Question

Select any THREE questions from the following and write a well constructed response.

1. Differentiate between the Equilbrium Tidal Theory and the Dynamic Tidal Theory in at least three ways.

2. What astronomical events have to occur to produce an exceptionally high or low tide? When does it occur? and how many times each year?

3. Using the Dynamic Tidal Theory explain why some places have extra large tidal ranges or exceptionaslly small tidal ranges?

4. Is the term tidal wave an appropriate term for a tsunami? Why?

Explanation / Answer

1.

Equilibrium Theory:

1.Equilibrium tidal theory involves in explaining the behaviour of tides with help of position and attraction. This theory uses the attraction of moon and sun in explaining tides formation.

2.This theory explains about the completely water covered Earth.

3.This is an idealized model.

Dynamic theory:

1.Dynamic theory deals with the activity of continents, shallow water, and partially enclosed ocean basins involve in the tide formation.

2.This theory explains about the continental and water covered earth.

3. This is a realistic model.

2.

Events occur during lunar perigee, in which full moon or new moon occurs during which moon nearest to the earth, leads to the formation of high or low tides. Event occurs every 411 days.
