Beach Profiles and Coastal Features

The video tutorial explains depositional landforms, focusing on beaches, sand dunes, spits, and bars. It describes how beaches form in sheltered areas due to sediment deposition, with sandy beaches in low-energy environments and shingle beaches in high-energy areas. The formation of sand dunes is detailed, highlighting the role of pioneer plants and vegetation succession. The video also covers the creation of spits and bars through longshore drift, leading to the formation of lagoons.

What type of environment is most likely to form sandy beaches?

• Rocky environments

What is the main reason shingle beaches are formed?
