What explains the observation that when a continental and oceanic plate collide the oceanic plate dives down under the continental plate?
The oceanic plate must be more dense than the continental plate for this to happen.
A process that occurs when a heavier sea plate dives beneath a lighter continental plate?
Subduction :D I'm barley 14
What is the process where a heavier sea plate dives beneath a lighter continental plate is called?
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.
What are the 4 plate boundries?
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.
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.
Ocean crust dives below continental crust because?
Ocean crust is denser
Ocean crust dives below continental crust because of what?
Because of its higher density, and gravity. One part of plate tectonic theory.
Why does ocean crust dive below continental crust?
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.
When plates collide with continental plates does the denser ocean plate sink?
Yes, it "dives" under the continental crust and back into the mantle.
Where the leading edges of the oceanic plate encounter the margins of continental plates head on the denser oceanic crust dives beneath the lighter continental crust forming areas called?
Subduction zones.
Why is continental crust thickest at collision boundaries?
1. One of the plates dives under the other so you have two thickness's of crust material on top of each other.
What happens at the end of a continental shelf?
it dives into a continental slope
What happens at the end of the continental shelf?
it dives into a continental slope

A doplin dives to 24feet how many fathoms is below the surface?
4. A fathom being 6ft
