What are the types of continental margins?
Continental Margins
| Continental margin | Plate Boundary Nearby | Continental shelf width |
|---|---|---|
| Active/Pacific type | Conservative or destructive near margin | Generally narrow |
| Passive/Atlantic type | None. Constructive boundary has rifted away, and over time will be far away (“mid-ocean”) | Generally wide |
What are the main features of a continental margin?
Major Continental Margin Features
- Continental shelf. This is very shallow water, and underlain by continental crust.
- Continental slope. This is much steeper than the shelf, usually about 3° but ranging from 1-10°.
- Continental rise.
- Abyssal plains.
What are three major features of a passive continental margin?
The features comprising passive continental margins include the continental shelf (the flooded extension of the continent), the continental slope (has the steepest slope), and the continental rise.
What are the 4 parts of the continental margin?
The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area.
What are the three major regions of the ocean floor?
three distinct provinces:
- continental margins.
- deep ocean basins.
- mid-ocean ridges.
What are three major features of a passive continental margin quizlet?
A passive continental margin is tectonically inactive and features a continental shelf, a continental slope, and a continental rise (from land toward the sea); An active continental margin is located along a convergent plate boundary, has a deep-ocean trench where subduction takes place, and may have evidence of an …
What is continental margin in geography?
continental margin, the submarine edge of the continental crust distinguished by relatively light and isostatically high-floating material in comparison with the adjacent oceanic crust. It is the name for the collective area that encompasses the continental shelf, continental slope, and continental rise.
What are the three main regions of continental margins quizlet?
The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area. underwater mountain range, formed by plate tectonics.
What are the three features of the continental margin?
The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. The continental shelf is the portion of the continental margin that transitions from the shore out towards to ocean. They are believed to make up 7 percent of the sea floor.
What is the steepest part of the continental margin?
The continental slope is said to be the steepest part of the continental margin, where there is a sudden decrease in slope or it suddenly descends down to the ocean floor and the sea floor begins to level out towards the abyssal plain.
What are the subdivisions of the continental margin?
For purposes of study, the continental margin is usually subdivided into three major sections: the continental shelf, the continental slope, and the continental rise. In addition to these sections, one of the most important features of the continental margin is…
What is the true margin of a continent?
The continental margin is the shallow water area found in proximity to continent. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area. [1] Sep 16 2019
