Back

Spring tides occur when the Earth, Moon, and Sun are aligned, resulting in higher high tides and lower low tides. They happen during the new moon and full moon phases.

What is the role of the Sun in tidal movements?

Back

The Sun's gravitational pull also affects tides, but its effect is less than that of the Moon. It contributes to the variation in tidal heights.

Front

What is a tidal range?

Back

The tidal range is the difference in height between high tide and low tide.

Front

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides.
