How do ocean tides change with the Moon’s position?

Quick Answer

The Moon’s gravity creates tidal bulges, and the Sun modifies them to produce stronger spring tides or weaker neap tides.

The Full Story

Tides are driven mainly by the Moon’s gravity, which pulls ocean water into a bulge on the side of Earth facing the Moon and another on the opposite side. As Earth rotates, coastlines move through these bulges and experience high and low tides. When the Sun and Moon line up during new moon or full moon, tides are stronger and are called spring tides. When the Sun and Moon are at right angles, the result is weaker neap tides.

Key Facts

1.The Moon is the main driver of tides
2.Spring tides occur when Sun, Earth, and Moon line up
3.Neap tides happen when solar and lunar effects partly cancel
