Exam 9: Tides

Grunion depend upon a tide-related pattern of erosion and deposition of sand for the survival of their eggs.

Water flowing out of an enclosed basin due to the tides is called a/an:

Compared with a solar day, a lunar day is:

A spring tide occurs once per month.

The barycenter follows:

The angular distance of the Sun or the Moon above or below the Earth's equatorial plane is called the:

-Discuss the influence of the relative masses and distance between the two objects on tide-generating forces.

The vertical difference between consecutive high and low tides is called the:

Spring tide occurs about:

Match the term with the appropriate phrase. You may use each answer once, more than once or not at all. -resultant

Tidal ranges are much greater during apogee than perigee.

If the resultant force has a significant horizontal component (tangential to Earth's surface), it produces tidal bulges on Earth, creating what are known as:

The tide-generating force varies:

An area that experiences semidiurnal tides will have:

The Sun and the Moon have relatively equal tide-generating forces on Earth.

-Describe the tides in an open-ocean basin.

The most common tidal pattern around the world are:

-Briefly describe why the Sun's influence on Earth's tides is only 46% that of the Moon, even though the Sun is much more massive that the Moon.

-How do centripetal forces and gravitation forces interact to produce the tides?

The barycenter follows a smooth orbit around the Sun.
