What: Single ravines or whole systems of connected ravines, which cut into the terrain

How: At the land uplift beaches, waves wash away all the fine material from the moraine. This fine material settles to the bottom of sheltered bays. Then land uplift raises the seabed above the sea. The fine sediment soil is easily eroded, so running water can cut long ravines into the terrain. In other words, ravines are visible on the terrain as v-shaped grooves, which have often a stream running at the bottom. Landslides are also common in the sediment soils.

Where to see: Near the northern entrance of the Skuleskogen National Park

Fun fact: Ravines are important for biodiversity because their microclimate differs from the surroundings and offers habitats for different species.
