Quizplus · Accepted Answer

Varves are layers of sediment typically found in glacial lakes that were deposited annually as a result of the melting of ice sheets. The layers can often be distinguished by differences in color, texture, and composition, and can be used to study past climate and environmental changes. Tree rings and pollen are also commonly used to study past environments, but they are not directly related to sedimentation in glacial lakes. Ice cores are typically retrieved from ice sheets and glaciers, rather than from lakes. Contextual seriation is a dating method used in archaeology, and is not related to sedimentation or glacial lakes.
