How do tides on Earth relate to the Moon’s phases?

Tides on Earth are significantly influenced by the Moon's phases due to the gravitational pull exerted by the Moon. The relationship between the Moon's phases and tides can be best understood through the concept of gravitational attraction.

Gravitational Pull:

During the lunar cycle, the Moon's gravitational pull on Earth causes the oceans to bulge towards the Moon. As a result, we experience high tides in the areas facing the Moon and low tides in the areas perpendicular to it. This gravitational force creates two high tides and two low tides every approximately 24 hours and 50 minutes, which corresponds to the Moon's daily passage overhead.

Tidal Patterns:

As the Moon goes through its phases – new moon, first quarter, full moon, and last quarter – the alignment of the Sun, Earth, and Moon changes. During a new or full moon, when the Sun, Earth, and Moon are in alignment, we experience higher high tides and lower low tides known as spring tides. Conversely, during the first and last quarter moons, when the Sun and Moon form a right angle with Earth, we observe lower high tides and higher low tides called neap tides.

In conclusion, the varying gravitational pull of the Moon during its phases directly impacts the tidal patterns on Earth, leading to the rhythmic rise and fall of ocean levels that we experience daily.
