What are main features of continental margins?
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°. …

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 3 characteristics of the continental shelf?
Continental shelves are usually covered with a layer of sand, silts, and silty muds. Their surfaces exhibit some relief, featuring small hills and ridges that alternate with shallow depressions and valleylike troughs.
What is a continental margin?
The CONTINENTAL MARGIN is the transition to the deep ocean basin. The margin belongs mostly to the continent. The CONTINENTAL SLOPE, as its name implies, is the sloping edge of the continent as it merges into the deep ocean basin. The steepness of the continent slope differs from place to place.
What is not part of the continental margin?
Which of the following is NOT part of the continental margin? coral reefs surrounding a lagoon. You just studied 65 terms!
What is the continental margin quizlet?
Continental margin. the zone of the ocean floor that separates the thin oceanic crust from thick continental crust. Together, the continental shelf, continental slope, and continental rise are called the continental margin.
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 cuts through the continental margins?
The Bering Canyon north of the Aleutian Islands in the North Pacific Ocean is an example. It cuts through the continental margin for more than 255 miles (410 kilometers) and is the longest canyon in the world.
What is the continental shelf quizlet?
Continental shelf. a gently sloping, shallow area of the ocean floor that extends outward from the edge of a continent.
Which one of the following is part of the passive continental margin?
The Atlantic and Gulf coasts show the classic form of a passive continental margin: a low-lying coastal plain, broad continental shelf, then a steep continental slope, gentle continental rise, and flat abyssal plain. This topography is a consequence of the transition from thick continental to thin oceanic crust.
Which area is the boundary between continental and oceanic crust quizlet?
1) Continental margins are boundaries between continental crust and oceanic crust.
Which is not part of the continental margin?
Which of the following is NOT part of the continental margin? coral reefs surrounding a lagoon.
What are the three major regions of the ocean floor quizlet?
What are the three main regions of the ocean floor? The ocean floor regions are the continental margins, the ocean basin floor, and the mid-ocean ridge.
What are three major regions of the ocean floor?
> ceanographers studying the topography of the ocean floor have vided it into three major regions. The ocean floor regions are le continental margins, the ocean basin floor, and the mid-ocean dge.
What are the active continental margins quizlet?
Active Continental Margins- where the oceanic lithosphere is being sub ducted beneath the continent. Often associated with deep ocean trenches. Located primarily around the Pacific Ocean. Sediments and rocks can be scraped from the descending plate and accumulate on the continental plate as an accretionary wedge.
Which is not a part of the continental margin?
Which of the following is NOT part of the continental margin? coral reefs surrounding a lagoon.
Which 3 geological features can be created by a divergent boundary?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
What three things are created by convergent boundaries of oceanic and oceanic crust?
Oceanic/Oceanic Convergent Boundaries Such a convergent boundary includes a seafloor trench marking the earthquake-rattled subduction zone as well as an island arc: a line of volcanoes created by rock-melt in the mantle associated with subduction.
Which of the following structures comprise a 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 relatively shallow water area found in proximity to continents. Continental margins constitute about 28% of the oceanic area.
What are 3 regions of the ocean floor?
> ceanographers studying the topography of the ocean floor have vided it into three major regions. The ocean floor regions are le continental margins, the ocean basin floor, and the mid-ocean dge.
What are the 3 major regions of 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. These regions are…
What are the three major regions?
There are three types of regions: formal, functional, and vernacular.
What are the continental margins of the Pacific Ocean?
Two major types of the continental margins include (1) active continental margin and (2) passive continental margins. The “Pacific Ocean” is characterized by the active continental margins which are mainly the narrow tectonically active areas associated with the volcanoes, oceanic trenches, and earthquakes.
What are the two types of continental margins?
There are two types of continental margins: active and passive margins. Active margins are typically associated with lithospheric plate boundaries. These active margins can be convergent or transform margins, and are also places of high tectonic activity, including volcanoes and earthquakes.
What are the 3 types of plate boundaries?
For example, sections of Earth's crust can come together and collide (a “convergent” plate boundary), spread apart (a “divergent” plate boundary), or slide past one another (a “transform” plate boundary). Each of these types of plate boundaries is associated with different geological features.
What are the three types of convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
What are the 3 plate boundaries?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
What are the 3 convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
