This would depend on the type of boundary: ocean-ocean, continent-continent, or ocean-continent. For ocean-ocean crusts, the slab of crust "forced down" is being subducted. Besides bringing water inside the rock and lowering its melting temperature, this could produce an ocean trench. For continent-continent convergence, the "subducted" plate does not go very far. Because of the buoyancy of continental crust and its lightweight nature (as compared to oceanic crust, which is very dense), the plates tend to buckle and create tall mountain ranges. For continent-oceanic convergence, such as the Western cost of South America, oceanic crust is forced down and is subducted underneath continental crust. This creates mountain ranges as well, and also forms the mechanism from which igneous intrusions can make their way to the surface of the crust.
What else can I help you with?
Which theory of plate movement relies on weight of the subducting crust?
Slab pull theory relies on the weight of the dense, oceanic crust sinking into the mantle at subduction zones. As the crust descends, it pulls the rest of the tectonic plate along with it, driving plate movement.
How does faulting of the earth's layer occur?
Faulting of the Earth's layers occurs when stress builds up within the crust, leading to the rock breaking and sliding along a fault plane. This movement releases energy in the form of an earthquake. Faulting can happen due to tectonic plate movements, volcanic activity, or regional stress within the Earth's crust.
A slab of continental or oceanic crust is known as?
A slab of continental or oceanic crust is known as a tectonic plate. These plates make up the Earth's lithosphere and float on the semi-fluid asthenosphere below, moving due to the process of plate tectonics.
Where oceanic crust collides with continental crust is the?
subduction zone. In this area, the denser oceanic crust is forced beneath the less dense continental crust, leading to the formation of deep ocean trenches and volcanic mountain ranges. This collision can also cause intense seismic activity and the potential for tsunamis.
What is the slab of the earths crust that regularly moves away from or collides with other slabs called?
The slab of the Earth's crust that regularly moves away from or collides with other slabs is called a tectonic plate. These plates make up the Earth's lithosphere and their movement is responsible for processes such as earthquakes and mountain formation.

How water can help form a volcano?
Water will be brought down with the subducting slab and it will lower the melting temperature of the rock, therefore making it easier to make a volcano. Again, that's very simplified, but its effectively that.

What are plates in science?
An extremely large, moving slab of rock that forms Earth's crust.

All tectonic plates are part of the Earth crust.

What type rock can form magma andesitic?
Andesitic magma typically forms in subduction zone environments, where oceanic crust is forced beneath continental crust. This process leads to the melting of both the subducting slab and the overlying mantle, resulting in the generation of andesitic magma. The primary rock types associated with this process are basaltic rocks, which can partially melt and contribute to the formation of andesitic magma through fractional crystallization and mixing with other magma types.
Where oceanic crust collides with continental crust is the?
subduction zone. In this area, the denser oceanic crust is forced beneath the less dense continental crust, leading to the formation of deep ocean trenches and volcanic mountain ranges. This collision can also cause intense seismic activity and the potential for tsunamis.
How earths crust move?
Earth's crust and the solid rocky and brittle upper mantle are known as the lithosphere. This is broken up into a number of different sections or pieces known as tectonic plates. Underlying the lithosphere is the asthenosphere made up of the softer mantle rocks that behave as a viscous fluid (like an extremely thick treacle). Heat within the earth causes the asthenosphere to convect. This movement causes the overlying lithosphere to move as well. Also where mantle material rises to shallower depths it undergoes a process known as decompression melting. This causes the formation of magma which rises to Earth's surface. This hot (and therefore lower density) material forms a raised area in the Earth's crust known as a mid-ocean-ridge. Gravity acts to try and pull the buoyant hot new crust back down and this force is transferred horizontally through the crust in a process known as "Ridge Push". As the material cools and travels away from the mid-ocean -ridge it sinks slightly back down due to it's increased density and so lower buoyancy. Ultimately this dense oceanic crust may meet a tectonic plate composed of continental crust which has a lower density and is more buoyant than the oceanic crust. Because of this the denser oceanic crust is forced down below the continental crust. This process is known as subduction. The force of gravity acting on the subducting slab is transferred into the rest of the slab acting to pull it towards the subduction zone. This process is known as "slab pull".
Which theory of the plate movement relies on the weight of the sub ducting crust?
The theory that relies on the weight of the subducting crust is known as slab pull. This mechanism suggests that the denser oceanic crust sinks into the mantle at convergent plate boundaries, pulling the rest of the tectonic plate along with it. The gravitational force acting on the subducting slab contributes significantly to the movement of tectonic plates. Slab pull is considered one of the primary driving forces of plate tectonics, along with ridge push and mantle convection.
Are earthquakes caused by slab pull?
Yes, slab pull is one of the mechanisms that can cause earthquakes. It occurs when a tectonic plate's denser oceanic crust subducts beneath another plate, leading to the release of stress accumulated along faults in the Earth's crust. As the subducting slab descends, it can trigger seismic activity both at the subduction zone and along surrounding fault lines. Thus, while not the sole cause, slab pull contributes to the seismic events associated with tectonic activity.
