What happens if an oceanic to oceanic happens?
When an oceanic to oceanic happens, two oceanic plates converge and one of the plates subducts into a trench. The subducted plate sinks down into the mantle and begins to melt. Molten rock from the plate rises toward the surface and forms a chain of volcanic islands, also called a volcanic island arc, behind the trench in the ocean.
What is the name of ocean crust?
The name of the crust beneath the oceans is called "oceanic crust." It is thinner and younger than continental crust and primarily composed of basaltic rocks.
What is the thinest part of the earths crust under the ocean called?
The thinnest part of the Earth's crust under the ocean is called the oceanic crust. It typically ranges from about 5 to 10 kilometers thick, making it significantly thinner than continental crust, which can exceed 30 kilometers in thickness. The oceanic crust is primarily composed of basalt and is formed at mid-ocean ridges through volcanic activity.
Volcanoes at boundaries where two oceanic plates collide create a string of islands called?
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.
The oceanic crust is made up mostly of dense rock called what?
The oceanic crust is mostly made up of basalt, which is a dense volcanic rock that forms from the cooling of lava at the Earth's surface.
What is the crust beneath the ocean called?
The crust beneath the ocean is called oceanic crust. It is thinner and younger than continental crust, primarily composed of basaltic rock formed at mid-ocean ridges through volcanic activity.

When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms what?
This type of boundary is called a convergent boundary or subduction zone, where the oceanic plate is pushed beneath the continental plate. The descending oceanic plate melts due to the heat and pressure, leading to volcanic activity and the formation of volcanic arcs.
What is the subduction zone called when a oceanic and continental plate converge?
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.
What is the name of ocean crust?
The name of the crust beneath the oceans is called "oceanic crust." It is thinner and younger than continental crust and primarily composed of basaltic rocks.
What are the volcanic landforms at divergent ocean plate boundaries called?
Volcanic landforms at divergent ocean plate boundaries are called mid-ocean ridges. These ridges form where tectonic plates are moving away from each other, allowing magma to rise up and create new oceanic crust. They are characterized by volcanic activity and the formation of underwater mountain ranges.

The thinnest part of the Earth's crust under the ocean is called the oceanic crust. It typically ranges from about 5 to 10 kilometers thick, making it significantly thinner than continental crust, which can exceed 30 kilometers in thickness. The oceanic crust is primarily composed of basalt and is formed at mid-ocean ridges through volcanic activity.
What is a string of volcanoes along an ocean to ocean convergent boundary?
A string of volcanoes along an ocean-to-ocean convergent boundary is called a volcanic island arc. This forms when one oceanic plate subducts beneath another oceanic plate, leading to volcanic activity along the subduction zone. Examples include the Aleutian Islands in Alaska and the Japanese archipelago.
A dark small grained volcanic rock commonly seen in oceanic eruptions?
That is most likely to be Basalt, also called bluestone
Volcanoes at boundaries where two oceanic plates collide create a string of islands called?
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.

The oceanic crust is mostly made up of basalt, which is a dense volcanic rock that forms from the cooling of lava at the Earth's surface.
Which type of landform develops at plate boundaries where one oceanic plate descends beneath another?
A trench or subduction zone develops at plate boundaries where one oceanic plate descends beneath another. This process is called subduction and typically results in the formation of deep oceanic trenches and volcanic arcs due to melting of the descending plate.
