INDIAN GEOGRAPHY

Detailed explanation-1: -This occurs because the moon revolution around the earth has the same direction as the earth’s rotation. Therefore, it takes extra 50 minutes for the earth to catch up with the moon. So, there will be two tidal bulges and we experience two high and two low tides every 24 hours 50 minutes.

Detailed explanation-2: -A diurnal tidal cycle is characterized by a single high tide every 24 hours and 50 minutes (Fig. 6.16 C). Diurnal tides typically occur in partially enclosed basins, such as the Gulf of Mexico (Fig. 6.17).

Detailed explanation-3: -In most places on the planet, high and low tides occur twice daily. Each day these tides change 50 minutes later, as it takes the moon 24 hours and 50 minutes to completely rotate around the earth.
