What are the features of ocean floor topography?
Like dry land, the ocean floor has various features including flat plains, sharp mountains, and rugged canyons (Fig. 7.1). However, the lowest point in the world ocean is much deeper than the highest point on land. The ocean floor is continually being formed and destroyed.
What are the three major topographic features on the ocean floor?
Answer and Explanation: The ocean floor or seabed can be divided into three major regions: the continental margins, abyssal plains, and mid-ocean ridges.
What is ocean floor in geography?
The ocean floor is literally the floor of the ocean. It’s the bottom of the ocean when you dive. Not too many people have gone to the floor of the ocean, as it requires special diving equipment, since the water pressure is very high the farther down you go.
What is the study of the ocean floor or its topography?
Bathymetry (/bəˈθɪmətri/; from Ancient Greek βαθύς (bathus) ‘deep’, and μέτρον (metron) ‘measure’) is the study of underwater depth of ocean floors (seabed topography), lake floors, or river floors.
Who proposed the theory of seafloor spreading?
Harry Hess: One of the Discoverers of Seafloor Spreading.
What is the structure of the ocean floor?
The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
Why is ocean floor topography important?
Accurate measurements of ocean surface topography are important for studying ocean tides, circulation and the amount of heat the ocean holds.
How is ocean floor topography different from land?
1. In Today’s days, there are separate scales for the ocean and the land topography because Ocean topography is little vaster than the land topography. 2. … For example, there will be small Islands which will be shown like a whitish mark instead of the yellowish mark as they are shown in Land Topography.
What is the most important topographic feature of the ocean floor?
The main features of the Pacific Ocean floor are the continental slopes, which drop from about 200 m to several thousand metres over a distance of a few hundred kilometres; the abyssal plains — exceedingly flat and from 4,000 m to 6,000 m deep; volcanic seamounts and islands; and trenches at subduction zones that are …
What are the major parts of the ocean floor?
The ocean floor or seabed can be divided into three major regions: the continental margins, abyssal plains, and mid-ocean ridges.
