Centripetal, gravitational, resultant
center of an open ocean tidal system
largest tidal range in the lunar cycle
smallest tidal range in the lunar cycle
steep wave front surging up a river as a result of tides
water moving out from an inlet due to approaching low tide
The tide-generating force is inversely proportional to the cube of the distance
The plane through the ellipse that marks the revolution of Earth around the Sun is called the ecliptic.
A lunar day is shorter than a solar day.
There is no horizontal tide-generating force on Earth at points directly below and opposite the Moon.
The Sun and the Moon have relatively equal tide-generating forces on Earth.
The barycenter follows a smooth orbit around the Sun.
All else being equal, tides have a greater range when the Moon is at apogee than when the Moon is at perigee.
A spring tide occurs once per month
A semidiurnal tide is common along the Pacific coast of the United States.
The maximum tidal range in the Bay of Fundy is about 17 meters.
The seaward flow of water due to tidal forces through an inlet is called an ebb current.
The force that pulls an orbiting body toward the center of that orbit is called:
The difference between centripetal forces and gravitational forces is called the:
The center of mass of the Earth-Moon system is called the:
The barycenter follows:
a smooth orbit around the Sun.
The tide-generating force varies:
inversely with the cube of the distance between the objects.
The tide-generating force varies:
directly with the product of the object masses.
Compared with a solar day, a lunar day is:
longer than a solar day.
The angular distance of the orbital plane of the Sun or Moon above or below Earth's equatorial plane is called the:
A spring tide:
has very high high tides and very low low tides
A neap tide has:
very small tidal range.
Spring tide occurs about:
twice per month.
Neap tides occur:
when the Moon is at quadrature.
When Earth is at its greatest distance from the Sun, it is said to be at:
The side of Earth that faces the Moon experiences a high tide, the side of Earth that is opposite from the Moon will have a(n):
The vertical difference between high and low tides is called the
Tidal ranges will be largest when the Moon is at:
The center of an open ocean tidal system is called a(n):
An area that experiences semidiurnal tides will have:
two high tides and two low tides of nearly equal height daily.
An area that experiences diurnal tides will have:
one high tide and one low tide daily.
The most common tidal pattern around the world are:
In the United States one can find semidiurnal tides along the:
In the United States one can find mixed tides along the:
The Bay of Fundy is well known for which tidal characteristic?
very large tidal range.
Water flowing out of an enclosed basin due to the tides is called:
The maximum tidal currents are reported:
about half way between high and low tides.
Tidal current can produce rotary currents called:
Which of the following is a tidal current?
both ebb tides and flood tides.
