How can a terrace sequence help interpret climate change?
Answer and explanation
Correct answer: Alternating phases of incision and deposition can show past discharge and sediment conditions
River terraces are former valley floors preserved above the present channel. A sequence of terraces records repeated phases of deposition and later incision, which may reflect changes in discharge, sediment supply, base level, tectonic uplift, or climate. By dating and comparing terrace levels and deposits, researchers can infer past environmental conditions. Therefore option A is the best answer; terraces are not exclusively coral or cave-age indicators.
