Which mountain range forms near a subduction zone?
The Andes mountain range in South America is an example of a mountain range that forms near a subduction zone. The subduction of the Nazca Plate beneath the South American Plate has contributed to the uplift and formation of the Andes.
When oceanic and continental crust collide at a subduction zone one plate is forced under the other The angle at which the subducting plate descends is due to what factors?
The angle at which the subducting plate descends at a subduction zone is primarily determined by the age and density of the plates involved. Older, colder, and denser oceanic plates are more likely to subduct at steeper angles compared to younger, warmer plates. However, other factors such as sediment accumulation and plate geometry can also influence the subduction angle.
How was the cascade range formed?
The Cascade Range was formed by the subduction of the Juan de Fuca plate beneath the North American plate. This process created volcanic activity along the subduction zone, leading to the formation of the Cascade volcanoes. The range extends from northern California to British Columbia, with peaks such as Mount Rainier and Mount Hood.
What can be indications that a given mountain range was not formed by subduction?
Indications that a mountain range was not formed by subduction include the absence of deep oceanic trenches, lack of volcanic activity, and the presence of diverse rock types that are not associated with subduction zones. Additionally, the orientation of the mountain range may not align with the typical pattern of subduction-related mountain building.
What 2 continents whose edges are not all plate boundaries?
North America and South America have edges that are not all plate boundaries. The boundary between North and South America is known as the Central American Subduction Zone, where the Cocos Plate is subducting beneath the Caribbean Plate.
Is Mt Krakatoa a hot spot?
Krakatoa is not associated with a hot spot. It is associated with a subduction zone.
Is krakatoa a hot spot volcano?
Some websites say it was on a subduction zone, but Discovery Channel says it was a hot spot, so you can decide for yourself.
Is Krakatoa a divergent convergent or transform boundary?
Krakatoa is located at a convergent boundary, where the Indo-Australian Plate is being subducted beneath the Eurasian Plate. This subduction zone can lead to intense volcanic activity due to the melting and rising of magma from the subducted plate.
Is Krakatoa a constructive or destructive plate margin?
Krakatoa is located on a destructive plate margin where the Indo-Australian plate subducts beneath the Eurasian plate. This subduction zone has led to the formation of volcanic islands in the region, including Krakatoa.
What is the rock or mineral formation of magma of Krakatoa?
Acid (highly siliceous) - much of it andesite if I recall my reading of it correctly. Krakatoa (or '~tau') is a still-active island-arc volcano above a complex, very active subduction zone.
Is mount Cleveland a subduction zone?
Moun Cleveland formed as a result of a subduction zone, but is not a subduction zone in and of itself. A subduction zone is a feature that forms volcanoes, not a kind of volcano.
The area where a plate descends is a?
subduction zone
What kind of explosions do composite volcanoes?
Composite volcanoes have subduction zone eruptions. Some of the most spectacular of volcanoes such as Krakatoa and Mt. St. Helen's have had this type of explosion.
What type of plate margine is Krakatoa found on?
Krakatoa is located on a convergent plate margin, specifically where the Indo-Australian Plate is subducting beneath the Eurasian Plate. This subduction zone is known for producing volcanic activity due to the collision between the two plates.
Which convergent boundaries do not have a subduction zone?
A continent to continent convergent boundary does not have a subduction zone.
What Fault Is Krakatoa on?
Krakatoa is located on the boundary of two tectonic plates: the Eurasian Plate and the Indo-Australian Plate. This area is known as the Sunda Arc subduction zone, where the Indo-Australian Plate is subducting beneath the Eurasian Plate, leading to volcanic activity in the region.
What term is used to describe the location where sinking of a plate occurs?
subduction zone
