1. CONTINENTAL SHELF.
тЧЗ Continental shelf is gently sloping (gradient of 1┬░C or less) seaward extension of Continental plate.
тЧЗ Shelves cover 7.5% of total area of the Oceans.
тЧЗ Shelf typically ends at very steep slope, called the Shelf break.
2. CONTINENTAL SLOPE.
тЧЗ Gradient of slope region varies between 2-5┬░C.
тЧЗ Continental slope boundary indicates the end of Continents.
тЧЗ Canyons and trenches are observed in this region.
3. CONTINENTAL RISE.
тЧЗ Continental slope gradually loses its steepness with depth.
тЧЗ When slope reaches a level of between 0.5┬░ and 1┬░, it is referred to as the Continental rise.
4. DEEP SEA PLAIN or ABYSSAL PLAIN.
тЧЗ Deep sea plain are gently sloping areas of the ocean basins.
тЧЗ They are flattest and smoothest regions of the world.
тЧЗ These plains are covered with fine - grained sediments like Clay and silt.
