Answer 1

The answer to that is true

Answer 2

True

Step-by-step explanation:

Varves are the seasonal variation in sedimentation observed in lakes or marine environment. Glacial varves are formed in glacial lakes due to difference in deposition pattern between melting and non melting season. There are two types of bands, moisture retaining dark clay rich bands and dry sandy or silty bands. Non melting season is responsible for dark bands whereas melting season is responsible for light bands.
