Natural Resources — Telangana (SSC) Class 10 Science Solutions (Free)

Natural resources: materials and energy sources provided by nature used by humans. - Renewable resources: can be replenished naturally (water, forests, soil, sunlight, wind) Regenerate within human lifetime if used sustainably - Non-renewable resources: finite, cannot be replaced once exhausted (fossil fuels, minerals, metals) Took millions of years to form Wise management essential to ensure availability for future generations

Sustainable forest management: using forests to meet current needs without compromising future use. - Practices: a) Selective logging: harvest only mature trees b) Afforestation: planting new forests c) Agroforestry: combining agriculture with tree planting d) Protection of endangered species and biodiversity Importance: - Maintains forest ecosystems and biodiversity - Prevents soil erosion and maintains water cycles - Provides continuous timber and non-timber products - Combats climate…

Water conservation: efficient use and protection of freshwater resources. - Need for conservation: a) Only 3% of Earth's water is freshwater b) Population growth increases demand c) Pollution reduces available clean water d) Climate change alters rainfall patterns - Conservation methods: a) Reduce agricultural water use through drip irrigation b) Fix leaks in pipes c) Rainwater harvesting and groundwater recharge d) Wastewater treatment and reuse e) Prevent water pollution Wi…

Importance of soil: - Provides nutrients for plant growth - Supports biodiversity (bacteria, fungi, insects) - Filters and stores water - Stores carbon Soil degradation causes: - Erosion from wind and water - Loss of fertility from overfarming - Contamination from chemicals and waste Prevention methods: - Contour plowing and terracing to prevent erosion - Crop rotation to maintain soil nutrients - Use of organic matter and compost - Cover crops to protect soil - Reduce chemical fertilizer and …

Fossil fuels: coal, petroleum, and natural gas formed from dead organisms over millions of years. - Advantages: energy-dense, established infrastructure - Disadvantages: a) Non-renewable, will be exhausted b) Burning releases CO2, causing global warming and climate change c) Air pollution from sulfur dioxide and nitrogen oxides d) Mining causes habitat destruction and water pollution d) Oil spills damage marine ecosystems - Alternatives: renewable energy (solar, wind, hydroelectric, g…
