The major types of plate tectonic boundaries are:
Divergent Plate Boundary: The area where two plates are moving in relatively opposite directions and new crustal material is being created. Examples would be the mid-ocean ridges, and the East African Rift.
Convergent Plate Boundary: The area where two tectonic plates are moving toward each other and one of two things happens; either the more dense plate subjects under the lighter plate and heads toward the mantle, or, if the plates are of similar density, they cause uplift and mountain forming events. Examples would be the oceanic to continental crustal collision creating the Andes Mountains, and the continental to continental crustal collision creating the Himalayan Mountains.
Transform Plate Boundary: The area where two plates are grinding past each other, snapping into place from elastic rebound as they go, causing numerous earthquakes. The San Andreas Fault is an example of a transform plate boundary between the North American and Pacific plates.
The process of seafloor spreading at mid-ocean ridges creates constant plate motion. As magma rises along the ridge and solidifies, it pushes the existing plates apart, leading to continuous movement of the plates. This process is driven by heat from the Earth's core and helps to renew the ocean floor.
tectonic plates
There are multiple tectonic plates that make up Earth's crust, with the number of major plates usually defined as around 7 to 8. These plates are in constant motion due to the process of plate tectonics, leading to various geological activities such as earthquakes and volcanic eruptions.
Convection ridge push and slab pull work together to produce plate motion within the Earth's lithosphere. Ridge push occurs at mid-ocean ridges where newly formed crust pushes older crust away, while slab pull occurs at subduction zones where denser oceanic crust sinks into the mantle, pulling the plate along with it. These forces combined drive the movement of tectonic plates.
The energy driving tectonic plate motion primarily comes from the Earth's internal heat, which generates convection currents in the mantle. These currents transfer heat to the crust, causing the plates to move. Additionally, gravitational forces and the Earth's rotation play a role in the movement of tectonic plates.
The asthenosphere, which is a partially molten layer in the upper mantle, has convection currents that cause tectonic plates to move due to the heat-driven circulation of rock material. These convection currents are responsible for the continuous motion of tectonic plates on the Earth's surface.

Things such as molecules, atoms, planets, stars, and light are in constant motion. Additionally, particles in the atmosphere, ocean currents, and even the Earth's tectonic plates are in constant motion.
The Earth's tectonic plates are in constant motion. This movement is possible because they lay on top of the asthenosphere which is the outer mantle.

Continental drift is the theory that "plates" on the Earth are constantly in motion and have been for millions of years. Tectonic plates are the actual moving plates.

Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.

Additionally, convection currents in the mantle drive the movement of tectonic plates. This convection occurs as molten rock rises and cools, creating a continuous cycle of movement beneath the Earth's surface.
