continental drift
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.
The theory of plate tectonics proposes that Earth's lithosphere, which consists of large plates that float on the semi-fluid asthenosphere, has moved and shifted over time. This movement has caused continents to slowly drift to their current positions on Earth.
The hypothesis that states the continents once formed a single landmass, broke up, and drifted to their present locations is known as the theory of plate tectonics. This theory explains the movement of Earth's lithosphere plates and the distribution of continents and oceans on the planet's surface. It is supported by evidence from fossil records, rock formations, and the matching coastlines of continents like South America and Africa.
The hypothesis that states the continents were once joined together in a single supercontinent is called "Pangaea." This theory suggests that due to the movement of tectonic plates, Pangaea eventually broke apart over millions of years to form the continents as we know them today.
Continental drift.
Based on an apparent fit between Africa and South America Wegener hypothesized that at one time all continents were joined together in a "subcontinent" called Pangaea. The super-continent eventually broke into the smaller continental. which then "drifted" towards their present positions. Wegener supported his hypothesis by using circumstantial evidence, similar to the way that a detective would collect. evidence to solve a crime. There are four lines of evidence:
The hypothesis that all continents were created by the break-up of Pangaea is called the theory of plate tectonics. This theory states that the Earth's lithosphere is divided into large plates that move and interact with each other, leading to the formation and movement of continents.
