5.3 Tides And Moons Flashcards
Tidal range
Difference in levels of ocean water at high and low tide
Spring tide
A tide of increase range that occurs two times at the new and full moon
Neap tide
A tide of minimum range that occurs
What is one of the biggest tidal ranges in the world
Bay of Fundy
How long does the water levels move between high and low tides
Little over 6 hours
What causes tides
They are caused by the moons gravity pulling on the ocean
What has the largest affect on earths tides
Moon
How often does a neap tide and spring tide occur
Twice a month each
The side of Earth facing the moon will experience what tide
The lower high tide
First quarter moon means what type of tide
Neap tide
Spring and neap tides result from what
Arrangement of moon, sun, and earth in space
When the earth, sun, moon form a right angle what tide takes place
Neap
Why is the timing of tides predictable
The moons path is predictable
The gravitational pull of the moon on the water at earths surface causes what
Tides
Tide
The periodic rise and fall of the water level in the oceans and other large bodies of water
What does the moon reflect
Suns light
Lunar phases
Different appearances of the moon throughout the lunar cycle
Waxing
When the moon is getting bigger
Light to the right
Waning
Moon is getting smaller
Light to the left
How long does the lunar cycle last
28 days
Neap tides occur on what type of moons
Quarter moons
Moon is one quarter of its way through the lunar cycle
First quarter
Moon is three quarters of its way through the lunar cycle
Third quarter
The moon seems to be getting larger and we see a silver of the moons disk
Waxing crescent
When the moon is dark because it is between the sun and the earth
New moon
Moons disk is light because earth is between sun and moon
Full moon
When moon gets smaller. We only see a silver disk
Waning crescent
When the moon seems to be getting larger and we see 3/4 of the moons disk
Waxing gibbeous
When moon is getting smaller and we only see 3/4 of the disk
Waning gibbeous
What did sir Issac Newton publish in 1687
Theory on the moons pull on the earth
Low tides occur when water is pulled away from an area to create what?
Bulge
How long does it take for
The moon to revolve around the earth. What does this mean
It takes 24 hrs and 50 minutes.
This means that high tide will come 50 minutes later tomorrow then today
In a spring tide, what three things line up
Earth moon sun
What type of tide has the largest tidal range
Spring tides
When do spring tides occur
During a new and full moon
What type of tide has the smallest tidal range
Neap tide
What angle do neap tides form
90°
