Continents shift at about the same rate as your fingernails grow

Continents are the massive bodies of land that make up all of the countries on Earth. They may seem like they are immovable, but they are actually constantly moving at very slow speeds. Continents move at roughly the same speed as our fingernails grow. Moving just millimeters at a time, the original continent made up of all the modern continents, Pangea, took hundreds of millions of years to break apart and form today’s landmasses. Eventually, the continents may crash into one another.
