The theory of continental drift, proposed by Alfred Wegener in the early 20th century, was initially rejected because he couldn't provide a mechanism to explain how the continents moved. It wasn't until the 1960s, with advancements in plate tectonics and paleomagnetism, that scientists were able to provide evidence supporting the movement of continents.

What hypothesis by Alfred wegener explains why continents seem to fit togethere?
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a single supercontinent called Pangaea. Over time, the supercontinent broke apart and the continents drifted to their current positions, explaining why they seem to fit together like pieces of a puzzle.
Why do the coastlines of the continents fit together like puzzle pieces?
The continents fit together like puzzle pieces because they were once part of a supercontinent called Pangaea, which broke apart over millions of years due to the movement of tectonic plates. This phenomenon, known as continental drift, explains the similarities in the coastlines of different continents.
Why do the continents fit together like pieces of a puzzle?
The theory of plate tectonics explains that the continents were once part of a supercontinent called Pangaea, which gradually broke apart and drifted to their current positions. The continents fit together like puzzle pieces because they share similar rock formations and fossils, indicating that they were once connected.
Which two continents did Alfred Wagner think look like they fit together puzzle pieces?
Alfred Wegener proposed that the continents of South America and Africa looked like they could fit together like puzzle pieces to form a single landmass called Pangaea.
What are three pieces of evidence that the continents were once one large landmass?
Continents fit together like puzzle pieces - the coastlines of continents such as South America and Africa seem to fit together like pieces of a puzzle. Fossil evidence - similar fossils of plants and animals found on continents that are now far apart suggest they were once connected. Rock formations and mountain ranges - similar geological features and rock formations found on continents that are now separated indicate they were once part of the same landmass.

Why do you think the continents do not fit together exactly?
Continents do not fit together perfectly, for the same reason a cookie won't if you were to break it violently. ...Some of the pieces that would otherwise cause a perfect fit falls off from the larger pieces as small/large crumbs. Therefore, since it was a powerful force that caused continents to drift, some of the pieces connected to the landmass had most likely fallen or remains adrift as an island or other type of landmass.

What two continents fit together like puzzle pieces?
South America and Africa fit together like puzzle pieces due to the complementary shapes of their coastlines. This observation contributed to the development of the theory of plate tectonics, with the concept of these continents once being part of the supercontinent Pangaea millions of years ago.
Do the continents fit together like the pieces of a puzzle?
Yes, the continents do appear to fit together like pieces of a puzzle. This concept is known as continental drift, where the Earth's landmasses were once joined together in a supercontinent called Pangaea and have since moved apart to their current positions over millions of years.
Why dont the continents fit together perfectly?
Erosion. Back when Pangaea existed, all of the continents fit perfectly together. As they hit each other, they broke off pieces of land and eventually broke apart.
