Final answer:
When the Moon is deep under the horizon in the North, the region would typically be experiencing low tide, as the Earth rotates away from the tidal bulges caused by the Moon's gravitational pull.
Step-by-step explanation:
If the Moon is deep under the horizon in the North, then it means that you are located at a place where the tidal bulge caused by the Moon is currently not present. Since the Earth experiences two high tides and two low tides each day due to the rotation of Earth carrying any given observer through regions under or opposite the moon (where water is deepest) and away from these regions (where water is not as deep), it is possible to infer that if the Moon is under the horizon, you would be experiencing low tide. This is because the observer would be moving away from the deeper water region opposite the Moon, toward a region of shallower water.
Anyone living near the sea understands the twice-daily rising and falling of the tides. The tide's behaviour is closely connected to the position of the Moon relative to Earth due to the forces of gravity. Consequently, when the Moon is beneath the horizon, the portion of Earth you are on is rotating away from the tidal bulge, leading to low tide.
