Interactive Mind Map: Natural Resources and Environmental Impact
Natural Resources
- Life depends on soil, water, air, and energy from the Sun
- Earth is the only planet with life
- Types of resources: Renewable and Non-renewable
- Importance for ecosystems and human survival
Biosphere
- Interaction of Lithosphere, Hydrosphere, and Atmosphere
- Abiotic: Air, water, soil
- Biotic: All living organisms
- Role of ecosystems in balancing life forms
- Human impact on the biosphere
Atmosphere
- Composed of gases: Nitrogen, Oxygen, Carbon Dioxide, and Water Vapour
- Role in maintaining Earth’s temperature (Greenhouse Effect)
- Air Pollution: Acid Rain, Smog from burning fossil fuels
- Movement of Air: Winds due to uneven heating
Water
- Covers 75% of Earth's surface
- Essential for life
- Freshwater found in rivers, lakes, and underground
- Water Pollution: Agricultural runoff, sewage, industrial waste
Soil
- Outer layer of Earth, rich in nutrients
- Soil formation: Physical, chemical, and biological processes
- Contributors: Sun, water, organisms
- Soil Pollution: Improper chemicals and waste dumping
Biogeochemical Cycles
- Water Cycle: Evaporation, condensation, precipitation
- Nitrogen Cycle: Fixation by bacteria, conversion to nitrates for plants
- Carbon Cycle: Exchange between atmosphere, plants, animals, and Earth
- Oxygen Cycle: Produced by plants, consumed by animals
Greenhouse Effect
- Atmosphere traps heat, maintaining Earth's temperature
- Ozone layer absorbs harmful UV rays
- Depletion of ozone caused by CFCs
Pollution
- Air Pollution: Harmful gases and particulate matter
- Water Pollution: Contamination from industries, sewage, runoff
- Soil Pollution: Degradation due to improper chemical use
- Impact: Degradation of quality of life and biodiversity
Conservation of Natural Resources
- Sustainable use of resources
- Methods: Reduce, Reuse, Recycle
- Renewable energy, water conservation, afforestation
