ocean crust is denser
an example of this is the marinas trench of the coast of japan and the continental plate of the Philippine's. the more denser oceanic plate is forced under by the lighter continental plate. this normally happens at destructive plate margins.
This phenomenon, known as subduction, occurs because oceanic plates are denser and thinner than continental plates. When the two plates collide, the denser oceanic plate is forced beneath the less dense continental plate due to gravitational pull. This process results in the oceanic plate descending into the mantle, leading to the formation of deep ocean trenches and volcanic arcs.
This process is known as subduction. As the heavier sea plate is forced beneath the lighter continental plate, it can create deep-sea trenches and can lead to volcanic activity on the Earth's surface. Subduction zones are often associated with seismic activity, including earthquakes.
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.
Divergent boundaries -- where new crust is generated as the plates pull away from each other.Convergent boundaries -- where crust is destroyed as one plate dives under another.Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.
Ocean crust is denser
Because of its higher density, and gravity. One part of plate tectonic theory.
The ocean crust dives below the continental crust due to a collision. This collision involves the two types of crust and since the oceanic crust is denser, it sinks to the bottom while the less dense continental crust rises to the top.
Yes, it "dives" under the continental crust and back into the mantle.
it dives into a continental slope
it dives into a continental slope
When two tectonic plates collide, the crust becomes compressed and thickened due to the intense pressure. This compression can cause the crust to buckle and push upwards, leading to the formation of mountain ranges. Over time, this continuous collision and compression can result in the thickening of continental crust at these boundaries.

These areas are called subduction zones. Subduction occurs when the oceanic plate is forced beneath the continental plate due to differences in density, leading to the formation of deep oceanic trenches and volcanic arcs on the overriding plate. This process is a key driver of plate tectonics and the formation of mountain ranges and volcanic activity.
