Study Notes
Petroleum
- Also known as mineral oil or crude oil, petroleum is a vital liquid mineral.
- Products derived from petroleum include petrol, diesel, cooking gas, and kerosene.
- Found deep within the Earth's crust.
Nuclear Energy
- Utilizes radioactive materials, primarily uranium, to generate energy.
- Heat is produced when neutrons collide with uranium fuel rods in reactors.
- This heat converts water into steam, which drives turbines to generate electricity.
Renewable vs. Non-renewable Resources
Renewable Resources
- Can be replaced naturally in a short time or recycled.
- Examples include wind energy, solar power, hydroelectricity, and geothermal energy.
- Reusable and recycled multiple times without depletion.
- Environmentally friendly; minimal to no harm caused when utilized.
Non-renewable Resources
- Cannot be replaced or require millions of years for natural processes to regenerate.
- Examples include petrol, coal, natural gas, and nuclear energy.
- Once consumed, these resources cannot be reused or recycled.
- Large environmental harm due to emissions from usage.
Definition of Resources
- Resources are materials found in the environment, utilized by living beings for various needs.
Natural Resources
- Essential for human survival, examples include air, water, woods, animals, and minerals.
- Man-made resources arise when natural items are enhanced to increase their value.
Types of Natural Resources
- Classified based on availability for human consumption as renewable and non-renewable.
Renewable Resources Detailed Examples
- Solar Energy: Generated from sunlight; vital for photosynthesis in plants.
- Wind Energy: Uses air movement for energy; crucial for photosynthesis and respiration in organisms.
- Hydro Energy: Generated from the movement of water; utilized for electricity generation from rivers or dams.
- Soil: Provides the essential layer for plant growth, contributing significantly to food production.
- Biogas: A mixture of gases from the breakdown of organic materials, commonly used as fuel, especially in rural areas.
Non-renewable Resources Detailed Examples
- Fossil Fuels: Non-renewable; includes coal, natural gas, and petroleum; limited supply leading to rising energy prices.
- Coal: Used for electricity generation, fuel, and in industrial processes.
- Natural Gas: Also referred to as compressed natural gas; burns efficiently, providing a large amount of heat and an excellent source of hydrogen.
