Study Notes
Latitude and Longitude
- Definition: Latitude and longitude are used to locate points on the Earth's surface.
-
Latitude:
- Measures distance north or south of the equator (0° to 90°)
- Lines of latitude are parallel to the equator
-
Longitude:
- Measures distance east or west of the prime meridian (0° to 180°)
- Lines of longitude converge at the poles
Fossil Fuels
- Definition: Non-renewable energy sources formed from ancient plants and animals.
-
Types:
- Coal: Formed from plant remains, used for electricity generation and industrial processes.
- Oil: Formed from marine organisms, used for transportation and industrial processes.
- Natural Gas: Formed from plant and animal remains, used for electricity generation and heating.
Wind Energy
- Definition: Renewable energy harnessed from wind using turbines.
-
Advantages:
- Abundant resource
- Zero emissions
- Low operating costs
-
Limitations:
- Intermittent energy source
- Visual impact of turbines
Solar Power
- Definition: Renewable energy harnessed from sunlight using photovoltaic cells.
-
Advantages:
- Abundant resource
- Zero emissions
- Low maintenance
-
Limitations:
- Intermittent energy source
- High upfront costs
Biomass Energy
- Definition: Renewable energy derived from organic matter (plants, waste).
-
Sources:
- Forestry residues
- Agricultural waste
- Municipal waste
-
Conversion methods:
- Combustion: Burning biomass to produce electricity or heat.
- Anaerobic digestion: Converting biomass into biogas (CH4, CO2).
Geothermal Energy
- Definition: Renewable energy harnessed from Earth's internal heat.
-
Sources:
- Hot springs
- Geysers
- Magma
-
Applications:
- Electricity generation
- Heating and cooling
- Industrial processes
