Water falling to its lowest level and receding from the shore.
Explanation
Tides are the rhythmic rise and fall of ocean water that occur generally twice a day. This vertical movement of water is primarily caused by the strong gravitational attraction exerted by the sun and the moon on the earth’s surface.
Detailed Analysis:
- High Tide: When the water rises to its highest level and covers much of the shore, it is referred to as high tide. This phase is characterized by the "flow" of water toward the coast.
- Low Tide: When the water falls to its lowest level and recedes from the shore, it is referred to as low tide. This phase is characterized by the "ebb" of water away from the coast.
- Therefore, the description of water falling to its lowest level and receding corresponds to low tide.
Key Takeaway:
The vertical rise of ocean water is termed High Tide (flow), while the fall and receding of water is termed Low Tide (ebb).
