How do the continents positions change over time?

The positions of continents change over time due to the movement of tectonic plates. This movement is caused by the process of plate tectonics, where the plates that make up the Earth's crust shift and drift on the semi-fluid asthenosphere underneath. This movement can lead to the continents moving closer together (convergence), farther apart (divergence), or sliding past each other (transform) over millions of years.
