Is folding aluminum foil a chemical or physical change?

Aluminum foil is a physical change. A further explanation is given below.

Explanation:

The processing of aluminum foil starts with either a succession of cool rolling procedures, wherever another density including its aluminum alloy becomes diminished by half amongst every method.  Aluminum foil modified thickness and weight, but it would be an aluminum sheet, so it would be a physical transition or change.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
