What is ebbs and flows?

The ebb and flow phenomenon, also known as tidal flow, refers to the periodic rise and fall of sea levels caused by the gravitational forces of the Moon and the Sun acting on the Earth. This creates a cycle of high tide and low tide.

Here's a breakdown of key aspects:

• Causes: The primary cause is the gravitational pull of the Moon on the Earth's oceans. The Sun also contributes, but to a lesser extent because of its greater distance. The gravitational force is strongest on the side of the Earth facing the Moon, creating a bulge of water (high tide). A corresponding bulge occurs on the opposite side of the Earth due to inertia.
• Tidal Bulges: As the Earth rotates, different locations pass through these tidal bulges, experiencing high tides. The areas between the bulges experience low tides.
• Tidal Cycle: Typically, most coastal areas experience two high tides and two low tides each day. This is known as a semi-diurnal tide. Some areas have diurnal tides (one high and one low tide per day) or mixed tides (varying heights and intervals).
• Spring Tides and Neap Tides: The alignment of the Sun, Moon, and Earth significantly influences tidal ranges. When the Sun, Moon, and Earth are aligned (during new and full moons), their gravitational forces combine to produce higher high tides and lower low tides, known as spring tides (not related to the season). When the Sun and Moon are at right angles to the Earth (during the first and third quarter moons), their gravitational forces partially cancel each other out, resulting in smaller tidal ranges known as neap tides.
• Factors Affecting Tides: Besides the Moon and Sun's gravitational forces, other factors like coastal geography, ocean currents, and the shape of the seafloor can influence tidal patterns. Coastal geography has a huge impact on tides.
