What is the most likely cause of tectonic plate movement?
The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement.
Which tectonic plate moves the most?
Rates of motion These average rates of plate separations can range widely. The Arctic Ridge has the slowest rate (less than 2.5 cm/yr), and the East Pacific Rise near Easter Island, in the South Pacific about 3,400 km west of Chile, has the fastest rate (more than 15 cm/yr).
What are the 3 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 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.
What is the cause of tectonic plate motion 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 are the two main factors in the movement of plate tectonic plates?
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.

This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.
What is the movement of tectonic plates?
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 the two main factors in the movement of tectonic plates?
Heat and gravity are fundamental to the process 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.
What drives the motion of the continental plates on Earth quizlet?
Earth's lithosphere is broken up into plates that float on the underlying mantle. The tops of the mantle's convection cells drag the bottoms of the plates, making them move. This movement causes spreading in some places and subduction in others.
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.
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.
What process most likely drives plate tectonics quizlet?
The driving force behind plate tectonics is mantle convection.

How do Earth’s plates move quizlet?
States that Earth's plates move slowly in various directions and that Earth's land masses have changed position over time because of they are part of plates that are slowly moving. Why do Earth's plates move? Because churning of hot rock creates a current that causes the plates to move.
How does tectonic plates move?
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 provides the force that moves the tectonic plates quizlet?
Convection currents in the mantle produce a force that causes motion called basal drag. Convection currents in the asthenosphere circulate and drag the lithosphere.

What causes the movement of the plates quizlet?
The correct answer is A. According to the scientists, the movement of the Earth's plates is caused by the convection currents produced from the mantle.
What is the mechanism that drives tectonic plate movement?
The motion of tectonic plates is driven by convection in the mantle. In simple terms, convection is the idea that dense, cold things sink, and buoyant, warm things rise. In the earth the cold sinking things are slabs (subducting plates) and the warm things are plumes, or just rising material from deeper in the mantle.
Which process must occur in the mantle to make the plates move?
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 type of force causes these movements in the plates?
According to the scientists, the movement of the Earth's plates is caused by the convection currents produced from the mantle.

What causes tectonic plates to move physics?
The driving force behind plate tectonics is convection in the mantle. Hot material near the Earth's core rises, and colder mantle rock sinks. "It's kind of like a pot boiling on a stove," Van der Elst said.
Which describes the motion of the plates?
The motion of a plate can be described by a rotation about a virtual axis that passes through the center of the sphere (Euler's theorem). In terms of the Earth, this implies that a single angular velocity vector originating at the center of the globe can describe the motion of a plate.
What force causes the tectonic plates to move around?
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.
What is the main force that causes tectonic plate movement quizlet?
According to the geologists, the movement of the Earth's plates is caused by the convection currents produced by the mantle. There is a presence of the differences in the temperature, changes in the density, and the presence of gravity in the mantle, particularly in the asthenosphere.
