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 calculation helps determine the average level of the sea over time and provides a baseline for measuring changes in sea level due to factors such as climate change. Option A is incorrect since a consistent value for mean sea level has been determined based on these calculations. Option B is also incorrect since mean sea level can vary along different parts of the coast due to factors such as geography and local ocean currents. Option D is incorrect since the sea level along the Gulf Coast is not consistently the lowest for all areas of the lower 48 United States.
