Seafloor spreading helps explain continental drift in the theory of plate tectonics. Fault-block mountains often result from rifting, an indicator of extensional tectonics. The locations of earthquakes provide information on plate tectonics and mantle convection. These volcanoes are associated with the tectonics of Bransfield Rift. The whole peninsula was formed by intense tectonics (faults, overthrusts and regional metamorphism). Marine terraces play an important role in the research on tectonics and earthquakes. This facility hosts interpretive displays on earthquakes, plate tectonics, and a working seismograph. The constant rearrangement of continents by plate tectonics can also shape long-term climate evolution. There is, however, no scientific consensus on the evolution of plate tectonics on Earth. The plate tectonics rock cycle is an evolutionary process. This era is marked by the further development of continental plates and plate tectonics. Pangaea's formation is now commonly explained in terms of plate tectonics. This is called a divergent plate tectonics boundary. Calcium cycling provides a link between tectonics, climate, and the carbon cycle. This idea was used to help bolster the theory of plate tectonics.
