Answer:
The best fit between South America and Africa is observed when using the theory of plate tectonics. This theory explains that the continents were once part of a larger supercontinent called Pangaea, which began breaking apart around 175 million years ago. Over millions of years, the continents drifted to their current positions. The fit between South America's east coast and Africa's west coast is particularly noticeable, supporting the theory of continental drift and plate tectonics.
Step-by-step explanation:
you could consider Pangaea was a supercontinent that existed around 335 to 175 million years ago during the late Paleozoic and early Mesozoic eras. The term "Pangaea" comes from the ancient Greek words "pan," meaning all, and "gaea," meaning Earth. It refers to the idea that all the Earth's continents were once joined together as a single landmass.
The concept of Pangaea is a key component of the theory of plate tectonics, which explains the movement of the Earth's lithospheric plates over geological time. According to this theory, Pangaea began breaking apart due to the movement of these plates. As Pangaea split, the pieces drifted to their current positions on the planet's surface, forming the continents as we know them today.
The breakup of Pangaea led to the formation of the Atlantic Ocean as new oceanic crust formed between the separating continents. Over millions of years, the continents continued to move, driven by the convective currents in the Earth's mantle. This movement continues to shape the Earth's surface, leading to the geological features we see today, such as mountain ranges, ocean basins, and earthquakes
