1 Ιαν 2023 · Although submarine eruptions at mid-oceanic ridges are also sensitive to the fortnightly cycle, they mainly initiate at neap tides, which correspond to a minimum in the fortnightly amplitudes (Tolstoy, 2015). Actually, this configuration of quadrature, i.e., when the Moon-Earth axis is perpendicular to the Sun-Earth axis, is associated with a ...

A spring tide—popularly known as a "King Tide"—refers to the 'springing forth' of the tide during new and full moon. A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.
What is a neap tide? When the sun and moons are at right angles to each other, there is least gravitational pull, meaning the tidal range is at its lowest. The neap tide occurs 7 days after the spring tide. A neap tide is where the sun and moon are at their least aligned point. Not to scale.
19 Οκτ 2023 · Tsunamis are caused not by tides, but by underwater earthquakes and volcanoes. Tsunamis are associated with tides because their reach surpasses the tidal range of an area. So-called “ red tides ” also have nothing to do with actual tides .
20 Δεκ 2021 · The ellipsoid approaches a circle, and consequently the tide gets a smaller amplitude. This situation is called neap tide (Fig. 3.21). Figure 3.21: When the sun, the earth and the moon are in one line, the tidal forces of the sun and the moon reinforce each other and spring tides occur.
Spring tides are characterized by the highest high tides and lowest low tides, occurring during new and full moons, while neap tides, with their less extreme tidal ranges, occur during the quarter moon phases. Let's start with spring tides.
20 Δεκ 2006 · Neap tides occur when the Sun and Moon are aligned at right angles from the Earth at first- and third-quarter phases of the Moon. The result is that spring tides are higher than neap tides (Fig. 1 E). The period of time from new Moon to new Moon is called the synodic month, which has a modern period of 29.53 days.
