The video explains the classification of tides, starting with an introduction to tides and their causes, such as the gravitational and centrifugal forces of the moon and sun. It describes a tidal day as the time it takes for a specific site on Earth to rotate from a point under the moon to the same point again, lasting 24 hours and 50 minutes. The video then classifies tides into diurnal, semi-diurnal, and mixed semi-diurnal types, detailing their characteristics and regions where they occur. It concludes with a comparison of these tide types and encourages viewer engagement.
