The sides of Table Mountain in South Africa appear very much like a cliff, as do the sides of mesas.

Escarpment cliffs usually occur along geological faults.

Some of the largest cliffs on Earth are found underwater. For example, an 8,000 m drop over a 4,250 m span can be found at a ridge sitting inside the Kermadec Trench.

The highest cliff in the solar system may be Verona Rupes, an approximately 20 km (12 mi) high fault scarp on Miranda, a moon of Uranus.

There is no ocean on the moon Miranda.
