A string of small volcanic islands is most likely to form at a convergent ocean-ocean boundary.
To determine at which type of plate boundary a string of small volcanic islands would most likely form, we need to understand the different types of plate boundaries.
1. Convergent ocean-land boundary: This occurs when an oceanic plate collides with a continental plate. When the denser oceanic plate subducts beneath the less dense continental plate, it can create a trench and a volcanic arc. However, this typically forms larger landmasses rather than a string of small volcanic islands.
2. Divergent ocean-ocean boundary: This occurs when two oceanic plates move away from each other. As they separate, magma rises to fill the gap, creating new oceanic crust. This process can result in the formation of underwater volcanoes and volcanic islands. These volcanic islands can form a chain, representing a string of small volcanic islands.
3. Convergent ocean-ocean boundary: This occurs when two oceanic plates collide. Similar to the convergent ocean-land boundary, subduction takes place, forming a trench and a volcanic arc. However, this type of boundary also has the potential to create volcanic islands along the edges of the arc, resulting in a chain of small volcanic islands.
4. Transverse boundary: This occurs when two plates slide past each other horizontally. While this type of boundary does not typically lead to the formation of volcanoes or volcanic islands, it can produce earthquakes due to the friction between the plates.
Based on the options given, the correct answer would be the "convergent ocean-ocean boundary." This is the type of plate boundary where a string of small volcanic islands is most likely to form.
