Study Notes
Non-renewable and Renewable Resources
- Non-renewable resources are finite and cannot be replenished or regenerated at the rate they are consumed.
- Examples of non-renewable resources include fossil fuels like coal, oil, and natural gas.
- Renewable resources are replenished naturally and can be used repeatedly without running out.
- Examples of renewable resources include sunlight, wind, water, and biomass.
Energy Sources
- Fossil fuels (coal, oil, and natural gas) provide energy through combustion, releasing carbon dioxide and other pollutants when burned.
- Renewable energy sources include:
- Solar energy (from sunlight)
- Wind energy
- Hydroelectric energy (from flowing water)
- Biomass energy (from organic materials)
- Geothermal energy (from heat within the Earth)
- Advantages of renewable energy:
- Sustainable
- Reduces greenhouse gas emissions
- Decreases dependence on finite resources
- Challenges of renewable energy:
- Intermittency (some sources are not always available)
- Initial investment costs
- Land use requirements
The Water Cycle
- The water cycle is the continuous movement of water on, above, and below the surface of the Earth.
- Processes in the water cycle include:
- Evaporation (conversion of liquid water into vapor)
- Condensation (conversion of water vapor into liquid water)
- Precipitation (water falling from the atmosphere)
- Runoff (movement of water over land into bodies of water)
- Infiltration (water seeping into soil and replenishing underground water sources)
- Transpiration (release of water vapor from plants into the atmosphere)
Water Management
- Water management involves the conservation, distribution, and purification of water resources to meet human and environmental needs.
- Conservation efforts:
- Reduce water waste
- Promote efficient water use
- Protect ecosystems that provide water
- Distribution ensures equitable access to clean water for:
- Drinking
- Sanitation
- Agriculture
- Industry
- Ecosystems
- Water purification involves treating contaminated water to make it safe for human consumption and ecosystem health, using methods such as:
- Filtration
- Chlorination
- Desalination
