Continental shelves

Continental shelves

Most continents, including Australia, have a relatively narrow rim of submerged continental crust. However, the New Zealand continent is unique: 93% of it is submerged, with huge areas of relatively shallow seas extending north-west as far as tropical New Caledonia, and south-east to the scattered subantarctic islands. Most of the continental area is made of true continental crust, but to the north-east (upper right) it is high-standing oceanic crust that has been raised by tectonic forces.
