Answer:
gravitational force, low tide.
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.
Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.
This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
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, the gravitational force pulls on the water facing the moon creating a low tide.
Additionally, tides are caused by the cycle of rising and falling ocean water that are repeated approximately every 12.5 hours.
