Why don't the present shapes of the continental fit perfectly into a supercontinent?

Changes in sea level, erosion, and deposition of sediment call all change the shapes of Coastlines. What fit together even better than the continents themselves are the continental shelves. These areas were once dry land but dropped below sea level as Pangaea broke up. Even these can become somewhat distorted by tectonic forces.

Why don't the present shapes of the continents fit perfectly into a supercontinent?
One reason is because the coastlines of land masses change over time. If you map the edges of the continental shelves, the fit is much better.
Why don't the present shapes of the continents fit perfectly into a super continent?
As the continents moved further apart, natural erosion of the Coastlines removed and added to the basic shape over billions of years. Much of the evidence relates to the similarities of plants and animals found on now separate continents. Geological evidence points to Antarctica was once further north and had a tropical climate!
What are the positive shapes in the Marizy Sainte-Genevieve painting?
- What are positive shapes the shapes of artist's canvases the main shape in a painting the automatic shapes created for backgrounds.
How and why have the shapes of the continents changed over millions of years?
By way of a geological process call "Plate Tectonics" (aka continental drift). Continents sit on 8 major plates which are denser than the level below them and move 50-100 mm annually.

What could possibly cause present day shape of the continents not fit perfectly into a large supercontinent?
Sea level changes, erosion, sedimentation, and uplift and subsidence of the surface can change the shapes of costlines. It has been dound that the present day continental shelves acutally fit together better than the coastlines. This makes sense, as when Pangaea rifted apart, the land immediately around the rifts would have dropped below sea level.
What are shapes that fit together with no gaps called?
Shapes that fit perfectly together are called a tessellation.
Why do Continental glaciers smooth the landscape?
Continental glaciers smooth the landscape because continental glaciers are flat unlike the rough shapes of Alpine glaciers.
