Discuss how the changes in shape and sizes of continents and ocean basins of the planet take place due to tectonic movements of the crustal masses.
The shapes and sizes of Earth's continents and ocean basins are in a constant state of slow, geological flux, driven by the movement of the planet's lithospheric plates. This process, known as plate tectonics, involves the interaction of these crustal masses at their boundaries, leading to the creation, destruction, and reshaping of the Earth's surface.
Through these continuous interactions, continents drift, oceans expand and shrink, and the world map is perpetually redrawn.
