A neap tide is when the sun and moon are at right angles, creating the least tidal range. A spring tide is when they are aligned, creating the greatest tidal range. Learn how the sun, moon and Earth's rotation affect the tides.
28 Σεπ 2024 · neap tide, tide of minimal range occurring near the time when the Moon and the Sun are in quadrature. This condition is geometrically defined as the time at which the line from the Earth to the Moon is at right angles to the line from the Earth to the Sun.
Neap tides are moderate tides that occur when the Sun and Moon are at right angles to each other. They happen around the first and last quarter phases of the Moon, and result in moderate highs and lows. Learn more about how the Moon and Sun affect Earth's tides.
Neap tides are periods of moderate tides that occur twice a month when the sun and moon are at right angles to each other. They have lower tidal ranges than spring tides and affect tidal currents for navigation and safety.
Learn how the alignment of the sun, moon, and Earth affects the tidal range and impact on coastal areas. Spring tides have the highest highs and lowest lows, while neap tides have the smallest differences.
Neap Tides The tidal range is smallest around the Quarter Moons /Half Moons because the gravitational force from the Moon and the Sun counteract each other at these 2 points of the lunar month . These tides are called neap tides or neaps, from Anglo-Saxon, meaning without the power .
