See in Glossary features. In the Terrain Inspector, click the Paint Terrain icon, and select Smooth Height from the list of Terrain tools.

The Smooth Height tool does not significantly raise or lower the Terrain height; instead, it averages out nearby areas. This softens the landscape and reduces the appearance of abrupt changes.
