Sagot :
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
Answer:
Appalachian: A. Two continents colliding.
North American Cordillera: B. Terrane accretion
Aleutian plate: D. Oceanic convergence
Andes Mountain range: C. An oceanic plate and continental plate colliding.
Explanation:
Appalachian Mountains formed as a result of collision of two continental plate’s i.e North Africa & America. These two plates crashed into each other and then separated later on.
In the accretion process, land mass start depositing over each other for a certain period of time to forma a large mountain. The North America Cordillera formed through this subsequent deposition after the initial collision between the Pacific and the North American plates
Aleutian plate were formed when one plate (oceanic) slide below the other plate (continental)
Andes were also formed by the collision between an oceanic plate and a continental plate where the oceanic plate sub ducts below the continental plate.
