continental shelf

This term is a technical geological and oceanographic designation. It describes the specific transition zone between land and the deep ocean, characterized by a relatively flat, shallow gradient.

In legal and political contexts, the term is frequently used to define a nation's Exclusive Economic Zone (EEZ), determining where a country has the sovereign right to exploit minerals, oil, and gas.

Because it refers to a specific geological feature of a continent, it is typically treated as a countable noun when discussing different continents or different sections of a shelf, though it often appears in the singular when referring to the general concept.
