Uranium is non-renewable as it's a heavy metal found in rocks that can take over billions of years to form, and its supply is finite.

Bitumen is non-renewable as it's a form of petroleum that has been subjected to geothermal pressures for millions of years, and reserves are used up more quickly than they are naturally replenished.

Heavy metals like gold and silver are non-renewable as they are elements that form in the earth's crust over geologic time scales and are mined at rates much faster than their natural formation.

Natural gas is seen as non-renewable because it consists of methane and other gases formed from the decay of organic material, taking millions of years to accumulate and is used up faster than it forms.

Phosphorus in the form of phosphate rocks is non-renewable because it's mined from finite deposits that don't regenerate on a human timescale and are depleted by agricultural use.

Crude oil is considered non-renewable as it's created from the decay of tiny sea creatures over millions of years and is extracted faster than nature can replace it.

Peat is deemed non-renewable because it is an accumulation of partially decayed vegetation taking thousands of years to form and is harvested at a rate that exceeds its natural regeneration.
