Answer:
B. every 12.5 hours
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Hence, tides are the cycle of rising and falling ocean water that repeats approximately every 12.5 hours.
