Coastal Landscapes and Beach Formation

The video tutorial covers coastal landscapes of deposition, focusing on the formation of beaches, storm beaches, tombolos, sand spits, lagoons, and sand dunes. It explains how constructive waves contribute to beach formation, the role of swash and backwash, and provides examples of each feature in Ireland. The tutorial also includes tasks for students to define, explain, and diagram these coastal features.

What is the primary difference between coastal landscapes of deposition and erosion?

• Deposition involves the accumulation of material, while erosion involves removal.
