Final answer:
Coal is formed from ancient vegetation over millions of years, making it nonrenewable due to the extended formation process, and exploration of renewable energy sources as alternatives.
Explanation:
Coal formation: Coal is formed from ancient swamp vegetation that went through a process of decomposition and compaction over millions of years, resulting in the creation of coal deposits.
Nonrenewable nature of coal: Fossil fuels like coal are considered nonrenewable because they take millions of years to form and once mined, they cannot be replenished within a human lifespan. Burning coal releases pollution, including carbon dioxide, contributing to environmental issues.
Alternative energy sources: Scientists are exploring renewable energy sources like solar, wind, and hydroelectric power to replace coal as an energy source and mitigate environmental impacts.
