Of the following phases of the Moon, which one is associated with the smallest tidal range?
Which of the following statements about the positions of the Earth-Moon-Sun system during a solar eclipse is FALSE?
Neap tide conditions are experienced.
Destructive interference between the solar and lunar tidal bulges occurs during __________.
Syzygy occurs during __________.

A tidal pattern with two nearly equal high tides and two nearly equal low tides per lunar day is called a __________ tidal pattern.
A tidal pattern with one high tide and one low tide per lunar day is called a __________ tidal pattern.

12 hours, 25 minutes
What would tides be like on Earth if the Moon did not exist?
Tides would occur, but the tidal range would be reduced.
In the open ocean, tidal currents follow which of the following patterns?
Water that is flowing out of a bay as a result of a change in the tides is called __________.
an ebb current
What is a tidal bore?
a true tidal wave caused by an incoming high tide that moves up certain rivers
