Landforms part 3: Coastal Landforms

The video explores various coastal landforms, focusing on beaches, dunes, sea cliffs, and sea stacks. It explains how beaches are formed by sediment deposits and highlights the diversity of beach sediments in different locations. The importance of dunes in stabilizing beaches is discussed, along with their formation by wind. The video also covers the creation of sea cliffs and sea stacks through wave erosion, with examples from New Brunswick, Canada.

• In mountainous regions

• In urban areas

• In the ocean

• Far inland, like in Death Valley

What are sea stacks, and how are they formed?

• Columns of rock left after sea cliffs erode
