Many have noticed that the continents look somewhat similar, but it is difficult to say what. The northern part tends to be wider than the southern part. Comparing with the divisions found within the convection rolls model, a basic shape of North America be pointed out.
The coast of the Pacific Ocean is obviously more regular than the East Coast. The continent all the same follows this basic shape surprisingly well. This shape resembles the southern part of Africa as shown in another post.
I have a BS degree in geology, BA in anthropology, graduated in Chinese language and as a certified tourist guide. I provide this website about my contribution to answer the greatest question remaining about our Earth. I have analyzed the convection rolls within the Earth's mantle and how they affect the surface. This makes it possible to provide many interesting examples about geology found on my blog.
