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.
Hot spots can occur in both oceanic and continental crust, not just in oceanic crust. They are caused by plumes of hot material rising from deep within the Earth's mantle, which can create volcanic activity. While many well-known hot spots, like the Hawaiian Islands, are located in oceanic regions, others, such as the Yellowstone hotspot, are found beneath continental crust. Therefore, hot spots are not limited to oceanic crust alone.
Island arcs are formed by the subduction of an oceanic plate beneath another oceanic plate. The oceanic plate that is subducted beneath the other plate melts as it is pushed down into the mantle and creates a source of magma. The magma rises and forms volcanoes which create the islands of the island arc. The Hawaiian islands are formed by a mantle plume which is roughly in the center of the Pacific plate. The plate is moving across the plume and the islands are being formed in a line as the plate moves. The Hawaiian islands don't count as an island arc because they are formed in a completely different process and because they are roughly in a line, not an arc.
oceanic convergence is when two oceanic plates subduct beneath one another.

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.

Subduction zones occur at plate boundaries where one oceanic plate descends beneath another. This process leads to the formation of deep oceanic trenches, volcanic arcs, and earthquakes due to the intense pressure and heat generated by the subduction of the oceanic plate.

They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.
In Hawaiian, "deep sea" is translated as "kai hohonu." The word "kai" means sea or ocean, while "hohonu" means deep. This phrase reflects the rich connection of the Hawaiian language to the oceanic environment surrounding the islands.
