How does plate tectonics influence sedimentary rock formation?

• A. It prevents any erosion from occurring
• B. It creates basins that enhance sediment deposition
• C. It solely creates igneous rocks
• D. It alters the chemical composition of all rocks

Answer: (B)

Plate tectonics plays a significant role in shaping the Earth's surface and influencing sedimentary rock formation through processes such as the creation of basins. These tectonic activities can lead to the subsidence of land and the development of low-lying areas where sediment can accumulate over time. As geological features such as mountains form due to tectonic uplift, adjacent areas can become basins that collect sediments from weathering and erosion of those uplifted regions. This accumulation of sediments eventually compacts and cements over geological time, leading to the formation of sedimentary rocks. For example, when tectonic plates converge, they may create mountain ranges that force sediment-laden rivers into depressions, allowing for significant sediment deposition. Conversely, while other features related to plate tectonics, such as volcanic activity and metamorphism, contribute to the rock cycle, they do not directly create conditions favorable for sedimentary rock formation as effectively as the development of basins does. Hence, the correct choice emphasizes the influence of plate tectonics in enhancing sediment deposition through basin formation.
