What happens when a continental plate collides with another continental plate?

At convergent boundaries, where plates push together, crust is either folded or destroyed. When two plates with continental crust collide, they will crumple and fold the rock between them. A plate with older, denser oceanic crust will sink beneath another plate. The crust melts in the asthenosphere and is destroyed.

When oceanic plate and continental plate collide what type of land form will be created?

The compressional forces stemming from a convergent plate boundary, where two plates collide with one another, can create fold mountains. This may involve the collision of two continental plates or a continental plate and oceanic plate, forcing sedimentary rocks upwards into a series of folds.

When an oceanic and a continental plate meet?

Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches. The descending end of the oceanic plate melts and creates pressure in the mantle, causing volcanoes to form.

What happens if two oceanic plates collide?

When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.

What happens when an oceanic plate converges with a continental plate *?

When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. … As time goes on the hot magma rising upward from the subduction zone causes further compression of the mountain belt.

What happens to oceanic crust as it collides with continental crust?

Oceanic Crust is more dense than Continental Crust When they collide, the Oceanic crust sinks below the continent. As it sinks, it heats up at the edge of the mantle and begins to melt.

What happens when continental and oceanic crust collide?

When they collide, the Oceanic crust sinks below the continent. Some of this crust joins the mantle, but lighter materials will rise up through the continent to emerge on the surface as volcanoes, melting some continental crust with it on the way up.

What is formed when the oceanic plate collides?

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. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.

What happens when two continental plates crash into each other?

The Crash!: The Crash! What happens when plates crash into each other depends on the types of plates involved. Because continental crust is lighter than oceanic crust, continental plates ”float” higher. Therefore, when an oceanic plate meets a continetnal plate, it slides under the lighter plate and down into the mantle.

What is formed when one oceanic plate moves under another?

As the two move apart, mid-ocean ridges are created as magmafrom the mantle upwells through a crack in the oceanic crust and cools. This, in turn, causes the growth of oceanic crust on either side of the vents. As the plates continue to move, and more crust is formed, the ocean basin expands and a ridge system is created.

What happens when two plates of different densities collide?

Depending on the type of plates that collide, they either lift or subduct. When an oceanic plate collides with a continental plate, it typically slides underneath it. If two like plates collide, they crush together at the collision point and lift up broken material from both plates.

What landform is created when two oceanic plates collide?

If an oceanic plate and a continental plate collide (a continental plate is a tectonic plate that holds land/continents), the oceanic plate will go under the continental plate and goes into the mantle. If two continental plates collide, the crust thickens and is forced to create landforms such as mountains.
