The term "varves" refers to the two distinct layers of sediment that are deposited annually in lakes that freeze and thaw each year. These layers consist of a light-colored layer of coarse sediment that is deposited in the summer months when the lake is ice-free, and a dark-colored layer of fine sediment that is deposited during the winter months when the lake is frozen over. The alternating light and dark layers create a distinct pattern that can be used to accurately date the sediment and track changes in the environment over time. The other answer choices are not accurate descriptions of the sediment layers found in these types of lakes.
