Where are broad sediment covered continental shelves found in active pr passive margins?
Broad sediment-covered continental shelves are typically found in passive margins where there is a lack of tectonic activity and the crust is stable. Active margins, on the other hand, are associated with tectonic activity like subduction zones or rift zones, which can result in narrower shelves due to more abrupt changes in the seafloor elevation.
What is one structure that you would find at an active continental margin that you would not at a passive?
One structure you would find at an active continental margin that you would not find at a passive margin is a subduction zone. Subduction zones occur at active margins where tectonic plates collide, resulting in one plate being forced beneath the other. This process can lead to the formation of volcanic arcs, deep ocean trenches, and earthquakes.
Is fracture zone part of continental margin?
Yes, fracture zones can be found on the ocean floor near continental margins. They are areas of intense tectonic activity where tectonic plates slide past each other, creating fractures in the Earth's crust. These zones are often associated with transform plate boundaries.
What boundary is it called when an oceanic plate descends beneath a continental plate?
It's called destructive plate margin/boundary, or convergent plate margin though this term applies to all plate margins where two plates are moving towards each other (such as continental + continental or oceanic + oceanic).
What are plates moving toward each other?
Plates that move toasted each other are detractive plates meeting at a destructive margin. If a continental and an oceanic plate move towards each other, earthquakes and volcanoes occur, this is called a subduction margin, but if the plates are both continental then fold mountains form this is a collision margin
What are the characteristic of margin?
The most important is supply and demand, the margin just represents how much you can squeeze from the sale and can I buy more which I can sell for the same amount. It's one of a few metrics to use other important things to consider is whether your costs are squeezing margins and where to look to squeeze higher margins.
What are margins?
A margin is a space separating text or other elements from the edge of the paper commonly adjusted through the page setup. Most programs allow for the Top, Bottom, Left, and Right margins to be set. The standard margin settings are 1" Top and Bottom and 1.25" Left and Right.
How are convergent plate margins characterized?
Convergent plate margins are characterized as collision zones between plates and may involve continental to continental crust, continental to oceanic crust, or oceanic to oceanic crust. Those that involve oceanic crust result in subduction of the more dense plate into the Earth's mantle. Continental to continental plate collisions result in uplift of the surface features and mountain building and the margin may eventually become welded together.
What are Continental margins near the edges of converging plates?
Continental margins near converging plates are often characterized by subduction zones where one plate is forced beneath the other. This leads to the formation of deep ocean trenches and volcanic arcs. Earthquakes and mountain building can also occur along these margins as a result of the intense tectonic activity.
What is a slim profit margin?
Profit margins are usually deducted from all costs, depreciation, interest, taxes, and other expenses. The formula is: (Total Sales - Total Expenses) / Total Sales = Profit Margin Note that preferred stock dividends are usually calculated, but not ordinary stock dividends.
What is the definition of plate margin?
A plate margin is the boundary where two tectonic plates meet. These margins can be divergent (moving apart), convergent (moving together), or transform (moving past each other).Plate margins are dynamic areas where geological activities like earthquakes and volcanic eruptions often occur.
What happens at a destructive margin?
At a destructive margin, also known as a convergent boundary, two tectonic plates collide. One plate is usually forced beneath the other in a process called subduction. This can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
