What happens when tectonic plates of more density and less density collide?

Whenever two oceanic plates collide, one will be older, thus colder, and more dense. This plate will slide under the newer, less dense plate and again, a subduction zone will form creating volcanoes arising from the ocean, called a volcanic arc.

What happens when one tectonic plate is denser than another?

Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate. The plate being forced under is eventually melted and destroyed. Island arcs and oceanic trenches occur when both of the plates are made of oceanic crust.

What happens when two tectonic plates of similar density and composition collide?

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.

When two old tectonic plates collide Both of them have a density that is much lower than the mantle?

Convergent Plate Boundary – Continental The two thick continental plates collide, and both of them have a density that is much lower than the mantle, which prevents subduction (there may be a small amount of subduction, or the heavier lithosphere below the continental crust might break free from the crust and subduct).

What happens when 2 plates carrying oceanic crust collide?

When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.

When two tectonic plates collide the oceanic crust usually Subducts?

When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.

What happens to the thinner and denser oceanic plate when it collides with the thicker and less dense continental plate What process do they undergo?

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. The subducting plate causes melting in the mantle.

What tectonic plates have the same density?

A convergent boundary forms when two continental plates collide. Neither plate subducts because the crusts have approximately the same density.

What occurs when two plates come together and the denser one is forced under back into the mantle?

Moves the lithosphere in opposite directions AWAY from the mid-ocean ridge. When tectonic plates collide, the denser plate will sink into the mantle along a subduction zone. This plate is called a SLAB. Because the slab is old and cold, it is denser than the surrounding mantle and will sink.

What happens when two moving plates of earth crust collide head on with each other?

What happens when two moving plates of earth’s crust collide head-on with each other? When two plates collide head-on, they push each other up and form mountains. The Himalayas and other great mountain ranges were created by this process.

What happens when two plates carrying oceanic crust collide quizlet?

What happens when oceanic crust collides into oceanic crust? The plate that is more dense sinks under the other plate. The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle.

What happens when two plates of different densities collide?

When two tectonic plates of different densities collide due to convection currents that are produced by the heat within the asthenosphere, a plate boundary (convergent) is formed. Deep trenches are usually formed where one of the plates slides beneath each other (a process called subduction). Trenches are elongated and often narrow cavity.

When an oceanic plate and a continental plate collide?

When an oceanic plate and a continental plate collide. Trench and volcano could form at the plate boundary. When two tectonic plates of different densities collide due to convection currents that are produced by the heat within the asthenosphere, a plate boundary (convergent) is formed.

How are trenches and volcanoes formed at plate boundaries?

Trench and volcano could form at the plate boundary. When two tectonic plates of different densities collide due to convection currents that are produced by the heat within the asthenosphere, a plate boundary (convergent) is formed. Deep trenches are usually formed where one of the plates slides beneath each other (a process called subduction).

Which two types of landforms could form at a plate boundary?

The answer is Trench and Volcano, because when two plates of different densities collide. When an oceanic plate and a continental plate collide. Trench and volcano could form at the plate boundary.
