Semidiurnal tides occur when a coastline on Earth experiences two high and two low tides of about the same height each day.
Explanation:
If the earth did not have continental, then the predominantly tides would be diurnal tides. This means there would be one high and low tide at a point in the ocean. However, the presence of continents causes the tides to vary across coastal regions of different continents -mixed. This is because the ocean waters are not free-flowing with the moon’s and sun’s gravitational pull. The blockage by continentals to this flow causes mixed diurnal and mixed semi-diurnal tides. Mixed semi-diurnal tides have two high and low tides of unequal amplitudes on a lunar day.
