/kɑntəˈnɛntəl ʃɛlf/ – Phrase
Definition: thềm lục địa.
A more thorough explanation: The legal definition of the term “continental shelf” refers to the submerged extension of a continent’s landmass, consisting of the seabed and subsoil of the submarine areas that extend beyond a country’s territorial sea to the outer edge of the continental margin, or to a distance of 200 nautical miles from the baselines from which the breadth of the territorial sea is measured where the outer edge of the continental margin does not extend up to that distance.
Example: The country claimed exclusive rights to the resources found on its continental shelf.
