If an island is on a subducting plate and close to the area of subduction, it will gradually sink as it moves towards the trench.

If the island is on the plate under which the other plate is subducting, it will experience many earthquakes and volcanic eruptions.

Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.

What lanforms do you get when two plates subduct?

When two plates subduct, the overriding plate may develop volcanic arcs due to melting of the subducting plate, often forming chains of volcanoes. Additionally, deep ocean trenches can form at the boundary where the two plates converge and subduct. Collision zones and fold mountain ranges can also develop as a result of the intense tectonic forces between the plates.

Do both islands and continents move?

Yes they are both above the Tectonic plates therefore follow tectonic movements


What is the Amount of mass in a given volume it determines which plate will subduct at convergent boundaries?

At convergent boundaries, the amount of mass in a given volume, known as density, determines which tectonic plate will subduct. Typically, oceanic plates are denser than continental plates, so when they converge, the denser oceanic plate sinks beneath the lighter continental plate. This process is influenced by factors such as temperature, composition, and the age of the plates, with older oceanic crust generally being denser and more likely to subduct.


What happens where tectonic plates move part?

An earthquake. But while this happens the magma fills the gap.


What happens when two plates tectonic move toward each other and smash together?

When two tectonic plates move toward each other and smash together, it can lead to the formation of mountain ranges, earthquakes, and volcanic activity. The collision can cause the plates to crumple, fold, or subduct beneath one another, depending on their density and composition. This process is known as plate convergence and plays a significant role in shaping Earth's geology.


What is a result of gravity in relation to tectonic plates?

Gravity plays a crucial role in the movement of tectonic plates by influencing their buoyancy and stability. It causes denser oceanic plates to subduct beneath lighter continental plates at convergent boundaries. Additionally, gravity drives the process of isostasy, where the lithosphere adjusts to balance the weight of geological features, leading to tectonic activity such as earthquakes and volcanic eruptions. Overall, gravity is a fundamental force that shapes the dynamics of plate tectonics.


What way do tectonic plates move to form islands?

Tectonic plates move in various ways, one being through the process of subduction where one plate is forced beneath another. This movement can lead to volcanic activity, creating islands as magma rises to the surface and solidifies. Additionally, plates can also move apart at mid-ocean ridges, allowing magma to rise and form new land.


Why does the oceanic plate subduct and the continent doesn't?

Oceanic plates are denser than continental plates due to their composition and age. When two plates collide and one is denser, the denser plate will subduct beneath the less dense plate. This is why oceanic plates subduct beneath continental plates in a process known as subduction.
