What is the difference between the continental slope and the continental rise?
The continental shelf starts from the shore to a few miles out with less gradient of slope. The continental slope starts after shelf-break with a higher slope gradient, then follows the continental rise and abyssal-plain.
List the subdivisions of the continenal margin?
The three parts of the continental margins are the Continental shelf, the Continental slope, and the Continental rise.
When is new ocean crust or sea floor produced?
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
What is a margin of safety as well as how it can help minimize risk. Use examples in your explanation.?
Margin of safety is the difference between the intrinsic value of a stock and its market price. To have a margin of safety, one must manage one's financial needs thriftily.
Is a honey locust leaf margin entire toothed or lobed?
toothhed
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 does a continental margin have that an active margin does not?
Subduction. A subduction trench.
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
What does a active continental margin have that a passive margin does not?
Subduction. A subduction trench.
A passive continental margin has a while an active margin does not.?
An active continental margin may have a trench.
What is a subduction zon as it relates to earth science?
A subduction zone is a place at the margin of a continent where the neighbouring oceanic plate is 'subducted'. That is, the oceanic plate, moving toward the continental plate, goes down into the mantle because it is heavier than the continental plate. Subduction zones typically cause deep ocean trenches.
Where oceanic crust collides with continental crust is the?
This type of plate boundary is a convergent boundary where subduction of the denser oceanic slab into the mantle will occur. Because of this it may also be called a destructive margin.
What does the continental margin consist of?
The continental margin is the zone of ocean floor that separates oceanic crust and continental crust. It accounts for 28% of all oceanic area.
Subduction of oceanic lithosphere under a continental block gives rise to what type of geologic structure that is characterized by a continental volcanic arc and associated igneous plutons?
andean-type plate margin
What is a continental margin?
A continental margin is the zone of transition between a continent and the deep ocean floor. It includes the continental shelf, continental slope, and continental rise. It is an area where sediments from the continent are deposited and tectonic activity can occur.
What is continental margin?
The continental margin is the zone of the ocean floor that separates the thin oceanic crust from thick continental crust.
What is the boundary between the oceanic crust and the continental crust known as?
Continental margin
