Quizplus · Accepted Answer

Varves are annual layers found in some sedimentary environments which are characterized by a pair of layers consisting of a light-colored layer rich in silt deposited during the summer and a dark, fine-grained layer rich in clay deposited during the winter. This seasonal cycle results in distinct varves that can be used to study past climates and environments.
