Which of the following is a defining characteristic of slab pull?
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.
Which of the following are characteristics of slab pull quizlet?
The following are characteristics of slab pull: Subducting plates move faster than non-subducting plates. Gravity is a major force in slab pull. Subducting oceanic lithosphere is denser than asthenosphere.
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.
What type of plate boundary is created by slab pull?
convergent boundaries The mechanism of slab pull occurs at convergent boundaries. These boundaries exist between two tectonic plates that are moving toward each other and colliding. Many of these boundaries exist between colliding oceanic crust with continental crust.
How do you define a slab pull?
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. Introduction. The history of the development of plate tectonics is centrally tied to the question of what drives plate motions.
What happens during slab pull?
"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.

What is a divergent boundary?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.
What is the effect of ridge push?
Ridge push is the result of gravitational forces acting on the young, raised oceanic lithosphere around mid-ocean ridges, causing it to slide down the similarly raised but weaker asthenosphere and push on lithospheric material farther from the ridges.
Which type of boundary does ridge push occur?
divergent boundary The ridge-push force is created by tectonic plates moving away from a divergent boundary due to their higher elevation than the surrounding ocean floor.
What is slab pull force?
slab pull: the force due to the weight of the cold, dense sinking tectonic plate. ridge push: the force due to the buoyancy of the hot mantle rising to the surface beneath the ridge. viscous drag: the force opposing motion of the plate and slab past the viscous mantle underneath or on the side.
Which of the following is not a characteristic of a mineral?
(d) Their distribution is uneven. Answer: The correct answer is option (C) – They are inexhaustible. Minerals occur in different types of rocks.
What are 3 characteristics of sedimentary rocks?
Sedimentary Rock Textures
- Grain Characteristics. The diameter or width of a clastic sediment grain determines its grain size. …
- Rounding. Clastic sediment grains can be round, angular, or in-between (subangular or subrounded). …
- Sorting. …
- Other Aspects of Texture.
What are the characteristics of divergent boundaries?
Divergent plate boundaries are characterized by shallow earthquakes, volcanic eruptions, a high topographic ridge, and very young lithosphere.
What is convergent boundary?
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
What is ridge pull slab pull?
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. Introduction. The history of the development of plate tectonics is centrally tied to the question of what drives plate motions.
What causes Slab Pull?
As a crustal plate moves further from an oceanic ridge, it cools and becomes increasingly dense. This causes it to sink beneath the continental crust in a subduction zone.
What happens during Slab Pull?
"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.
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 are sedimentary characteristics?
Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth's surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers.
What are the characteristics of convergent boundaries?
The characteristics that describe convergent boundaries are subduction, where one plate sinks under another, and collision, where two plates crash together. This creates features like volcanoes, mountains, and more.
Which characteristics describe divergent boundaries quizlet?
Divergent boundaries form mid-ocean ridges. Divergent boundaries are found on land or undersea. Divergent boundaries form volcanoes. Magma flows from cracks in the crust at divergent boundaries.
Which of the following characterizes a convergent plate boundary?
The characteristics that describe convergent boundaries are subduction, where one plate sinks under another, and collision, where two plates crash together.
Which geologic feature is formed in the divergent plate boundary?
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
Which of the following is not characteristic of mineral?
(d) Their distribution is uneven. Answer: The correct answer is option (C) – They are inexhaustible. Minerals occur in different types of rocks.
Which is not a characteristic of minerals?
minerals cannot be in liquid or gaseous state. They exist only in solid state.
