Final answer:
Natural gas is not a renewable resource because it is a fossil fuel that is used up faster than it can be replenished by natural processes. In contrast, sunlight, wind, and water are renewable resources that can be sustainably used without depletion.
Step-by-step explanation:
The natural resource that is not renewable among the options provided is natural gas. Renewable resources include sunlight, wind, and water, because they are naturally replenished at a rate that allows for sustainable extraction. Natural gas, however, is a fossil fuel that took millions of years to form and is used up much faster than it can be replenished by natural processes, making it nonrenewable.
Renewable energy sources, like sunlight and wind, cannot be used up and are considered infinite for practical purposes within human timescales. On the other hand, nonrenewable resources like natural gas exist in finite amounts and can be depleted. Nonrenewable resources can cause environmental concerns, such as the production of carbon dioxide when burned, which contributes to global warming.
