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 else can I help you with?
A convergent boundary causes what stress type?
A convergent boundary causes compressional stress.
At a reverse fault what force pushes on rocks from opposite directions?
In a reverse fault, compressional forces push rocks from opposite directions, causing the rocks to move vertically along the fault plane. The hanging wall moves up relative to the footwall due to this compressional force.
What type of plate boundary causes shear stresses?
Shearing stress is one of three kinds of stresses. Compressional and tensional are the others. Shearing stress is associated with transform. The other two kinds of plate boundaries are convergent and divergent.
What is a compressional wave?
Answer 1: A compressional wave is a wave that is close together and transverse waves are waves that are going the way the wave travels. Answer 2: Basically, it's a sound wave. A compressional wave is a wave that travels back and forth, moving with compression. Scince it is a mechanical wave it must use a medium to travel though. A sound wave is a good example of a compressional wave. A compressional wave is a wave that travels back and forth, moving with compression.

How folded rocks primarily the result of compressional or tensional forces?
Folded rocks are primarily the result of compressional forces. When compressional forces act on rocks, they deform and buckle, leading to the formation of folds. Tensional forces, on the other hand, tend to result in the stretching and fracturing of rocks rather than folding.
A convergent boundary causes what stress type?
A convergent boundary causes compressional stress.
What is stress at a convergent plate?
The type of stress developed at a convergent boundary is Compressional Stress.
What kind of stress occurs at a converging boundary?
Compressional stresses occur at convergent plate boundaries.
Is a compressional wave mechanical or compressional?
compressional
Is a compressional wave a sound wave?
Compressional!
What is found in a compressional wave?
A rarefaction is found in a compressional wave
What are compressional boundarys?
A compressional bounday is plate boundarys that are being compressed
Is a sound wave compressional or transverse?
A sound wave is a compressional wave, which means the particles in the medium vibrate parallel to the direction of the wave propagation. This compression and rarefaction of particles create the variations in pressure that we perceive as sound.
Are water waves compressional waves?
Compressional waves are waves that produce compression and rarefaction when traveling through a medium. Water waves are not considered as compressional waves.
What is compressional stress?
Compressional stress is the stress produced by two tectonic plates moving towards each other.
Are sound waves transverse waves or compressional waves Why?
Compressional, gasses can be compressed but cannot be wiggled side to side.
What spread apart portion of a compressional wave?
The spread-apart portion of a compressional wave is called a rarefaction. In a compressional wave, particles are pushed together (compression) and then spread apart (rarefaction) as the wave passes through a medium.
