Question
How often do ocean tides occur in a single day due to
the gravitational pull of the sun and moon?Solution
The gravitational forces of the sun and moon result in the ocean's semi-diurnal tides, which cause the water levels to rise and fall twice within a 24-hour period. This cycle includes both high tides and low tides.
