Fossil fuels are probably forming deep in the crust somewhere, so why are they considered nonrenewable resources?

• Fossil fuels are not considered nonrenewable resources; they can be replenished easily.
• Fossil fuels are actually renewable resources because they can be formed again in a short period of time.
• Fossil fuels take millions of years to form and cannot be replenished at the same rate they are being consumed.
• Fossil fuels are not formed deep in the crust; they are found near the surface and can be easily extracted.

• Atoms are made up of smaller particles
• Atoms are not particles
• True
