Final answer:
Yes, sand erosion supports the theory of plate tectonics by demonstrating the movement of lithospheric plates on Earth's surface.
Step-by-step explanation:
Yes, sand erosion does support the theory of plate tectonics. The movement of sand through erosion can help explain the movement of lithospheric plates on Earth's surface. Sand erosion occurs as a result of weathering and mechanical processes, such as wind, water, and glaciers. These forces reshape landforms, including mountains, valleys, and coastlines. In the context of plate tectonics, the erosion of sand can be a direct consequence of movements and interactions between tectonic plates.
