Tectonic plates are segments of the Earth's lithosphere, the hard rocky outer shell composed of the crust and the uppermost mantle. This shell is divided by lines of faults, ridges of plate creation, and zones of plate destruction. All in all, there are roughly 30 tectonic plates which cover the entire surface of the planet. Plates can be composed of oceanic crust, continental crust, or a combination of both.
Plate movements occur because the layer of Earth directly below the lithosphere, the asthenosphere, is hot enough, and under enough lithostatic pressure to prevent its melting, that it can deform without fracture. And although convection of heat does play a role in the movement of lithospheric plates, the convection currents themselves may be caused by gravity, which induces the sinking of older dense slabs of oceanic crust at subduction zones (a process known as 'slab pull').
The energy driving all of these processes is heat from the interior of the Earth derived from radioactive decay and residual heat from Earth's formation, and gravity which results in slab pull and push.
Plate tectonics are what each continent is on. They move and are continuing to move today. It has to do with the earth's shape because the plate tectonics move the continents around.
A theory that says the lithosphere is divided into plates that move around on top of the asthenosphere is called '' plate tectonics''
Plate tectonics are the effects on continental and oceanic plates as they move and collide. Example :"Geologists study plate tectonics to find future stress points and earthquake zones."
No, plate tectonics refers to the theory that Earth's outer shell is divided into several plates that move and interact with each other. These plates are not flat but constantly shifting and changing due to the forces beneath the Earth's surface.
The huge sections of the Earth's crust that move are called tectonic plates. These plates float on the semi-fluid layer beneath them, known as the asthenosphere, and their movements contribute to processes like earthquakes, volcanic activity, and mountain formation.

The theory that states that plates move around on the asthenosphere is called plate tectonics. This theory explains the movement of the Earth's lithosphere into different plates and their interactions at plate boundaries due to the convective currents in the asthenosphere beneath them.
