The continental drift theory
The theory that continents have moved slowly over time to their current locations is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics, which explains the movement of Earth's lithosphere through the interaction of tectonic plates.
The fit of the coastlines of different continents, the distribution of similar fossils across continents, and the presence of similar rock formations on different continents led early mapmakers to speculate that continents may have moved over time. This gave rise to the theory of continental drift, which was later developed into the theory of plate tectonics.
Wegener proposed the theory of continental drift because he noticed how coastlines of continents seemed to fit together like pieces of a puzzle. He also observed similarities in rock formations, fossils, and climate across continents that suggested they were once connected. These observations led him to suggest that the continents had moved over time.
Wagner proposed the theory of continental drift, suggesting that the continents were once connected in a supercontinent called Pangaea and have since drifted apart. He believed that the continents moved through the Earth's crust, driven by forces such as convection currents in the mantle.
Scientists believe that North America drifted toward the northwest. Eurasia turned 200 clockwise as it moved northward. Africa and South America broke apart, forming the Atlantic Ocean. Africa turned counterclockwise and moved eastward, while South America moved westward. India separated from Antarctica and Africa,and then moved northeastward. Then India collided with Asia. Australia, once joined to Antarctica,broke off and drifted eastward. Since the continents are still drifting apart, their position will be different millions of years from now.

Continental drift theory
Wegener's theory that the continents slowly moved over Earth's surface became known as the theory of continental drift.
The hypothesis that continents have moved is called continental drift. This theory suggests that Earth's continents were once joined in a single supercontinent called Pangaea and have since moved apart to their current positions.

The theory proposing that continents slowly moved into their current locations is called "plate tectonics." This theory suggests that Earth's outer shell is divided into several plates that glide over the mantle, causing the continents to shift over time.
The hypothesis that states that continents slowly moved to their present-day positions on Earth is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century, suggesting that continents were once part of a single supercontinent called Pangaea and have since drifted apart.

The hypothesis that states continents slowly moved to their present positions on Earth is known as the theory of plate tectonics. It suggests that Earth's lithosphere is divided into several large, rigid plates that move and interact with each other over time. These movements explain various geological phenomena, such as earthquakes, volcanoes, and mountain formation.
