Which of the following is CORRECT regarding mean sea level?
A)A consistent value has yet to be determined due to all the variables involved in producing the tides.
B)It is calculated based on average tidal levels recorded hourly at a given site over a period of many years.
C)It is at the same level along the entire North American coast.
D)It has very little variability across all ocean basins and,therefore,is treated as an absolute value.

Question

Quizplus · Accepted Answer

Mean sea level is calculated based on average tidal levels recorded hourly at a given site over a period of many years. This allows for fluctuations in tides and other variables, providing a consistent reference point for measurements related to sea level. Option A is incorrect as a consistent value for mean sea level has been determined through this method, and option C is incorrect as mean sea level can vary along different coastlines due to factors such as ocean currents and land elevation. Option D is also incorrect as there is variability in mean sea level across different ocean basins.
