The figures below show the swell and winter profiles for the same beach. Which of the profiles (A or B) is the winter profile and what features characterize it as such?  

The following figure shows the variation in sea level at an example coast over one day. What type of tidal pattern does this coastline experience?

What is the speed of a shallow water wave, in meters per second, if the ocean is 1 meter deep and the wave has a wavelength of 20 meters? Shallow-water wave:

The Sun exerts the greatest tide generating force because it has more mass than the Moon. 

Threats can be categorized in many ways; they can be human-made or natural, accidental or intentional, internal or external, and so on.
