Unveiling Earth’s Puzzle: Why Are All the Continents Gathered on One Side?

When we look at a world map, it seems like land is spread out evenly. But that’s not entirely true. If you angle a globe towards the Pacific Ocean, you might just see a vast expanse of water. On the flip side, continents like Africa, Europe, and Asia crowd together. So, why do the continents seem clustered?

The answer lies in Pangea, a supercontinent that existed hundreds of millions of years ago. Today, the continents are still slowly drifting apart, mainly due to tectonic activity. The Atlantic Ocean is expanding, pushing the Americas away from Europe and Africa. Yet, they aren’t spreading equally, and they may never do so.

Every 300 to 500 million years, the continents come together to form supercontinents again. For it to count as a supercontinent, at least 75% of the Earth’s land must be connected. Even though Europe, Asia, and Africa are connected, they only cover about 57% of the Earth’s surface.

Pangea was the last known supercontinent, thriving from about 336 million years ago until 175 million years ago. The breakup of Pangea is a fascinating topic, particularly when you notice how the coastlines of South America and Africa fit together like puzzle pieces.

Before Pangea, other landmasses like Gondwana existed, although they aren’t as widely known. The movement of the tectonic plates causes continents to drift apart or come together over millions of years. So, after they cluster, they eventually break apart again.

Looking ahead, in the coming millions of years, we can expect more separation. Eurasia is moving east, while the Americas drift west. Eventually, we may witness the formation of another supercontinent.

For now, if you want to see how our planet looks like a blue marble, just picture it from orbit over the South Pacific, where the vast ocean seems to dominate. Earth is a beautiful sphere of deep blue with patches of land scattered throughout.

An interesting note from geologists suggests that the movements of these landmasses could affect everything from climate patterns to ocean currents. So, while continents may feel fixed to us, they’re actually on a long and slow journey.
