# What happens when a two plates carrying oceanic crust collide?

## What happens when a two plates carrying oceanic crust collide?

A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. Earthquakes generated in a subduction zone can also give rise to tsunamis.

What happens when two plates carrying oceanic crust collide quizlet?

When two plates carrying oceanic crust collide the more dense crust sinks under the less dense one and creates a trench. When two continental plates collide they form mountain ranges and volcanoes.

### What happens when two plates past each other?

When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.

What happens when two plates of the same density collide?

When two plates (either oceanic or terrestrial) converge and they are of similar density then they will crash into each other and form mountains. A great example of this is when India crashed into the Asian continent and the Himalayas were formed.

#### When 2 plates collide what determines which plate comes out on top?

When two plates converge, the result is called a collision. There are two types of Convergent Boundaries: Convergent Subduction and Convergent Collision. Convergent Subduction: When two plates collide, the density of the plates determines which one comes out on top. Oceanic crust is more dense than continental crust.

What happens when a plate made of continental crust collides with a plate made of oceanic crust?

When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches (figure 6).

## What geological process will occur if oceanic crust collides with continental crust?

When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches (figure 6). The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.

What will happen if two oceanic plates move away from each other?

When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created. When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created.

### What happens when two plates collide for kids?

Plate Movements At one type of boundary the plates slide alongside each other. At another type, the plates crash into each other. In this case the edge of one plate may slide under another plate and be destroyed. Or the two edges of the plates may rise up and form mountains.

When two plates collide that are similar density which plate boundary will result?

A convergent boundary forms when two continental plates collide. Neither plate subducts because the crusts have approximately the same density. Instead, the rocks are smashed together causing them to recrystallize due to the intense heat and pressure from the colliding plates.

#### What happens when two continental plates crash into each other?

When two continental plates crash into each other, they crumple and fold. The crust is forced up, and mountains form, and earthquakes happen.

What is formed when one oceanic plate moves under another?

An island arc results when one oceanic plate moves under another oceanic plate. A continental arc results when an oceanic plate moves under a continental plate. Volcanoes and volcanic activity often occur as a result of the subduction process because the subducting slab releases liquids as it moves into the extreme temperatures of the mantle layer.

## What happens when two oceanic plates converge/meet?

When two oceanic plates collide, their densities help to determine the one that will appear on top of the other. And as you already know, the oceanic crust does become denser and colder when it spreads out of the mid-ocean ridge. So, when two oceanic plates conveying oceanic crust collides at a trench, the denser one will come under the less dense plate . That is what happens when oceanic plates meet.

What happends when two plates of the same density collide?

Formation convergent boundaries. A tectonic plate boundary always forms when two continental plates collide. Neither plate subducts because the crust have approximately the same density. Instead, the rocks are smashed together causing them to recrystallize due to the intense heat and pressure from the colliding plates.
