Answer:
The La Brea tar pits are an example of a fossil fuel that takes centuries to create.
Step-by-step explanation:
The tar pit is an area where tar has surfaced in the ground for tens of thousands of years, forming hundreds of sticky pools, which during this time trapped animals and plants that fell and were fossilized. The result was an incredibly rich collection of fossils dating back to the Last Ice Age. Because of the time these fossils were formed, we can conclude that the La Brea tar pits are an example of a fossil fuel that takes centuries to create.
