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.
Erosion over time.
Two reasons the continents didn't fit perfectly together while they were Pangaea are the effects of erosion and sea level changes. Over time, erosion of the coastlines and movement of tectonic plates caused the shapes of the continents to change. Sea level changes due to factors like glaciation also altered the coastlines and made the fit less perfect.
They dont. Go home,
Most continents fit together the best along their coastlines, such as the east coast of South America aligning with the west coast of Africa. This alignment is evidence of the theory of plate tectonics, where continents were once joined together in a single landmass called Pangaea.
The continents that were proposed to have once fit together are called Pangaea. This supercontinent existed around 300 million years ago before breaking apart into the continents we know today.
If put together, they would fit perfectly into one huge super continent like a puzzle.
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in the early 20th century based on the idea that the Earth's continents appeared to fit together like pieces of a jigsaw puzzle. This laid the foundation for the development of the theory of plate tectonics.
They would fit roughly together but not perfectly due to years and years of erosion. As evident as Africa and So. America are that they were once joined. Erosion does not work. Even with that they will not fit. Try it with cut outs. But shrink the size of the earths sphere to about 1/2 its size today and they fit perfect.
The present shape of the continents does not fit perfectly into the shape of a supercontinent because the Earth's tectonic plates are constantly moving. These movements are driven by processes like plate tectonics and convection currents in the mantle, causing the continents to drift apart, collide, and rearrange over millions of years. This results in the continents having different shapes and positions compared to when they were part of a single supercontinent like Pangaea.
every one should because the continents did once fit together
pangea is a super-continent formed a long time ago when all of the seven continents came together. the largest amount of evidence scientists have is that all of the continents fit almost perfectly together, like a puzzle.
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.
