Plate tectonics is a scientific theory describing the large-scale motion of 7 large
plates and the ..... driving forces were generally acting vertically and caused only
local horizontal movements (t...
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...
The boundary between two plates can be a divergent boundary, a convergent
boundary or a ... The ultimate cause of plate tectonics is the cooling of the Earth.

"The emergence of plate tectonics is arguably Earth's defining moment," they
write. ... The process likely began about 4 billion years ago, and caused complete
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
Tectonic plates move because they are floating on top of the liquid mantle. The
mantle itself ... Why are the convection cells that cause tectonic plate movements
so large? What are the major tectonic plates? How do geologists think the
