  1. Ocean Topography

  2. What’s it look like under the waves?

  3. Ocean topography • Continental shelf: the underwater edge of a continent • Continental slope: the descent from the continental shelf to the ocean bottom • Volcanic island arc: a usually arc-shaped chain of volcanoes located on the margin of the overriding plate at a convergent plate boundary • Abyss: an immeasurably deep chasm, depth, or void

  4. Ocean topography • Mid ocean ridge: continuous, submarine mountain chain extending approximately 50,000 mi (80,000 km) through all the world's oceans, separating them into distinct basins • Abyssal plain: the flat lands beyond the continental shelf that cover almost half the ocean floor • Guyot: A flat-topped, extinct submarine volcano having an elevation of over 1,000 m (3,280 ft) above the ocean floor

  5. Ocean topography • Ocean trench: Submarine valley. Ocean trenches are characterized by the presence of a volcanic arc on the concave side of the trench • Seamount: are literally undersea mountains rising from the bottom of the sea that do not break the water's surface
