Can't claim expertise in the field, but found it interesting, just the same :: shrug ::

The concept of plate tectonics was formulated in the 1960s. According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 100 km (60 miles) thick and overlies a plastic (moldable, partially molten) layer called the asthenosphere.
The lithosphere breaks up into 7 very large continental- and ocean-sized plates,6or7 medium-sized regional plates,several small ones.These plates move relative to each other at rates of 5to10 cm/year,and interact along their boundaries,converge, diverge,slip past one another.
Such events are thought to be responsible for most of Earth’s seismic and volcanic activity.Plate motions cause mountains to rise where plates push together, or converge, and continents to fracture and oceans to form where plates pull apart, or diverge.
Plate tectonics is dealing with the dynamics of Earth’s outer shell—the lithosphere—that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes,volcanoes,earthquakes.
The continents are embedded in the plates and drift passively with them, which over millions of years results in significant changes in Earth’s geography.
As well as the evolution of Earth’s surface and reconstructing its past continents and oceans.

Fascinating....

When I drop butter into water heating up, the little individual "islands" of melted butter float on the surface, twirl around, join, and separate just like plate tectonics, all as the result of the hot water circulating in the pan. It's so obviously similar that I sometimes wonder if something like that is where the plate tectonics theory came from. Then, of course, there's the theory that the plates sometimes move around much faster (practically overnight in geological terms) which explains some of the things they've found that otherwise don't fit neatly into a "gradual" (again, geologically speaking) system like plate tectonics.
