How does the internal structure of the earth influence the creation of continents oceans and mountain ranges

The internal structure of the earth influences the creation of continents, oceans, and mountain ranges by facilitating the movement of plates. Convection currents within the Earth's mantle constantly churn and move the rocky plates sitting atop. These plates collide (creating mountains), spread apart (creating basins and oceans), and subduct beneath one another (creating continental boundaries).
