Where is the continental margin located?

Where is the continental margin located?

The continental margin is the underwater portion of a continent that extends from the shoreline to water depths of nearly 5,000 m. Continental margins are typically comprised of three regions: the shelf, slope, and rise.

Which features may be found within 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 is the continental shelf and where is it located?

A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope. Even though they are underwater, continental shelves are part of the continent.

What is an example of a place residing on a continental margin?

Active continental margins Examples include the Andes Mountains along the western coast of South America. Coasts along active margins are typically lifted upward by the subduction of the oceanic plate, forming terraces and cliffs that are eroded by the ocean’s waves.

What are the 3 parts of a continental margin?

The continental margins consist of three portions: (1) the continental shelf which has shallow water depths rarely deeper than 650 ft) and extends seaward from the shoreline to distances ranging from 12.3 miles to 249 miles, (2) the continental slope where the bottom drops off to depths of up to 3.1 miles, and (3) the …

What are the three types of continental margins?

What’s the difference between an active and passive continental margin?

An active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate. Passive continental margins are found along the remaining coastlines.

What are the gross features of the liver?

Gross features: Liver has 5 surfaces: anterior, posterior, superior, inferior, right lateral. Only one prominent border i.e. inferior border. Describe the anatomical and physiological/surgical lobes of liver(see the diagram above). Anatomical Lobes: The liver is divided into two lobes viz. right and left.

Where are the bare areas of the liver?

Bare areas of liver are the areas that are not covered by peritoneum. Main bare area of liver: Is located on the posterior surface. Its boundaries are: Sides: superior and inferior layers of coronary ligaments. Groove/fissure for ligamentum venosum. Porta hepatis.

Where are the segments of the liver located?

Segments I-IV are mainly located in the left physiological lobe and Segment V-VII in the right physiological lobe: Segment I (Superomedial) is the caudate lobe. Segment II (Superolateral) and Segment III (Inferolateral) are located medial to the falciform ligament . Segment IV ( Inferomedial) lies lateral to the falciform ligament.

Which is the left side of the liver?

Ligamentum venosum (obliterated ductus venosus), extends from left branch of portal vein to inferior vena cava. Enumerate the structures passing through the Porta Hepatis. Lymph vessels and nodes. Describe the visceral relations of posterior and inferior surfaces of liver.
