Those which can get renewed or replenished quickly are called as Renewable resources. They are also called as Inexhaustible resources. So that's why.

Inexhaustible Resources

Inexhaustible resources are those resources that can be continually replenished or renewed and will never run out. These resources are also known as renewable resources. They are usually derived from nature and can be replenished naturally within a relatively short period of time.

Examples of inexhaustible resources include:

- Solar energy: sunlight can be converted into electricity through solar panels. As long as the sun continues to shine, solar energy will be available.
- Wind energy: wind turbines can generate electricity from the wind. Wind is a natural occurrence that will continue to exist as long as the earth rotates.
- Geothermal energy: heat from the earth's core can be used to generate electricity. This heat is constantly replenished by the earth's natural processes.
- Water energy: hydropower can generate electricity from the movement of water. Water is a renewable resource as it can be replenished through the water cycle.

Non-renewable resources

Non-renewable resources, on the other hand, are resources that cannot be replenished in a short period of time. These resources are finite and will eventually run out. They are usually derived from minerals and fossil fuels that took millions of years to form.

Examples of non-renewable resources include:

- Coal: coal is a fossil fuel that is formed from the remains of prehistoric plants. It takes millions of years to form, and once it is mined, it cannot be replaced.
- Oil: oil is another fossil fuel that is formed from the remains of prehistoric animals and plants. It is a finite resource that will eventually run out.
- Natural gas: natural gas is also a fossil fuel that is formed from the remains of prehistoric plants and animals. Like oil and coal, it is a finite resource.

Conclusion

In conclusion, inexhaustible resources are resources that can be continually replenished and will never run out. They are derived from nature and can be replenished naturally within a relatively short period of time. Non-renewable resources, on the other hand, are finite resources that will eventually run out. They are derived from minerals and fossil fuels that took millions of years to form.
