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 ...
Plate tectonics is primarily caused by Earth's cooling mechanism, which
generates convection currents in the planet's mantle that trigger slow but constant
In this lesson, we explore the causes of plate movement, including thermal
convection, ridge push and slab pull. Students will learn how these...

<sup>1</sup> They say a watched pot never boils. But do you know what happens when a pot

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
The theory of plate tectonics and continental drift were proposed at the beginning
