Question : Which of the following is a non-renewable resource?
Option 1: Wind energy
Option 2: Geothermal energy
Option 3: Fossil fuels
Option 4: Hydroelectric power
Correct Answer: Fossil fuels
Solution : The correct answer is (c) Fossil fuels
Fossil fuels, such as coal, oil, and natural gas, are considered non-renewable resources. They are formed from the remains of plants and animals that lived millions of years ago and have undergone geological processes to become energy-rich substances. Fossil fuels are finite in quantity and take millions of years to form, making them non-renewable on human timescales. Their extraction and combustion release carbon dioxide and other greenhouse gases, contributing to climate change and environmental pollution.
