What are the 3 drivers of plate tectonics?
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.
What are the 3 causes of the movement of plate tectonics?
Scientists have theorized three mechanisms that cause plate movement on Earth. These three mechanisms are thermal convection, ridge push, and slab pull.
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.
What is the driving force of plate tectonics quizlet?
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 plates to move?
The forces that drive Plate Tectonics include: Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges) Slab pull (gravitational force in subduction zones)
What drives the motion of the 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.
What is the driver of plate tectonics quizlet?
The driving force behind plate tectonics is mantle convection.
Which processes are responsible for driving plate tectonics quizlet?
Convection currents in the Earth's mantle are responsible for the movement of tectonic plates. As shown in the diagram, heat from the Earth's core is the driving force that moves magma in a circular motion called "cells."
What is considered the most important driving factor for plate tectonics?
Heat is continuously flowing outward from Earth's interior, and the transfer of heat from the core to the mantle causes convection in the mantle (Figure 1.7). This convection is the primary driving force for the movement of tectonic plates.
What is 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.
What force drives the movement of tectonic plates quizlet?
The driving force behind plate tectonics is mantle convection.
What facilitates the movement of tectonic plates?
Summary: A small amount of molten rock located under tectonic plates encourages them to move.
What force moves the continents?
1 Answer. The theory of plate tectonics suggests that it is convection currents in the mantle of the earth that causes the movement of the continental plates.
What is the driving force for plate tectonics quizlet?
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 most of the plate movement?
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 causes tectonic plates to move quizlet?
convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.
What forces plates to move?
The gravity-controlled sinking of a cold, denser oceanic slab into the subduction zone, dragging the rest of the plate along with it, is considered to be the driving force of plate tectonics.
How does gravity cause plates to move?
In the current understanding of plate motion the movement is driven by the weight of cold, older, dense plate material sinking into the mantle at deep ocean trenches and pulling the rest of the plate slab with them as gravity causes them to slide downwards.
What basically drives the forces that result in a fault *?
Fault systems evolve and change over time—driven by plate tectonic forces associated mantle convection influencing the rigid lithosphere. Fault systems are often associated with volcanic regions.
How are tectonic plates formed?
Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature1. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says.
What causes tectonic plates to move GCSE?
One explanation for the movement of the Earth's crustal plates is believed to be convection currents which occur in the semi-molten mantle. These convection currents are created by heat from within the earth – much of which is generated by radioactive decay in the core.
How does convection causes tectonic plates to move quizlet?
Theory that the Earth's crust is divided into tectonic plates which move around due to convection currents in the mantle. The movement caused within a fluid by hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity. Plates pull apart and magma rises up.
How are the tectonic plates moving?
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
What is the forces within the Earth that causes the ground to move?
They are brought about by tectonic forces which originate and operate in the interior of the earth e.g. tensional forces (which operate along horizontal plane moving away from each other), compressional forces (which operate along horizontal plane moving towards each other), shear forces (which move past each other …
What are the forces of the earth?
Forces in the Earth. There are three main forces that drive deformation within the Earth. These forces create stress, and they act to change the shape and/or volume of a material. The following diagrams show the three main types of stress: compressional, tensional, and shear.
What are the two main factors of tectonic plates movement?
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.
Why do tectonic plates move quizlet?
convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.
What causes convection currents and plates to move?
Magma is the molten rock below the crust, in the mantle. 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 tectonic plates are formed?
Starting roughly 4 billion years ago, cooler parts of Earth's crust were pulled downwards into the warmer upper mantle, damaging and weakening the surrounding crust. The process happened again and again, the authors say, until the weak areas formed plate boundaries.
