Study Notes
Natural Resources
- All living beings require certain materials to survive, including air, water, and soil, which are referred to as resources of the earth.
- Natural resources are materials that exist freely in nature, on the earth.
Types of Natural Resources
Renewable Resources
- Renewable resources are those that are never depleted or lost, or can be replaced in a short period of time.
- Examples of renewable resources include air, sunlight, and water.
- However, some renewable resources may become exhaustible if they are used at a faster rate than they are renewed.
- For example, groundwater can become an exhaustible resource if it is used up fast due to disturbance in the water cycle or a growing population.
Non-Renewable Resources
- Non-renewable resources are those that once used up cannot be replaced in a short time.
- They are also called exhaustible resources as their availability is limited.
- Examples of non-renewable resources include fuels like coal, petroleum, and natural gas.
- Once non-renewable resources are exhausted, they cannot be produced again as it takes millions of years to form these fuels.
Learn about the natural resources available on earth, such as air, water, and soil, and how humans utilize them in different ways to generate energy, obtain essential needs, and more. Test your knowledge of the importance of natural resources and their applications.
