What Is The Underlying Force That Drives Plate Tectonics??

Heat and gravity are fundamental to the process

The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.Dec 12 2017

What is the underlying force that drives plate tectonics quizlet?

The driving force behind plate tectonics is mantle convection. Also called earthquake waves.

What drives the movement of tectonic plates?

The heat from radioactive processes within the planet’s interior causes the plates to move sometimes toward and sometimes away from each other. This movement is called plate motion or tectonic shift.

Which driving force of plate tectonics is the strongest?

Although subduction is believed to be the strongest force driving plate motions it cannot be the only force since there are plates such as the North American Plate which are moving yet are nowhere being subducted.

Which of the following is considered to be the main driving force of plate tectonics resulting in earthquakes?

Research has shown that the major driving force for most plate movement is slab pull because the plates with more of their edges being subducted are the faster-moving ones. However ridge push is also presented in recent research to be a force that drives the movement of plates.

What type of activity drives plate motion quizlet?

–Convection in the mantle drives plate motion. -The Earth is cooling slowly over time and the heat loss results in convection in the mantle the rise of heat and the sinking of cooler material.

What drives the motion of tectonic plates on Earth quizlet?

Part of the mantle consists of the molten material that circulates in convection currents beneath the earths crust. This process drives plate tectonics. the transfer of thermal energy (heat) from the core by the circulation or movement of Mantle material.

Where are the tectonic plates moving?

The Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (cm) or ~3-4 inches a year. The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean the Mid Atlantic Ridge.

What is the driving force of convection currents?

The heat produced in the interior of the earth is thought to be the driving force behind plate tectonics. That heat creates convections currents that can be observed in volumes of air and liquid is a known fact. There is substantial evidence that heat is produced in the core and mantle of the earth.

Which force is the driving motion of the North American plate?

Many geologists argue that the force of convection is not enough to push enormous lithospheric plates like the North American plate. They suggest instead that gravity is the main driving force: Cold dense oceanic crust sinks at subduction zones pulling the rest of the plate with it.

What is the example of plate tectonics?

Tectonic plates earthquakes and volcanism

A good example are the boundaries of the Pacific Plate where more volcanoes and earthquakes occur than in the rest of the world combined. Because of this it is often called the “Ring of Fire”.

Which of the following processes drives plate tectonics?

The driving force behind plate tectonics is convection in the mantle. Hot material near the Earth’s core rises and colder mantle rock sinks.

What force causes the movement of Earth’s plates quizlet?

According to the scientists the movement of the Earth’s plates is caused by the convection currents produced from the mantle.

What is the main source of energy driving plate tectonics and the Geodynamo?

Although solidification of the inner core with light element partition- ing at the inner core boundary is the thought to be the primary energy source for the geodynamo today the pathway of this energy can be traced backward through the outer core and mantle all the way to the surface where it was first injected into …

How do convection currents drive plate motion?

Convection currents describe the rising spread and sinking of gas liquid or molten material caused by the application of heat. … Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.

How are convection and plate tectonics?

The convection currents move the plates. Where convection currents diverge near the Earth’s crust plates move apart. Where convection currents converge plates move towards each other. The movement of the plates and the activity inside the Earth is called plate tectonics .

What process drives mantle convection quizlet?

What process drives mantle convection? The transfer of thermal energy from Earth’s core toward its surface.

How does energy drive plate tectonics?

Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.

Why does plate tectonics occur quizlet?

Thermal energy generated in the Earth’s core causes the tectonic plates on the Earth’s surface to move. This movement occurs due to convection currents deep in the Earth. … Convection currents in the mantle move the tectonic plates on the Earth’s surface.

In which layer of the Earth does the motion of the convection drive plate movement?

Does mantle convection drive plate tectonics? After the discovery of radioactivity by Marie Curie and Henri Becquerel in 1896 it became clear that the Earth’s interior would be heated by radioactive decay in the mantle and crust. Rock is a poor conductor of heat.

What are three ways that tectonic plates move?

The movement of the plates creates three types of tectonic boundaries: convergent where plates move into one another divergent where plates move apart and transform where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.

What are three causes of plate movement?

Mantle dynamics gravity and Earth’s rotation taken altogether causes the plate movements. However convectional currents are the general thought for the motion.

What is plate tectonics?

A tectonic plate (also called lithospheric plate) is a massive irregularly shaped slab of solid rock generally composed of both continental and oceanic lithosphere. … Like icebergs only the tips of which are visible above water continents have deep “roots” to support their elevations.

What drives the convection current in the Earth’s mantle?

The warmer less dense rock material near the core slowly moves upward. Relatively cooler rock from higher in the mantle slowly sinks toward the mantle. … While the mantle material remains solid the heat and pressure allow convection currents to move the mantle material.

Does drag force resists movement of lithospheric plates?

The drag force operates on almost all parts of a moving lithospheric plate. … However the basal drag force still acts to resist plate motion at the interface between the lithosphere and upper mantle.

Which driving force for plate movement occurs at mid ocean ridges?

Ridge push (also known as gravitational sliding) or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot raised asthenosphere below mid-ocean ridges.

Which type of force occurs at Transform plate boundaries?

Transform faults and divergent boundaries

Although separated only by tens of kilometers this separation between segments of the ridges causes portions of the seafloor to push past each other in opposing directions.

How do plate tectonics work?

The theory of plate tectonics states that the Earth’s solid outer crust the lithosphere is separated into plates that move over the asthenosphere the molten upper portion of the mantle. Oceanic and continental plates come together spread apart and interact at boundaries all over the planet.

What type of tectonic plate is the North American plate?

continental plate

plate is exemplified by the North American Plate which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge. The latter is an enormous submarine mountain chain that extends down the axis of the Atlantic basin passing midway between Africa and North…

What are the 4 types of tectonic plate movement?

What are the major plate tectonic boundaries?

• Divergent: extensional the plates move apart. Spreading ridges basin-range.
• Convergent: compressional plates move toward each other. Includes: Subduction zones and mountain building.
• Transform: shearing plates slide past each other. Strike-slip motion.

Which is the best example of a convergent plate boundary?

Answer: The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.

Which of the following refers to a plate movement due to the plates being pushed apart?

Divergent boundaries. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.
