What are the effects of the relative positions of the Sun, Moon, and Earth on ocean tides?

Back

The relative positions of the Sun, Moon, and Earth create gravitational forces that affect ocean tides. When the Sun, Moon, and Earth are aligned (during full moons and new moons), tides are higher (spring tides). When they are at right angles (during the first and third quarters), tides are lower (neap tides).

What is the difference between spring tides and neap tides?

Back

Spring tides occur when the Sun, Moon, and Earth are aligned, resulting in higher tides. Neap tides occur when they are at right angles, resulting in lower tides.
