Study Notes
Non-Renewable Resources
- Non-renewable resources, once used, cannot be replaced in our lifetime.
- Examples of non-renewable resources include coal and minerals.
Renewable Resources
- Wind, vegetation, and water are examples of renewable resources.
Biogas Production
- Cow dung is a major raw material for biogas production.
Earth's Surface Covered by Water
- The earth's surface covered by water is approximately 75%.
Ecosystem
- Primary consumers are more than primary producers in an ecosystem.
Natural Resources in India
- India has the largest reserve of iron ore, after Brazil.
Landslide
- A sudden, uncontrolled descent of a mass of earth under the force of gravity is called a landslide.
Plant Water Relations
- Hydroscopic and combined water are stored in xylem tissues of plants.
- Plants use 45% of water for transpiration and 55% for evapotranspiration.
Producer Gas
- The constituents of producer gas are 45% methane and 55% CO2.
Dam Construction
- The main purpose of dam construction is for hydroelectricity, irrigation, and flood control.
Non-Renewable Energy Resource
- Coal and minerals are examples of non-renewable energy resources.
Reducing Emissions
- The United States and World Bank have started reducing emissions from deforestation and forest degradation.
