A zone plate is a device which uses diffraction through alternate transparent and opaque rings to function as a lens.
The subducted plate descends into the mantle at subduction zone
The subducted plate descends into the mantle at subduction zone
A subduction zone is where one plate is being subducted ( pulled down) under another plate, No it is not a plate boundary but it is were it happens. hope this helps
The density of the tectonic plates involved determines whether a subduction zone or collision zone is formed at a destructive plate margin. If one plate is denser than the other, it will subduct beneath the other plate, forming a subduction zone. If the plates have similar densities, they will collide and form a collision zone.
A subductilon zone
subduction zone
The subduction zone formed when an oceanic plate and a continental plate converge is called an oceanic-continental subduction zone. In this setting, the denser oceanic plate is forced beneath the less dense continental plate, leading to the formation of volcanic arcs and deep oceanic trenches.
It is a subduction zone.
Convergent plate boundaries where an oceanic plate collides with a continental plate or another oceanic plate are most likely to result in a subduction zone. In this scenario, the denser oceanic plate is forced beneath the less dense continental plate, creating a subduction zone.
This type of zone is called a subduction zone. At subduction zones, the oceanic plate is forced beneath the continental plate due to its denser composition. This process can lead to the formation of volcanic arcs and deep ocean trenches.
The plate boundary for Unzen volcano is the subduction zone where the Philippine Sea Plate is being subducted beneath the Eurasian Plate. This subduction zone is part of the larger convergent boundary between the Philippine Sea Plate and the Eurasian Plate.
The focal length of a zone plate is typically determined by the number of zones it contains. It is usually equal to the radius of the outermost zone multiplied by the square of the number of zones.
