Timelines
The tectonic plates that make up the Earth's crust have been slowly moving for billions of years. This is the scientific theory of plate tectonics. As a consequence, the Earth's continents have changed dramatically over time.
For the sake of clarity, brevity, or some other reason, certain details or events may not be included in this timeline.
