms spread out

25
Q

Neritic organisms

A

fish. plankton, other marine animals

26
Q

Oceanic organisms

A

giant squids, some whale species

27
Q

Wave height

A

the vertical distance between the crest and the trough

28
Q

Wavelength

A

the distance between two crests or two troughs

29
Q

Wave period

A

the time it takes for one wavelength to pass a given point

30
Q

Waves are caused by…

A

wind and the shape of the ocean floor

31
Q

_______ transfers ________ from air to water molecules through_______

A

wind transfers energy from air to water molecules through friction

32
Q

Waves of water only move….

A

up and down, not horizontally

33
Q

Particles in the wave move in a ________ motion

A

circular motion

34
Q

What is a breaker?

A

where the bottom of the wave hits the ocean floor and the top keeps moving, forming an arc
(wavelength shortens and height increases as bottom of wave interacts with ocean floor)

35
Q

Waves start at an _______ with the wind, and ____________ to become ________ with the shore when breaking

A

waves start at an angle with the wind, and slow down to become parallel with the shore when breaking

36
Q

Longshore Current

A

waves strike shore at an angle, causing a current to flow parallel to the shore

37
Q

How do rip tides form?

A

when a sandbar is broken apart, causing water to rush back to sea

38
Q

What is a tsunami

A

Waves that form when a large volume of ocean water is suddenly moved up or down- usually generated by an earthquake

39
Q

What causes tides

A

The pull of gravity between the earth sun and moon

40
Q

Does the sun or moon have a greater influences on the oceans

A

Moon because it’s closer

41
Q

Spring tide

A

Occurs twice a month at full and new moon

Highest high tide and lowest low tide

42
Q

Neap tide

A

Occurs twice a month at first and last quarter

Causes low high tide and high low tide
