What is one outcome of erosion in tectonically active regions?

• A. Creation of new ocean floors
• B. Formation of sedimentary rocks
• C. Increased volcanic activity
• D. Decrease in mineral resources

Answer: (B)

Erosion in tectonically active regions leads to the formation of sedimentary rocks through a series of geological processes. When tectonic activities occur, they often lift and uplift the Earth's crust, exposing rocks to the surface. These rocks are then subject to weathering and erosion, which break them down into smaller particles. These particles, transported by wind, water, or ice, can accumulate in various environments, such as riverbeds, lakes, or ocean floors. Over time, the accumulation of these sediments becomes compacted and consolidated to form sedimentary rocks. This process is a key aspect of the rock cycle and demonstrates how tectonic forces can initiate and shape the formation of sedimentary structures, contributing to the diversity of the Earth's geology. In this context, the other outcomes listed do not directly relate to the effects of erosion in tectonically active regions in the same way. For instance, creation of new ocean floors relates to divergent tectonic activity rather than erosion, increased volcanic activity pertains to magma movement and not erosion, and decrease in mineral resources does not capture the transformative process that occurs through erosion and sedimentation.
