Question

1. a form of absolute dating that is used to date sedimentary deposits in glacial lakes is ______.

radio carbon dating
rate of deposition
rate of erosion
varve count

Explanation:

Varves are annual sediment layers in glacial lake deposits. Counting these distinct, yearly layers provides an absolute dating method specific to these sedimentary deposits, as each varve represents one year. Radiocarbon dating is not specific to glacial lake sediments, while rate of deposition/erosion are relative or indirect dating methods, not absolute annual counts.

Answer:

D. varve count
