Slide1

Tides

Slide2

Gravitational forces between two objectsproduce tides

Slide3

Gravitational pull of the moon and sunCentripetal force of the rotating Earth

Tides are generated by:

Slide4

Slide5

Tides are generated by:

the

gravitational pull

of the

moon

and

sun

- moon has 2x greater gravitational pull than the

sun

- sun is 10 million x more massive than the

moon and is 390 times farther away

Slide6

CENTRIPETAL

Slide7

High water:

a water level maximum ("high tide")

Low water:

a water level minimum ("low tide")

Tidal range:

the difference between high and low tide

Spring Tide:

full moon and new moon (14.77 days)

Neap Tide

: 1

st

quarter and 3

quarter (14.77 days)

Description of tides

Intertidal zone

High tide

Low tide

Slide8

Slide9

The monthly tidal cycle(29½ days)

About every 7 days, Earth alternates between:

Spring tide

Alignment of Earth-Moon-Sun system (syzygy)

Lunar and solar bulges constructively interfere

Large tidal range

Neap tide

Earth-Moon-Sun system at right angles (quadrature)

Lunar and solar bulges destructively interfere

Small tidal range

Slide10

Synodic PeriodA synodic period is also known as the time it takes for the moon to change from one high tide to

another high tide

.

Slide11

Slide12

Slide13

Earth-Moon-Sun positions and the monthly tidal cycle

Spring Tide

Highest high tide and lowest low tide

Neap Tide

Moderate tidal range
