Which geological features are more likely to occur along plate boundaries?

• A. Sedimentary Rocks
• B. Earthquakes and Volcanoes
• C. Metamorphic Rocks
• D. Groundwater Storage

Answer: (B)

When tectonic plates interact at their edges, energy from their movement is released as earthquakes, and melting rocks near those boundaries provides magma that can reach the surface as volcanoes. This combination—earthquakes from stress along faults and volcanic activity from rising magma—is most expected at plate boundaries, where plates slide past, collide, or pull apart. Real-world examples include earthquakes along major faults like the San Andreas and the volcanic activity around the Pacific Ring of Fire, which sits along many plate boundaries. Sedimentary rocks are formed from deposited material and aren’t tied to boundary regions specifically; metamorphic rocks arise from heat and pressure but aren’t the defining feature of plate boundaries everywhere; groundwater storage deals with water movement in and around rocks, not the dynamic tectonic activity that characterizes plate edges.
