Plate tectonics is a scientific theory describing the large-scale motion of Earth's
lithosphere. ..... driving forces were generally acting vertically and caused only
local horizontal movements ...
In this lesson, we explore the causes of plate movement, including thermal
convection, ridge push and slab pull. Students will learn how these...
The three primary causes for tectonic plate movement are the convection of
material in the mantle, gravity and the rotation of the planet. These forces cause

Earth's core that causes molten rock in the mantle layer to move.
May 5, 1999 ... Yet violent earthquakes related to plate tectonics have caused terrible
catastrophes -- such as the magnitude-7.7 earthquake that struck the ...
Tectonic plates move because they are floating on top of the liquid mantle. ... Why
are the convection cells that cause tectonic plate movements so large?
Mar 21, 2016 ... Plate tectonics is the theory that Earth's outer shell is divided into several plates
that glide over the mantle.

Oct 29, 2015 ... The Earth is divided into an inner core, made mostly of iron, and an outer part,

This is called continental drift colloquially, and plate tectonics (see also this ... the
plates of the lithosphere much as convection in a pan of boiling water causes a ...
The sinking oceanic lithosphere drags the rest of the tectonic plate: this is the
main cause of plate motion. Oceanic lithosphere is therefore pulled apart in
