Volcanoes at the boundaries where two oceanic plates collide will create a string of islands called an archipelago. An archipelago is also linked by land areas that are below the sea.
Two landforms created by oceanic-oceanic crust interactions are oceanic ridges and volcanic islands. Oceanic ridges form at divergent plate boundaries where two oceanic plates move apart and magma rises to create new crust. Volcanic islands, on the other hand, form where two oceanic plates converge and one plate subducts beneath the other, leading to volcanic activity and the formation of islands.
An island arc is typically found along convergent tectonic plate boundaries, where an oceanic plate subducts beneath another oceanic plate. This process leads to volcanic activity, resulting in the formation of a chain of islands. Notable examples include the Aleutian Islands in Alaska and the Mariana Islands in the western Pacific Ocean. These arcs are characterized by a series of volcanoes and deep ocean trenches.
Volcanic island arcs are typically associated with convergent plate boundaries, specifically where an oceanic plate subducts beneath another oceanic plate. This subduction process generates magma, which can rise to the surface, forming a chain of volcanic islands. Examples of volcanic island arcs include the Aleutian Islands in Alaska and the Japanese Archipelago.
The Aleutian Islands
An oceanic plate can descend beneath another oceanic plate - Japan, Indonesia, and the Aleutian Islands are examples of this type of subduction. Alternately, an oceanic plate can descend beneath a continental plate - South America, Central America, and the Cascade Volcanoes are an example of this type of subduction.

Some Islands are parts of continents (high points in the continental shelf) eg The British Isles. Some Islands are parts of continents that have become detached during continental drift (eg Seychelles or Madagascar) Some Islands are unrelated to continents and result from oceanic plate processes (eg Hawaii). Some Islands are a result of the interaction between continental and oceanic plates (eg some of the Caribbean Islands, Japan and Cyprus).
The Mariana Islands
Some non-examples of archi the US Virgin Islands, the British Virgin Islands, and the Dutch Virgin Islands. To this list, you can add the Hawaiian Islands as well.

The motto of Oceanic Platform of the Canary Islands is 'to promote sustainability and long-term observation of the ocean'.
The two main types of islands are continental islands, which are formed from the same landmass as a nearby continent, and oceanic islands, which are formed from underwater volcanic activity or coral reefs. Continental islands tend to be larger and closer to continents, while oceanic islands are typically smaller and more isolated.

Oceanic Eden is 10 thousand islands scattered over the pacific ocean.
