Which of the following is part of the continental margin?
The continental rise, continental slope, and continental shelf are the three basic components that actually make the entire structure of continental margins. The continental slopes and the continental shelves are structural constituents of continents even though they are below the surface of sea.
Which of the following is not a characteristic of active continental margins?
broad continental shelves. Characteristics of active continental margins include all of the following except: *broad continental shelves. deep-sea trenches.
What are the two types of continental margins quizlet?
The two types of continental margin are passive and active.
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 the features of the continental margins?
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.
Which of the following are not associated with a mid ocean ridge?
(a)Mid-ocean ridge is not associated with a convergent plate boundary. Explanation: Mid-ocean ridges form near divergent plate boundaries where the new ocean bottom is formed when tectonic plates separate. The Molten rock rises to the seafloor as the plates separate resulting in massive basalt volcanic eruptions.
What are the features of 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 the features of an active continental margin?
An active continental margin is a coastal region that is characterized by mountain-building activity including earthquakes, volcanic activity, and tectonic motion resulting from movement of tectonic plates. Active margins typically have a narrower and steeper continental shelf and slope.
What are the features of a continental margin quizlet?
Places where thick continental plate meets oceanic. Extremely flat extension of continents under the ocean's surface.
Which is closest to the continental margin quizlet?
1) Continental margins are boundaries between continental crust and oceanic crust. 2) Nearest the continent is the continental shelf, which is the submerged part of the continent, is almost flat.
What are the 4 parts of the 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.

Which of the following features is not associated with a typical continent continent convergent boundary?
Volcanoes aren't typically associated with continent-continent convergence zones for several reasons. Both plates are too buoyant to sink into the asthenosphere and melt, as happens at a subduction zone.
Which of the following is not found at convergent plate boundaries?
Explanation: Mid-ocean ridges form near divergent plate boundaries, where the new ocean bottom is formed when tectonic plates separate. The Molten rock rises to the seafloor as the plates separate, resulting in massive basalt volcanic eruptions.

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 …
Where is the continental rise quizlet?
The continental rise lies at the top of the continental slope.
Which is not associated with convergent plate boundaries quizlet?
Volcanoes are not associated with convergent plate boundaries. D. Rising magma from melted plates can't break through continental crust.
Which of following is not a type of plate boundary?
Explanation: The edges of two plates where it meets is called plate boundaries. The types of plate boundaries are divergent, convergent and transform.
Which is not associated with a plate boundary?
Unlike volcanoes associated with plate boundaries, hotspot, or inter-plate, volcanoes are located within tectonic plates. They are fueled by localized sources of high heat energy known as thermal plumes. These plumes of molten rock, called magma, rise from the lower asthenosphere.
What are the main features of a continental shelf?
Most continental shelves are broad, gently sloping plains covered by relatively shallow water. Water depth over the continental shelves averages about 60 meters (200 feet). Sunlight penetrates the shallow waters, and many kinds of organisms flourish—from microscopic shrimp to giant seaweed called kelp.
Which of the following is a feature of active continental margins?
Active margins are marked by earthquakes, volcanoes, and mountain belts. Unlike passive margins, they lack a continental rise and abyssal plain. Instead, the continental slope ends in an oceanic trench, and beyond the trench, the topography is hilly and irregular, often dotted with rugged volcanic seamounts.
Which of the following features of the oceans is part of the continental margin?
It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf.
What is the continental rise quizlet?
continental rise. gently sloping accumulation of sediments deposited by a turbidity current at the foot of a continental margin.
Which of the following provides the best example of an active continental margin?
An active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate. An excellent example is the west coast of South America. Active margins are commonly the sites of tectonic activity: earthquakes, volcanoes, mountain building, and the formation of new igneous rock.
Which of the following is not associated with converging plate boundaries?
Island arcs are not associated with convergent plate margins. Explanation: Deep – focus earthquakes: In seismology, a deep-focus earthquake is one that has a hypocenter depth of more than 300 kilometres.
Which of the following features is not associated with converging crustal plate boundary?
Explanation: Mid-ocean ridges form near divergent plate boundaries, where the new ocean bottom is formed when tectonic plates separate. The Molten rock rises to the seafloor as the plates separate, resulting in massive basalt volcanic eruptions.
What are the three types of plate boundaries?
- Divergent boundaries — where new crust is generated as the plates pull away from each other.
- Convergent boundaries — where crust is destroyed as one plate dives under another.
- Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What are all the types of plate boundaries?
Movement in narrow zones along plate boundaries causes most earthquakes. 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.
How many continental plates are there?
There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
Which of the following statement is not correct with regard to the continental shelf?
Continental Shelf is the gently sloping seaward extension of the continental plate. Hence, statement 3 is Not correct. The continental shelves are covered with variable thicknesses of sediments brought down by rivers, glaciers, etc.
