Final answer:
Coal is formed from ancient plant remains in swamps and bogs, subjected to pressure and heat over time. It is considered nonrenewable because it takes millions of years to form and our usage is faster than its natural replenishment.
Step-by-step explanation:
Coal Formation
Coal is formed from the remains of ancient plants that lived and died millions of years ago. These plants accumulated in swamps and bogs, where they were subjected to high pressure and heat over time.
Why Coal is Nonrenewable
Coal is considered a nonrenewable resource because its formation takes millions of years, and the rate at which we are using coal is much faster than its natural replenishment. Once coal is extracted and burned for energy, it cannot be replenished in a human lifetime.
Example of Nonrenewable Resource
An example of another nonrenewable resource is oil. Like coal, oil also takes millions of years to form and its extraction is faster than its renewal.
