What does slab pull refer to?
Slab Pull: The force exerted by the weight of the subducted slab on the plate it is attached to. Ridge Push: The pressure exerted by the excess height of the mid-ocean ridge.
What is slab pull in geography?
Slab pull occurs where older denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink newer and less dense sections of plate are pulled along behind. Sinking in one place leads to plates moving apart in other places.
What happens during slab pull?
As it cools It becomes denser and slides down away from the ridge. This causes other plates to move away from each other. Slab pull – The denser plate sinks back into the mantle under the influence of gravity. It pulls the rest of the plate along behind it.
What is slab pull quizlet?
Slab pull. The process that results when a dense oceanic plate sinks beneath a more buoyant plate along a subduction zone, pulling the rest of the plate that trails behind it. convection.
Where is slab pull located?
Subduction zones Slab pull occurs when an oceanic plate subducts into the underlying mantle. Subduction zones are just one type of convergent boundary where two tectonic plates are colliding.
Where do slab pull occur?
subduction zone Slab pull occurs at a convergent boundary and subduction zone. The force of the dense oceanic plate subducting under the continental plate and gravitationally being pulled into the mantle results in the rest of the plate being pulled along with it.
What is ridge push and slab pull quizlet?
The process that results when magma rises at a mid-ocean ridge and pushes oceanic plates in two different directions away from the ridge. Slab pull. The process that results when a dense oceanic plate sinks beneath a more buoyant plate along a subduction zone, pulling the rest of the plate that trails behind it.
Which of the following is referring to a ridge push quizlet?
Which of the following is referring to a ridge push? eruption of lavas and solidification of magmas at depth.
Is divergent boundary a slab pull?
In divergent zones, the plates are pulled, and not pushed, apart. The main force driving this plate motion (although there are other lesser forces) is the "slab pull" that arises when plates sink into the mantle under their own weight at subduction zones.
How is slab pull caused?
Slab pull is the pulling force exerted by a cold, dense oceanic plate plunging into the mantle due to its own weight. The theory is that because the oceanic plate is denser than the hotter mantle beneath it, this contrast in density causes the plate to sink into the mantle.
What is a slab pull quizlet?
Slab pull. The process that results when a dense oceanic plate sinks beneath a more buoyant plate along a subduction zone, pulling the rest of the plate that trails behind it. convection.
Where does slab pull occur?
subduction zone Slab pull occurs at a convergent boundary and subduction zone. The force of the dense oceanic plate subducting under the continental plate and gravitationally being pulled into the mantle results in the rest of the plate being pulled along with it.
What is ridge push slab pull?
'Ridge Push' and 'Slab Pull' are thought to be the major forces driving the motion of oceanic plates. Ridge push is caused by the potential energy gradient from the high topography of the ridges. Slab pull is caused by the negative buoyancy of the subducting plate.
How does slab pull effect plate movement?
"slab pull" As lithospheric plates move away from midocean ridges they cool and become denser. They eventually become more dense than the underlying hot mantle. After subducted, cool, dense lithosphere sinks into the mantle under its own weight. This helps to pull the rest of the plate down with it.
Why does slab pull occur?
Slab pull is the pulling force exerted by a cold, dense oceanic plate plunging into the mantle due to its own weight. The theory is that because the oceanic plate is denser than the hotter mantle beneath it, this contrast in density causes the plate to sink into the mantle.
