Study Notes
Natural Resources
- Natural resources are derived from the Earth and are essential for improving human life quality.
- Key natural resources include clean water, fertile soil, and solar energy.
- The interactions between soils, plants, animals, water, and energy create a balanced ecosystem.
Renewable Resources
- Renewable resources result from the natural processes interacting within Earth's systems.
- They regenerate as long as the balance of matter and energy is maintained and unaffected by disasters or human interference.
Nonrenewable Resources
- Nonrenewable resources exist in finite quantities and include fossil fuels, minerals, and ores.
- These resources cannot be regenerated naturally within a human lifespan, making their depletion a critical concern.
Soil & Land Resources
- Soil formation involves mechanical, chemical, and organic processes altering unconsolidated material derived from weathered rocks.
- Soil horizons are layers in soil formed by the downward movement of clay, water, and dissolved ions.
Importance of Land
- Land is the most significant natural resource for agricultural production, but its availability is limited as the population grows.
- Increasing agricultural productivity can be achieved through irrigation and measures to cultivate previously wasted land.
- Urbanization and infrastructure development consume fertile land, impacting food production areas.
Forests
- Forests play a vital role in regulating CO2 levels and support diverse animal habitats, providing medicinal resources.
- Commercial forestry is a significant global industry focused on re-harvesting and finding new lumber sources.
- Key issues in forest management include depletion from natural disasters and human activities, necessitating health and growth monitoring.
Indian Forests
- Over two-thirds of India's forest land (around 31 million hectares) is classified as open forests with less than 40% tree canopy cover.
- This open forest land is emphasized for potential energy production through regeneration.
