Study Notes
Natural Resources
- Occur naturally within environments undisturbed by humans.
- Include substances, energy units, and natural processes.
- Examples include water, air, soil, minerals, coal, forests, crops, and wildlife.
Classification of Natural Resources
-
Origin:
- Biotic: Derived from living organisms (e.g., forests, animals, fossil fuels).
- Abiotic: Derived from non-living, non-organic material (e.g., land, water, air, heavy metals).
-
Development:
- Potential: Resources existing in a region but not yet used.
- Developed: Resources surveyed, quantified, and used currently.
-
Renewability:
- Renewable: Replenished naturally in a given timeframe (e.g., sunlight, air, wind).
- Non-renewable: Formed extremely slowly, with replenishment rates significantly slower than consumption (e.g., minerals, fossil fuels).
Energy Resources
- Energy is the physical ability to do work, measured in Joules (J).
- Power is energy per unit time, measured in Watts (W).
- Used for cooking, heating, lighting, transportation, and manufacturing.
- Renewable Resources: Inexhaustible and regenerated within a period (e.g., sunlight, wind, rain, geothermal).
- Non-Renewable Resources: Exhaustible and not regenerated within a timeframe (e.g., fossil fuels, coal, petroleum, minerals).
- Conventional vs. Non-conventional: Conventional resources are longstanding fuels (coal, petroleum, natural gas, and water), while non-conventional are newer resources (solar, wind, tidal).
Coal
- Composed primarily of carbon; also contains hydrogen, oxygen, and other minor elements.
- Formed from decayed vegetation.
- Widely used as a fuel.
Solar Energy
- The sun's rays used to generate heat or electricity.
- Photovoltaic (PV) Energy: Directly converts sunlight into electricity.
- Solar Thermal Power Plants: Heat a fluid using solar radiation to produce steam, which then generates electricity.
Wind Energy
- Air in motion, generated by uneven heating of the earth's surface.
- Windmills capture wind energy and convert it to rotational energy, used to generate electricity.
- Renewable source of energy.
Hydropower Energy
- Flowing water creates energy, captured and converted to electricity, often using dams.
- Dams store water in reservoirs, releasing it through turbines, which spin generators to produce electricity.
- Renewable, relatively low maintenance.
Geothermal Energy
- Heat from within the earth, used to generate electricity or heat buildings.
- Geothermal energy is derived from the decay of radioactive elements deep underground.
Bio Energy
- Capturing solar energy by plants, converting it into biomass.
- Biomass is a renewable source.
- Used for fuel, as well as other purposes
Nuclear Energy
- Energy released in a nuclear reaction (e.g., nuclear fission).
- Has the potential to generate large amounts of electricity.
Forest Resources
- Essential for many aspects of human life.
- Source of a wide range of resources (timber, food, etc.)
- Critical for regulating the environment (climate, water, biodiversity).
Land Resources
- Finite, valuable, and crucial for human use.
- Soil is one type, which requires sustained management to prevent degradation.
- Soil erosion and land degradation result from a variety of natural phenomena and human activity.
Desertification
- Gradual conversion of productive land to desert-like condition.
- Caused by deforestation, overgrazing, and mineral extraction.
Waste Associated with Mining
- Waste materials produced during mineral extraction (Ore processing) are often discarded through temporary tailings
- Surface and sub-surface mining results in various types of waste
Water Resources
- Essential for life on Earth.
- Include oceans, seas, rivers, ponds, and aquifers (underground water reserves).
