But without a mechanism to explain how the continents could actually "drift," most geologists dismissed his ideas.

The next step is continental drift, sea-floor spreading, ocean formation – and hello, Atlantic Ocean.

In fact, the Atlantic is still opening, generating new plate material in the middle of the ocean and making the flight from New York to London a few inches longer each year. tectonic plate sinks beneath another, a process geologists call subduction.

That in turn acts on the lithosphere, changing the direction plates move.

This is how, for instance, South America broke away from Africa.

We now know there are 15 major plates that cover the planet's surface, moving at around the speed at which our fingernails grow.

Based on radiometric dating of rocks, we know that no ocean is more than 200 million years old, though our continents are much older.

He noted that the Earth's current landmasses could fit together like a jigsaw puzzle.

After analyzing fossil records that showed similar species once lived in now geographically remote locations, meteorologist Wegener proposed that the continents had once been fused.

From this evidence, Wilson showed that the Atlantic Ocean had opened, closed and re-opened again, taking parts of its neighboring landmasses with it.

And there it was: proof our planet's continents were not stationary.

Off the Pacific Northwest coast of the United States, the ocean is slipping under the continent and into the mantle below the lithosphere, creating in slow motion Mount St Helens and the Cascade mountain range.
