Why is plate tectonic theory a unifying theory of geology and how does it fit into a systems approach to the study of Earth?
What will be an ideal response?
Answer: Plate tectonic theory provides a unifying explanation for many geologic features and events by relating many seemingly unrelated phenomena and providing a framework for interpreting earth's composition, structure, and internal processes. It fits into a systems approach for the study of Earth because it shows how the continents and ocean basins are part of a lithosphere atmosphere hydrosphere system evolved along with Earth' s interior.
