Accretionary wedges are formed at convergent plate boundaries where two tectonic plates collide. The leading edge of the subducting plate is scraped off and accumulates at the overriding plate, creating a wedge-shaped structure. This process can lead to the formation of mountain ranges and deep-sea trenches.

What is an accretionary wedge?
An accretionary wedge is a geological formation that occurs at a convergent plate boundary, where two tectonic plates collide. It forms when sediments and rocks are scraped off the subducting plate and are thrust up and over the overriding plate. Accretionary wedges are typically found in subduction zones and can create complex geological features such as fold and thrust belts.
What structure is formed when ocean crust subducts below continental crust?
A deep ocean trench is formed when ocean crust subducts below continental crust. The descending oceanic plate is forced down into the mantle by the more buoyant continental plate. This process can also lead to the formation of volcanic arcs on the overriding plate.
Where was the wedge found?
Wedges have been found in various archaeological sites all around the world, dating back thousands of years. Some notable areas where wedges have been discovered include Mesopotamia, Egypt, and ancient China.
What feature is formed in a convergent boundary?
If you're looking at a convection zone along coastal areas you'll look for subduction zones, trenches, accretionary wedges, volcanic activity, seismic activity, mountain building activity, island creation (think Japan), and possibly exotic terrains to name a few. If you're looking at convergent boundaries on continental land you'll generally find mountain building (think Himalayas), faulting, and seismic activity; not as much volcanism here since the crust is even think to support the mountain zone. There isn't specifically one feature to be found because you have three options for convergent boundaries: continental-oceanic, continental-continental, and oceanic-oceanic.
What is an accumulation of different sedimentary and metamorphic rocks combined with scraps of ocean crust called?
That would be a melange, a type of rock formation where various types of rocks are mixed together in a chaotic manner. Melanges are typically found in tectonically active regions where intense folding and faulting has occurred.

What is an accretionary prism?
An accretionary prism is an alternative name for an accretionary wedge, the accumulation of sediment formed by an oceanic plate and a tectonic plate, as it is scraped from the top of the oceanic plate.

How does acretionary wedges form?
Accretionary wedges form at convergent tectonic plate boundaries, where an oceanic plate subducts beneath a continental or another oceanic plate. As the subducting plate descends, sediments and materials on the ocean floor accumulate and are compressed against the overriding plate. This process results in the uplift and deformation of sediments, creating a wedge-shaped structure. The continuous addition of sediment and tectonic forces contributes to the growth and evolution of the accretionary wedge over time.
What is an accumulation of ocean floor sediment formed at convergent boundaries?
This is known as an accretionary wedge or prism. Please see the related link.
Besides volcanic or built-up coral find another way island are formed?
Islands can be formed from glacial till, from the rifting apart of continents, and out of material built up along a subduction zone (accretionary prism). Some islands are man made.
What evidence suggests that the moon was not formed from an accretionary disc?
One piece of evidence that suggests the moon was not formed from an accretionary disc is the similarity in isotopic composition between the Earth and the moon. If the moon had formed from an accretionary disc, it would likely have a different isotopic composition than the Earth.
What do wedges do?
wedges can slice, pin or wedge into something.

What are the models of wedges that ben hogan made?
Ben Hogan made gap wedges, log wedges and sand wedges. A pitching wedge is also available from Ben Hogan but these are usually included in the irons.
