How does the moon's position affect tides?

Back

The moon's position relative to the Earth affects the strength of its gravitational pull, which in turn influences the height of the tides.

What is the role of the sun in tidal movements?

Back

The sun also exerts a gravitational force on the Earth's oceans, contributing to the tidal movements, although its effect is less than that of the moon.

What is the significance of the tidal cycle?

Back

The tidal cycle is significant for navigation, fishing, and coastal ecosystems, as it affects water levels and the availability of marine resources.
