Chunking is a learning technique that consists in grouping smaller pieces of information into larger groups. A common example is remembering phone numbers: instead of remembering each individual digit, we divide them into groups of three or two.
In the example, the area code is probably one "chunk" of information, and the rest of the number is divided into other groups.
when farmers started noticing these "clear rocks" they decided to trade them for food and supplies and thats when the diamond craze started. it caused thousands of immigrants to move to america.
