Answer 2

Shelf-Break

Explanation:

• "Shelf break" is a  "sub-merged offshore edge" of a "shallow continental shelf", wherein the "sea-floor" shifts to "continental slope". A "shelf-break" is characterised by "markedly raised" "slope gradients" towards the "deep ocean bottom". The "shelf-break" can be  as "shallow" as "20metres" "(65feet)" & as "deep" as "550metres"; the world-wide avg depth is "133metres".
• The "seven" major world divisions are referred to as "continents". From the edge of a "continent, the continental shelf" "stretches to a drop point", known as the "shelf break". With the "separation", in what is considered the "continental slope", the "shelf" "descends" to the "deep ocean floors".
