La Luna y las mareas vivas

The video explains how the moon's gravitational pull creates tides on Earth, with high and low tides occurring every 12 hours. Spring tides, which are more extreme, occur during the new and full moons when the moon and sun's gravitational forces align. These tides can have dramatic effects on rivers, such as the Severn and Amazon, causing large waves. The Black Dragon Tide in China is a notable tidal event, influenced by seasonal winds and the moon's gravity.
