The Moon and Spring Tides

The video explains how the moon's gravitational pull causes tides on Earth, with high and low tides occurring approximately every 12 hours. It describes spring tides, which are more extreme and occur during new or full moons when the moon's gravity combines with the Sun's. The video highlights specific tidal phenomena, such as the Severn Estuary's tidal bore and the Amazon River's larger-scale tidal bore. It also covers the Chiantang River's Black Dragon tidal bore in China, a dangerous event that attracts daredevils.

Describe the phenomenon known as the 'seven bore'.
