The following statements about renewable and nonrenewable resources are true:
- Nonrenewable resources are abundant but will not last forever. - This is true; nonrenewable resources, such as fossil fuels, are finite and will eventually be depleted.
The other statements can be evaluated as follows:
-
Renewable resources are expensive to produce. - This can vary widely depending on the type of renewable resource and technology used; it's not universally true.
-
Renewable resources are used faster than they are replenished. - This is typically false; renewable resources are meant to be replenished naturally over time (e.g., solar energy, wind energy).
-
Renewable and nonrenewable resources both produce clean energy. - This is misleading; while renewable resources generally produce cleaner energy with lower emissions, many nonrenewable resources (like coal and oil) produce significant pollution.
-
Nonrenewable resources are easy to produce. - This can depend on many factors such as technology and location, and generally, they can be both easy and difficult to extract based on circumstances.
-
Renewable resources require more maintenance than nonrenewable resources. - This can vary by technology; some renewable energy sources, like wind turbines and solar panels, can require maintenance, but this isn't a universal truth applicable to all.
So, the only clear statement that is true is: Nonrenewable resources are abundant but will not last forever.
