Knoll (oceanography)

In marine geology, a knoll is defined as a rounded underwater hill, not exceeding 1000 meters in height.[1] Any rounded underwater features exceeding that height are referred to as seamounts.[2] They are believed to cover around 16.3% of the world's seafloor.[3]

## Examples

* Orphan Knoll
* Graveyard Seamounts
