What would be the result of a collision between continental plates in which one plate is forced down toward the heat of the mantle?
A collision between continental plates, where one plate is forced down into the mantle, typically results in the formation of a subduction zone. This process can lead to intense geological activity, including earthquakes and volcanic eruptions, as the descending plate melts and interacts with the mantle. Over time, it may also contribute to mountain building and the creation of deep ocean trenches. The region may experience significant deformation and metamorphism of rocks due to the immense pressure and heat involved.
What else can I help you with?
Why does oceanic lithosphere sub duct while continental lithosphere does not?
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
What would happen to mantle convection currents beneath a continental-continental convergent boundary?
Mantle convection currents beneath a continental-continental convergent boundary would likely be disrupted and deflected due to the collision of the continental plates. This collision would create intense compression and thickening of the crust, altering the flow patterns and direction of the mantle convection currents in the affected region.
What occurs in earths mantle hich causes mountains to form?
Mountains form primarily due to tectonic activity in Earth's mantle, particularly through processes like continental collision and subduction. When tectonic plates collide, one plate can be forced upward, leading to the formation of mountain ranges. Additionally, magma from the mantle can push through the crust, creating volcanic mountains. These processes are driven by the convection currents in the mantle, which facilitate the movement of tectonic plates.
Why does oceanic plate always slide under a continental plate what they collide?
Oceanic plates are denser and thinner than continental plates, which allows them to subduct or slide beneath the continental plates during a collision. This subduction occurs because the denser oceanic crust is forced down into the mantle, leading to the formation of deep ocean trenches and volcanic arcs. Additionally, the buoyancy of the thicker continental crust prevents it from being subducted in the same way.
What type of structure has formed where the Jaun de Fuca plate is subducting beneath the North American plate?
The Nazca Plate and the South American Plate are colliding. Because oceanic plates like the Nazca are more dense than continental plates, they are forced below the continental plate and subduct, or flow downward into the mantle at varying degrees of descent from the area of collision!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
How were the Andes in South America formed?
The Andes are formed by the collision of the Nazca Plate (oceanic) and the South American Plate (continental). The collision causes the continental crust to buckle and form fold mountains which are then peppered with volcanoes caused by melting of the Nazca plate as it is forced down into the Earth's mantle.

When continental plates collide what happens to the oceanic crust between them?
When continental plates collide, the denser oceanic crust is usually subducted beneath the less dense continental crust. This process can create subduction zones, where the oceanic crust is forced downward into the mantle. The oceanic crust may melt or be recycled back into the mantle in these subduction zones.
What is the area between the mantle and core where hot rocks forced into the crust?
The area is known as the mantle transition zone and it is located between the upper mantle and the lower mantle. This region is characterized by high pressures and temperatures, causing rocks to undergo changes in their physical and chemical properties.

What are the two ways plates converge?
There are two basic types of convergent boundary. The first is a subduction zone, which occurs at a collision between two plates carry oceanic crust or one carrying continental and once carrying oceanic crust. In such a collision, one oceanic plate will subduct under the other and sink into the mantle. Such a collision produces volcanoes on the overriding plate and will produce mountain ranges on a continent. The other type of convergent boundary occurs when two continent collide. These collisions produce high mountains but not volcanoes. No subduction occurs as continental crust is not dense enough to sink into the mantle.
What drives the motion of the continental plates on Earth?
The motion of the continental plates on Earth is primarily driven by the process of mantle convection. Heat from Earth's core causes the rock in the mantle to slowly move, creating convection currents that push and pull the plates along with them. This movement leads to the drifting and collision of the plates, shaping the Earth's surface over millions of years.
What happens when plates collide and one plate sinks?
The collision of plates commonly includes "subduction", where one plate is forced under the other, down into the mantle. These plates are melted and rise again, adding to the magma under the overlying plate. This creates heated rock that can later emerge through the surface in volcanoes. Oceanic plates are thinner and denser than continental plates, so are the ones forced down, either under a continental plate or another oceanic plate.
Collisions between Earth's plats push rock down toward the heat of Earth's?
Plates* but I know you just made a mistake... anyway I found the answer in my science book from school.I believe it is in the mantle because this is what it said:The collision of continental plates produces faults, folds, and uplift of the crust. Eventually, the collision could push up a mountain range. Then, erosion begins. The mountains eventually are worn away, leading to the formation of sedimentary rock.A collision between continental plates can also push rocks down deep into the mantle. There, heat and pressure could change the rocks to metamorphic rock. And so the rock cycle continues, for hundreds of millions of years.(Btw i bolded the mantle part, not the book)
