Catch my Drift?

Have you ever wondered why Earth's continents look like they should fit together, almost like a puzzle? Thanks to Geologist Alfred Wegener's, we now know that each continent is embedded in one of  the earth's tectonic plates, and that these plates are constantly moving. We call these broken up plates the lithosphere. According to Keller and DeVecchio, (Natural Hazards, 33-34), the lithospheric plates move over another layer called the asthenosphere.

In a Divergent boundary, two plates are moving away
from each other, while hot mantle is rising up from the center
forming a rift. (Keller and DeVecchio)

Great Britain is located on the Eurasian plate, yet it is not close to the division of the plates. To its right lies a Divergent boundary line (pictured right), which according to the British Geological Survey is responsible for creating more lithosphere as plates move away from each other.

However,  because it does rest on some fault lines, Great Britain experiences a few minor earthquakes each year. The earthquakes are caused by stress in the crust below Britain, which is caused by the shifting of the Eurasian plate.
