Which of the following does not provide evidence for plate tectonics?

• A. Radiometric dating of rocks
• B. Distribution of fossils
• C. Current position of modern-day glaciers
• D. Matching coastlines of continents

Answer: (C)

The current position of modern-day glaciers does not provide direct evidence for plate tectonics. Plate tectonics is fundamentally about the movement of the Earth's lithospheric plates and how this movement shapes geological features over time. Evidence for plate tectonics generally comes from geological and fossil records, showing how continents have drifted apart or collided.

While the current position of glaciers can indicate climatic conditions and historical environmental changes, it does not directly relate to the movement of tectonic plates. In contrast, radiometric dating of rocks helps establish the ages of various geological formations, providing insights into the timing of tectonic events. The distribution of fossils supports the theory by showing how species could have once inhabited areas now separated by oceans due to plate drift. The matching coastlines of continents, such as South America and Africa, visually and geologically illustrate how these landmasses were once joined before breaking apart, reinforcing the idea of continental drift as a component of plate tectonics.
