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 a active continental margin have that a passive margin does not?
Subduction. A subduction trench.
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?
The subduction of oceanic lithosphere under a continent forms a volcanic arc on the continental margin. This arc is characterized by intense volcanic activity producing a chain of stratovolcanoes and igneous plutons intruding into the continental crust.
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.
A passive continental margin has a while an active margin does not.?
An active continental margin may have a trench.
Is An oceanic plate and continental plate colliding?
When an oceanic plate collides with a continental plate, the denser oceanic plate typically subducts beneath the lighter continental plate due to the difference in density. This subduction can lead to the formation of volcanic mountain ranges along the continental margin. The oceanic plate may also undergo partial melting, leading to the formation of magma that can erupt to the surface.
What is continental margin?
The continental margin is the zone of the ocean floor that separates the thin oceanic crust from thick continental crust.
Which portion of the continental margin serves as a boundary between the oceanic crust and the continental crust?
The portion of the continental margin that serves as a boundary between the oceanic crust and the continental crust is called the continental shelf. This is the shallowest part of the margin, located between the shoreline and the continental slope.
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.
When a terrane impacts the margin of a continental plate what is the fate of the oceanic plate upon which the terrane has been traveling?
When a terrane impacts the margin of a continental plate, the oceanic plate beneath it is typically subducted, or pushed downward, into the mantle due to the collision's tectonic forces. This process can lead to the formation of mountain ranges and volcanic activity at the continental margin. Additionally, the subduction can result in the destruction of the oceanic crust as it melts and recycles into the mantle. Ultimately, the fate of the oceanic plate depends on the dynamics of the collision and the specific geological conditions at play.
The margin of a continent is the boundary between continental crust and?
oceanic crust
