Smaller, gentle rises:
* Hill: A rounded elevation of land, smaller than a mountain, typically with a gradual slope.
* Knoll: A small, rounded hill, often with a grassy top.
* Mound: A pile of earth or rock, often artificial.
More pronounced rises:
* Ridge: A long, narrow elevation of land, often formed by the meeting of two slopes.
* Escarpment: A steep cliff or slope, often formed by erosion.
Other possibilities:
* Plateau: A flat, elevated area of land.
* Butte: An isolated, steep-sided hill, often with a flat top.
* Mesa: A flat-topped hill with steep sides, larger than a butte.
The best answer depends on the specific context and what you're trying to describe.
