1. Cliffs: Coastal cliffs are steep, rocky faces that separate the land from the ocean. They are formed when waves erode the edge of the land, causing it to collapse and create a vertical drop. Cliffs can be several hundred feet high and can provide stunning views of the ocean.

2. Beaches: Beaches are sandy or pebbly areas of land that lie along the edge of the ocean. They are formed when waves deposit sediment on the shore, which gradually builds up over time. Beaches can be wide and expansive or narrow and secluded, and they can be popular tourist destinations for swimming, sunbathing, and walking.

3. Fjords: Fjords are narrow, deep inlets of the sea that are surrounded by steep cliffs. They are formed when glaciers carve deep valleys into the land and then retreat, leaving behind a long, narrow waterway. Fjords can be several hundred miles long and can offer stunning scenery with their towering cliffs and deep blue waters.
