What does the formation of erratics and kettle lakes have in common?

Answer;

-Both kettel lakes and erratics are the results of materials that were deposited by a glacier as it gets retreated.

Explanation;

-Kettles are depressions left behind after partially-buried ice blocks melt. They are formed as a result of blocks of ice calving from glaciers and becoming submerged in the sediment on the out wash plain. Many are filled with water, and are then called kettle lakes.

-An erratic is a boulder transported and deposited by a glacier having a lithology different than the bedrock upon which it is sitting. Erratics are useful indicators of patterns of former ice flow.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
