Answer the following question given this paragraph: Several types of stratified deposits form in glacial regions but are not formed directly by the ice. Varves form where lakes are covered by ice in the winter. Dark, fine-grained clays sink to the bottom of the lake in winter. Melting ice in the spring brings running water that deposits lighter colored sands. Each alternating dark/light layer represents one year of deposits. Q: What type of stratified deposit is formed where lakes are covered by ice in the winter? Choices: - telomeres - glacier - tangles - varves A:
varves
