-involves the convergence of an oceanic plate and a plate whose leading edge contains continental crust-subduction and partial melting of rock generates primary magmas Magma is less dense than surrounding rock so it begins ti rise - as it rises it melts the continental crust and the mixing of magma produces andesitic compositions. Active continental margins are those that are tectonically active such as along much of the Pacific coast.

Which of the following statements regarding active and passive continental margins is true.
. Which of the following statements accurately describes active continental margins. Kendal reports the following income and loss. Instead the continental slope ends in an oceanic trench and beyond the trench the.
Turbidity currents and river erosion carve deep submarine canyons. They generally have a deep trench. Between continental and oceanic crustIn an active continental margin the boundary between the continent and the ocean is also a tectonic plate boundary so there is a lot of geological activity around the margin.
B crust is destroyed at their boundary C guyots form at their edge D they generally have a continental rise Answer. Which of the following statements regarding active and passive continental margins is true. Which statement accurately describes active continental margins.
Active margins are commonly the sites of tectonic activity. They are characteristic of the margins of the Atlantic Basin. An active margin receives large amounts of sediment whereas a passive margin is sediment starved.
Which of the following is a characteristic of an active continental margin. Salary 120000 Income from activity A 36000 Loss from activity B 30000. Passive continental margins line coasts that are far from tectonically active areas.
The west coast of the United States is an example of an active margin. Active continental margins tend to have a narrow continental shelf which is the submerged border of the continent. Water expands as it freezes causing the crack walls to be pushed apart.
They are found only on active continental margins. The characteristics of the active continental margins include the following. So the continent drops off quickly along an active margin and meets up with the.
Which of the following is true of active continental margins A they do not have a continental break. This problem has been solved. Active margins are marked by earthquakes volcanoes and mountain belts.
Active continental margins are characterized by rugged coastlines with narrow beaches and steep sea cliffs. On the other hand passive continental margins are witnessed along the left coastlines. D they generally have a continental rise Related posts.
Continental margins are defined as active or passive according to the presence or absence respectively of plate tectonic activity. The active margins are generally the locations of tectonic activity. They are areas of frequent earthquakes and volcanoes where lithospheric plates are converging.
Active continental margins are not associated with deep-ocean trenches whereas passive margins are associated with deep-ocean. An active continental margin is witnessed on the prominent edge of the continent where it is colliding into an oceanic plate that is the process of subduction taking place. They are found majorly on the.
The Continental Congress proclaimed the hero. Unlike passive margins they lack a continental rise and abyssal plain. They leave deposits of graded beds called guyots.
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. Q1What is the difference between an active continental margin and a passive continental margin. An active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate.
This includes the earthquakes volcanic activity and tectonic motion thus resulting from the movement of the tectonic plates. They are areas of frequent earthquakes and volcanoes where lithospheric plates are converging or are. The West Coast of the United States is an active continental margin Figure 15-8.
What is true of active continental margins. Continental margins refer to the region of transition from the land to the deep seafloor ie. It is one of the three major zones of the ocean floor the other two being deep-ocean basins and mid-ocean ridgesThe continental shelf is the relatively shallow water area found in proximity to continents.
Active continental margins are not associated with active volcanoes whereas passive margins are associated with active volcanoes. An active continental margin is like a coastal region that is marked by mountain-building activity. They are areas where lithospheric plates are actively moving apart.
Earthquakes volcanoes mountain building and the formation of new igneous rock. Earthquakes volcanoes mountain building and the formation of new igneous rock. A passive margin is passively carried along by plate tectonics in a transform system like the San Andreas whereas an active margin is a trench.
Which of the following statement is true. Active margins are commonly the sites of tectonic activity. They are responsible for creating the continental shelf.
An excellent example is the west coast of South America. An excellent example is the west coast of South America. An active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate.
Which of the following statements about turbidity currents is true. Earthquakes and volcanoes are associated with active continental margins which are marked by a landward continental shelf a much steeper continental slope that ends at an active ocean trench and an irregular. The continental margin consists of three different features.
This produces some common features at active continental margins. Active continental margins occur at plate boundaries. They are regions of great geological stability.
