The outlines of the continents would change drastically if the sea-levels rose or fell. They are the shape they are because of the amount of water on the surface of the earth.
They are also the shape they are because the "land" sits on tectonic plates deep below the surface, and these plates move about - pushing land-masses together.

The continents' shapes are a result of the movement of tectonic plates on Earth's surface over millions of years. This movement, through processes like plate convergence and divergence, has shaped the landmasses we see today. Erosional forces such as wind and water have also contributed to the current shapes of the continents.

How do continents gain their shape?
Continents gain their shape through a combination of tectonic plate movements and erosion processes. Plate tectonics cause continents to drift and collide, leading to the formation of mountain ranges, valleys, and other landforms that shape the continents. Erosion by water, wind, and ice further shapes the continents over time by wearing down and reshaping the land.
Why would the present shape of the continents not fit perfectly into the shape of a supercontinents?
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.
Why do the continents look the way that they do?
The current shape and arrangement of continents is due to the movement of tectonic plates. Over millions of years, the plates have shifted, collided, and pulled apart, leading to the formation of the continents we see today. This process, known as plate tectonics, continues to shape the Earth's surface.
How long ago did modern continents begin to take shape?
Modern continents began to take shape around 200 million years ago during the breakup of the supercontinent Pangaea. This process resulted in the formation of the continents we see today, as they drifted into their current positions.
What do the shape of the continents tell us about their past?
The shape of the continents is evidence of the movements of tectonic plates over millions of years. The continents were once part of a supercontinent called Pangaea, which began to break apart about 200 million years ago. This process, known as plate tectonics, explains why the continents fit together like a puzzle and why their shapes are complementary.
Which suggested to early cartographers that the continents were once joined?
The shape of the continents.
What evidence is there that the continents were joined together at one time?
Evidence supporting the concept of continental drift and the past existence of a supercontinent includes the fit of the continents' coastlines, similarities in rock formations and fossils across currently separated continents, matching mountain ranges on different continents, and the distribution of certain ancient climate-sensitive rock formations like glacial deposits. Additionally, paleomagnetic data from rocks indicate the past movement of continents.
What two continents are similar is shape?
Australia and Antarctica are the two continents that are similar to islands.
Why would the present shape of the continents not fit perfectly into the shape of a supercontinents?
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.
What discipline records the shape and location of continents?
What scientific disciplines records the shapes and locations of continents
Would you use a map or globe to see a continents exact shape?
because it helps you see the shape of the continents. Globe, The curved shape is more like the real world so it is more exact.
What two continents have a similar physical shape?
california
What did mapmakers notice about the shape of the continents?
Mapmakers noticed that the shapes of continents appeared to fit together like pieces of a jigsaw puzzle, suggesting they were once joined together. This observation contributed to the development of the theory of continental drift and later the theory of plate tectonics.
Why do you think our plants continents look the way they do today?
The shape of the continents is mainly due to water erosion.
What is the accurate shape of a globe allows mapmakers to show earths continents and oceans?
size of island ,continents, and body of water.
What Two continents are similar in physical outlined shape?
Africa and South America are similar in physical outline shape. This resemblance is due to the way these continents used to fit together as part of the supercontinent Pangaea.
At the end of mesozoic era did the continents took on their modern shape?
True
