* Canyons: Formed by rivers eroding the land over time, canyons have steep, almost vertical sides.
* Cliffs: These are steep, rocky faces that often form along coastlines or at the edge of plateaus.
* Mountains: Though not always perfectly steep, mountains often have very steep slopes, especially near their peaks.
* Volcanoes: Volcanoes can have steep sides, especially those that are conical and formed by explosive eruptions.
* Escarpments: These are long, steep cliffs that can be formed by faulting or erosion.
