Continents are moving across the Earth's Surface under the Continental drift One continent is moving significantly more slowly than the others because of plate tectonics.
Continental Drift
Continental breakup typically starts with the thinning of the lithosphere under a continent, leading to the formation of rift zones. Magma rises to the surface, creating new crust and causing the continent to split into separate landmasses. Over time, these landmasses continue to drift apart due to the movement of tectonic plates.
The continental shelf is located around the edges of the continent where the land drops off into the ocean. It is not necessarily the point where the shore meets the water but the point where the ground drops suddenly and steeply into the ocean depths.
Wegener's theory that the continents slowly moved over Earth's surface became known as the theory of continental drift.
The crust that forms the continents is called continental crust. It is thicker and less dense than oceanic crust, composed mainly of granite rock. Continental crust is what makes up the landmasses on Earth's surface.
A continent is what floats on top of the plate. There are continental and oceanic plates. The continents float on the continental plate and the ocean sits on the oceanic plate. But there are also plates that carry both continents and oceans. The plates are what causes continental drift. So basically plates are what carry the continents and oceans.
The idea that continents move slowly across the earth's surface is called the continental drift.

Continents make up about 29% of the Earth's surface.

Jupiter doesn't have continents, the surface is all made of gas.
Pangaea was a supercontinent that existed around 300 million years ago and is no longer intact. Currently, there is no single continent that consists of all the continents; instead, the continents are distributed across the Earth's surface.
Continental drift, driven by the movement of tectonic plates beneath Earth's surface, causes continents to slowly shift positions over millions of years. The plates are carried by underlying convection currents in the mantle, leading to the movement of the continents on the Earth's surface. This process has shaped the Earth's geology and continues to influence the planet's landmasses.

A continental shift refers to the movement of continents on the Earth's surface due to plate tectonics. This movement is very slow, occurring over millions of years, and can result in changes to the configuration of the continents and the ocean basins. Examples of continental shifts include the breakup of Pangaea into the continents we see today.
