Answer 2

The method used is Sieving.

• It is a separation process in which two or more components are isolated from a mixture based on their size differences.
• It is used to separate things when the item size is too tiny to pick by hand or when the quantity is too huge.
• A sieve with appropriately sized pores is utilised. The sieve keeps the larger particles while allowing the smaller ones to flow through.
• A common example is to split sand from gravel.
