8.7C Ocean Tides
Ocean Tide
Daily changes in the level of ocean water.
Tidal Range
Difference in height between high and low tide.
Spring Tide
EXTREME TIDES because Moon's and Sun's gravity work together on the ocean water.
Spring Tide
Happens when the Earth, Sun and Moon are in a Line. Happens at New Moon and Full Moon. Occurs TWICE a month.
Neap Tide
Minimal tides because Moon and Sun are working against each other. NOT a big difference between high and low tides.
First Quarter Moon
NEAP Tide occurs at this phase.
Last Quarter Moon
NEAP Tide occurs at this phase.
Tidal Bulge
Oceans bulge on the side of Earth that is facing the moon because of pronounced gravitational effect, as well as on the opposite side of the Earth. big bulge = high tide no bulge = low tide
New Moon
SPRING Tide occurs at this phase.
Full Moon
SPRING Tide occurs this phase.
Gravitational Pull
The attraction between two objects due to the invisible force of gravity or the gravitational pull from the Moon that is primarily responsible for the tides that form on Earth.
Tidal Effect
The force of gravity is not uniform across an object; it is stronger on the side closer to the attracting object and weaker on the side farther from the attracting object; causes the tides.
Gravity
The force that pulls everything in the Universe towards everything else.
Tides
The steady rise and fall of the ocean water levels caused by the pull of gravity between the Earth, Moon and Sun. The moon has the biggest impact due to it's close distance.
Spring Tide
Tides with the largest daily tidal range which occur when the Sun, Earth, and Moon line up with each other.
Neap Tide
Tides with the smallest daily tidal range which occur when the Sun, Earth, and Moon form a 90 degree (right) angle. Occurs TWICE a month - at 1st quarter moon and 3rd(last) quarter moon.
Spring Tide
Very HIGH high tides and very LOW low tides. Occurs TWICE a month.
High Tide
When the tide is at its greatest elevation. Gravitational pull at its highest. Occurs TWICE per DAY.
Low Tide
When the tide level is at its lowest elevation. Gravitational pull at its lowest. Occurs TWICE per DAY.
Neap Tide
lower than normal high tides and higher than normal low tides.
