Ocean surface topography or sea surface topography, also called ocean dynamic topography, are highs and lows on the ocean surface, similar to the hills and valleys of Earth's land surface depicted on a topographic map.

Is ocean a topography?
Ocean and land topography are defined exactly the same way. Both give the height of the ocean or land above the geoid. The geoid is the shape the sea surface would have if all the currents and tides stopped. … Tides and currents are the two major factors that contribute to the dynamic topography of the ocean's surface.
What are the different types of ocean topography types?
Underwater landforms
- Continental shelf. Starting from land, a trip across an ocean basin along the seafloor would begin with crossing the continental shelf. …
- Abyssal plains. Continuing your journey across the ocean basin, you would descend the steep continental slope to the abyssal plain. …
- Mid-ocean ridge. …
- Ocean trenches.

What is ocean bottom topography?
Ocean floor topography refers to the different forms in which the ocean floor bottom can exist. … Science has established that the topography of the ocean floor is similar to the ground topography with features such as valleys, mountains, and plateaus. Three quarters of the Earth consists of ocean water.
What is the major topographic feature of the Atlantic Ocean called?
the Mid-Atlantic Ridge The bottom topography of the Atlantic Ocean is characterized by a great submarine mountain range called the Mid-Atlantic Ridge. It extends from Iceland in the north to approximately 58 degrees south latitude, reaching a maximum width of about 1,000 miles (1600 km).
What is a submarine valley?
Submarine canyons – Submarine canyons are defined as “steep-walled, sinuous valleys with V-shaped cross sections, axes sloping outward as continuously as river-cut land canyons and relief comparable to even the largest of land canyons” (Shepard, 1963).
What are the three major topographic provinces of the ocean floor?
Physiography and bathymetry (submarine landscape) allow the sea floor to be subdivided into three distinct provinces: (1) continental margins, (2) deep ocean basins and (3) mid-oceanic ridges.
What are the three major topographic units of the ocean floor?
Physiography and bathymetry (submarine landscape) allow the sea floor to be subdivided into three distinct provinces: (1) continental margins, (2) deep ocean basins and (3) mid-oceanic ridges.
What are mid-ocean ridges?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
