When oceanic plates move beneath continental plates in a process called subduction, the high pressure and high temperatures in the Earth's mantle cause the rock in the subducting plate to melt. This molten rock, or magma, then rises to the surface through volcanic activity, leading to the formation of volcanic arcs and chains.

What happens at a convergent plate boundary between an oceanic and continental plate?
At a convergent plate boundary between an oceanic and continental plate, the oceanic plate is usually denser and subducts beneath the continental plate. This can lead to the formation of deep oceanic trenches, volcanic arcs on the continental plate, and earthquakes due to the intense pressure and friction. Over time, the oceanic plate can melt and create magma that rises to form volcanic mountain ranges on the continental plate.
How are mountains formed when a plated with an oceanic crust meets one with a cnotinental crust?
The oceanic plate is more dense than the continental plate, and will subduct, or move underneath, the lighter continental plate. The result is that the continental plate is uplifted. As the oceanic crust goes deeper and deeper, the temperatures become higher, causing the subducting crust to eventually melt into the mantel. The heat and gas pressure from the melting of the subducting crust may eventually seek release in the form of a volcano. The rate of crustal movement is slow, measured in a small number of inches per year, but the volcanism and crustal uplifting and folding eventually create mountains.
What happens to oceanic crust at a deep ocean trench?
At deep ocean trenches, oceanic crust is subducted beneath an overriding tectonic plate. As the oceanic crust is forced downward into the mantle, it undergoes intense heat and pressure, causing it to melt and contribute to the formation of volcanic arcs and earthquakes.
What happens when continental plates collide?
This is called a constructive plate boundry. The oceanic plate will be pushed under by the continental plate, as it as thinner and denser. The friction can result in earthquakes and the heat from the friction will melt some of the oceanic plate. The pressure in the mantle will push the magma up to the surface, creating a volcano (creating land, therefore "constructive"). Hope this helped, just recently did tectonics in geography class.
What is a compressional boundary?
When an oceanic plate and a continental plate move towards each other the denser oceanic plate dives under the lighter continental one creating a deep ocean trench.As the oceanic plate goes deeper into the mantle, increased temperature and friction cause it to melt creating a subduction zone.Newly molten rock is lighter than the surrounding rock so it rises through the crust towards the surface.If molten rock (magma) reaches the earth's surface it may spread out along a fault line or it may erupt at a single point as a volcano.Example of an oceanic plate colliding with a continental plate is where the Pacific plate moving towards the South American plate at a rate of 9 centimetres per year.
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.
Does oceanic plate melt and cause volcanoes to erupt when slides under continental plate?
yes that's right

When two plates come together?
They fold up when there continental, creating mountains and steep hills. The Rocky's are a great example. Oceanic plate collisions cause tsunamis, and Oceanic plates are subducted under Continental plates, they are overlapped by the continental plate.
A is where an oceanic plate slides down into the asthenosphere?
A is called a subduction zone, where an oceanic plate converges with another tectonic plate, typically a continental plate, and is forced down into the asthenosphere. This process can lead to the formation of deep ocean trenches and volcanic arcs. The intense pressure and heat in the asthenosphere can cause the subducting plate to partially melt, contributing to magma formation and volcanic activity. Subduction zones are key areas for understanding plate tectonics and associated geological phenomena.
What mountain range has an oceanic plate and continental plate colliding?
Fold mountains.
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
Which boundaries are likely to result in volcanic island arcs?
Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.
Where do subduction boundarys occur?
Subduction boundaries occur where one tectonic plate sinks below another, typically in oceanic-continental or oceanic-oceanic plate interactions. These boundaries are associated with deep ocean trenches, volcanic arcs, and earthquakes due to the collision and subduction of the plates. Examples include the boundary between the Pacific Plate and the North American Plate along the west coast of South America.
How convergent continental crust can lead into oceanic plates?
Convergent continental crust can lead to the formation of oceanic plates through a process called subduction. When two tectonic plates collide, the denser oceanic plate is forced beneath the less dense continental plate, creating a subduction zone. As the oceanic plate descends into the mantle, it can partially melt and contribute to volcanic activity on the continental crust. Over time, this process can lead to the creation of new oceanic crust as the material is recycled and reformed.
How are mountains formed when a plated with an oceanic crust meets one with a cnotinental crust?
The oceanic plate is more dense than the continental plate, and will subduct, or move underneath, the lighter continental plate. The result is that the continental plate is uplifted. As the oceanic crust goes deeper and deeper, the temperatures become higher, causing the subducting crust to eventually melt into the mantel. The heat and gas pressure from the melting of the subducting crust may eventually seek release in the form of a volcano. The rate of crustal movement is slow, measured in a small number of inches per year, but the volcanism and crustal uplifting and folding eventually create mountains.
How are volcanoes formed by tectonic plates?
Plate tectonics can lead to volcanic activity in two ways. Where two tectonics plates pull apart, the crust becomes thinner, which decreases pressure on the upper mantle and allows rock the melt and move to the surface. At subduction zones, where a plate collision forces oceanic crust into the mantle, seawater dragged down with the plate alters the chemistry of the mantle rock, allowing it to melt at a lower temperature.
