DEFINITION
What does natural resource mean?
Natural resources are materials created in nature that are used and usable by humans.
What is the classification of natural resources based on the basis of recovery rate?
They can be categorized as renewable resources and non-renewable resources.
How much time does it take to replenish non-renewable resources?
It takes millions of years to replenish them.
What es economic value?
Production of things from natural resources.
Uses of air.
Air is required for all living things for breathing.
Use to produce wind energy.
What are biotic resources?
Resources obtained from the biosphere.
What is the classification of natural resources based on the basis of origin?
On the basis of origin, natural resources may be divided in biotic and abiotic resources.
Talk about the rate of replenishment/recovery, and the rate of consumption of renewable resources.
Resources from a human use perspective are classified as renewable so long as the rate of replenishment/recovery exceeds that of the rate of consumption.
Examples of legal value
Clean air, freshwater, healthy anima,l and human beings
Uses of soil.
Used as the primary nutrient source for plants. It is the habitat of many organisms.
What are Abiotic resources?
Resources that come from nonliving, non-organic materials
What is the classification of natural resources based on the stage of development?
Considering their stage of development, natural resources may be referred to as potential resources, actual resources, reserve resources, and stock resources.
Talking about emissions of carbon dioxide, talk about the advantage of renewable resources.
Example of aesthetic value.
The beauty of village, roads, ponds and their agricultural fields.
Provide light, energy and help to plants for making their foods
What are renewable resources?
Resources that can be replenished naturally.
Define each term of the classification of natural resources based on their stage of development.
•Potential resources — Potential resources are those that may be used in the future—for example, petroleum in sedimentary rocks that, until drilled out and put to use remains a potential resource
•Actual resources — Those resources that have been surveyed, quantified and qualified, and are currently used in development, such as wood processing, and are typically dependent on technology
•Reserve resources — The part of an actual resource that can be developed profitably in the future
•Stock resources — Those that have been surveyed, but cannot be used due to lack of technology—for example, hydrogen
How do fossil fuels form?
Fossil fuels are formed from the fossilized remains of prehistoric organisms.
Every 20 years, how much does our consumption of fossil fuels increase?
Our consumption of fossil fuels has nearly doubled about every 20 years.
Uses of wood/tree.
Used as a construction material. Used to make utensils, furniture, and sporting equipment.
What are non-renewable resources?
Non-renewable resources form slowly or do not naturally form in the environment.
What are the three methods of categorizing natural resources?
Natural resources can be categorized on the basis of origin, stage of development, and the basis of recovery rate.
What is the percentage of energy consumption of fossil fuels in the world?
Fossil fuels currently account for about 90% of the world´s energy consumption.
Present the fossil fuels´ percentage of provision of the world´s electrical power and of the world´s total energy demands.
Fossil fuels provide around 66% of the world´s electrical power and 95% of the world´s total energy demands.
Uses of water.
Used in household, agriculture, and transportation. It is used for generating electricity and as a fuel.
