How do you notice the shape of west coast Africa and east South America?

The shape of west coast Africa and east South America can be noticed by looking at a map of the world or a globe. The two continents are located on opposite sides of the Atlantic Ocean, and their coastlines have a distinct shape that is often referred to as the "S" shape. This is because the coastlines of both continents curve inwards towards the Atlantic Ocean, creating a large bay that is known as the Gulf of Guinea. The shape of the coastlines is also characterized by the presence of several peninsulas and islands, such as the Iberian Peninsula, the Cape Verde Islands, and the Canary Islands. Additionally, the coastlines of both continents are home to some of the world's largest cities, such as Lagos, Rio de Janeiro, and Buenos Aires.
