Tides and Waves Concepts

The video tutorial covers the concept of tides, including the intertidal range, effects of tides on fishing, waste management, and shipping. It explains the mechanics of tides, their daily changes, and how they are influenced by the Earth's rotation and the Moon's position. The tutorial also discusses wave generation, the role of wind, and the impact of natural events like earthquakes, leading to tsunamis.
