The correct answer is - tidal patterns.
The tidal patterns are the rising of the ocean waters and the retreating of the ocean waters. The reason for this is the effect that the Moon's gravitational pull has on the Earth's water. The tides come in two forms, high tide, and low tide. The high tide is when the water is rising and goes deeper into the land, while the low tide is when the water is retreating towards the ocean. The difference between the highest point of the high tide, and the lowest point of the low tide is the tidal range.
