Which is the best analogy for classification? classification is like setting up a phone tree in which one person calls the next two people, and those people call the next four people. classification is like creating an alphabetized list of people based on their last names. classification is like organizing a car wash where everyone brings needed items and then works. classification is like organizing a closet by hanging clothes together based on their type, color, and season.

Classification is the act of grouping things by shared qualities or characteristics. 

With your given options to the most accurate analogy would be the organization of clothes based on type, color and season. 

Alphabetizing implies a specific order is necessary which with classification it is not. The car wash analogy is incorrect because those people were assigned specific traits (in this case their items/job) but when classifying you do not assign any trait, you sort them as is. 

It should be cryosphere and hydrosphere
