which one describe the source of natural resources? they are

obtained from the earth and its environment.

Natural resources are materials or substances that exist in the environment and are considered valuable for human use. They are classified into three major categories:

1. Renewable Resources: These resources are replenished naturally over a relatively short period of time. Examples include sunlight, wind energy, fresh water, timber, and agricultural crops.

2. Non-renewable Resources: These resources exist in limited quantities and cannot be easily replenished or regenerated within a short period of time. Examples include fossil fuels (coal, oil, and natural gas), minerals (gold, diamonds, copper), and metals (iron, aluminum).

3. Inexhaustible Resources: These resources are always available and virtually limitless in quantity. They are not depleted by human consumption. Examples include solar energy, geothermal energy, and tidal energy.

It is worth noting that the availability and accessibility of natural resources vary by geographic location, and they play a crucial role in economic development and sustainability.
