NCERT Textbook Alignment & SA1/SA2 Distribution
SA1 (Term 1): Resources and Chapter 2 topics related to Land, Soil, and Water.
SA2 (Term 2): Natural Vegetation and Wildlife along with later Geography chapters.
1. LAND: Our Most Precious Natural Resource
What is Land?
Land is the solid part of the Earth’s surface that covers approximately 30% of the planet’s total area. Large portions of land are unsuitable for human settlement due to rugged mountains, deserts, forests, or harsh climatic conditions.
Important NCERT Fact: Around 90% of the world’s population occupies only 30% of land area.
Factors Affecting Land Distribution and Population
Sparsely Populated Areas:
• Rugged mountains and steep slopes
• Waterlogged regions
• Polar and desert regions
• Thick forests
Densely Populated Areas:
• Plains and river valleys
• Fertile agricultural land
• Areas with adequate water supply
Land Use Pattern
Land use means the productive utilization of land for different human activities such as:
• Agriculture
• Forestry
• Mining
• Construction
Factors Determining Land Use
Physical Factors:
• Topography
• Soil type
• Climate
• Minerals
• Water availability
Human Factors:
• Population density
• Technology
• Economic development
Land Ownership Classification
Private Land: Owned by individuals or families.
Community Land: Owned and used collectively by communities.
Common Property Resources: Shared resources such as village ponds, forests, and grazing grounds.
Land Degradation
Land degradation refers to the decline in land quality and productivity.
Major Causes:
• Deforestation
• Overgrazing
• Excessive use of chemicals
• Mining and construction
• Soil erosion and landslides
Effects of Land Degradation
• Reduced agricultural productivity
• Desertification
• Biodiversity loss
• Floods and landslides
• Water scarcity
Conservation of Land Resources
Methods:
• Afforestation
• Land reclamation
• Regulated use of fertilizers and pesticides
• Checking overgrazing
• Contour ploughing
• Terrace farming
2. SOIL: The Foundation of Life
What is Soil?
Soil is the thin layer of grainy material covering the Earth’s surface. It contains minerals, organic matter, and weathered rocks.
Memory Trick: SOIL = Surface Organic & Inorganic Layer
Soil Profile
A soil profile contains different layers called horizons:
Horizon O: Organic layer containing leaves and humus.
Horizon A: Topsoil rich in minerals and humus.
Horizon B: Subsoil containing clay and minerals.
Horizon C: Parent rock layer.
Factors of Soil Formation
Soil formation takes hundreds to millions of years.
Main Factors:
• Parent rock
• Climate
• Topography
• Organic material
• Time
CBSE Alert: Temperature and rainfall are the two main climatic factors responsible for soil formation.
Weathering
Weathering is the breaking up and decay of rocks due to:
• Temperature changes
• Frost action
• Plant and animal activities
• Human activities
Soil Conservation Methods
Mulching: Covering soil with organic matter to retain moisture.
Contour Barriers: Barriers along slopes to slow water flow.
Rock Dams: Rocks stacked to prevent gully erosion.
Terrace Farming: Step farming on hills and mountains.
Intercropping: Growing different crops together.
Contour Ploughing: Ploughing parallel to contours.
Shelterbelts: Planting rows of trees to reduce wind erosion.
Exam Alert: Terrace farming is the best method to prevent soil erosion on steep slopes.
3. WATER: The Elixir of Life
Water covers around 75% of the Earth’s surface. However, most water is saline ocean water.
Important Facts:
• 97.3% water is saline
• 2.7% is freshwater
• Less than 1% freshwater is available for human use
The Water Cycle
The water cycle involves:
• Evaporation
• Transpiration
• Condensation
• Precipitation
• Collection
Problems of Water Availability
Main Reasons:
• Uneven distribution of rainfall
• Overexploitation of groundwater
• Pollution
• Population growth
• Climate change
Water Conservation Methods
Afforestation: Helps groundwater recharge.
Rainwater Harvesting: Collecting rainwater for future use.
Canal Lining: Preventing water seepage.
Sprinkler Irrigation: Sprays water like rainfall.
Drip Irrigation: Delivers water directly to roots.
Memory Trick: R-A-I-N-S
R – Rainwater harvesting
A – Afforestation
I – Irrigation methods
N – No wastage
S – Sprinkler & drip systems
4. NATURAL VEGETATION AND WILDLIFE
The Biosphere and Ecosystem
The biosphere is the narrow zone where the lithosphere, hydrosphere, and atmosphere interact.
The life-supporting system of interdependent living beings is called an ecosystem.
Importance of Natural Vegetation
• Provides oxygen
• Protects soil from erosion
• Supports wildlife
• Supplies timber and medicinal plants
• Helps groundwater recharge
Importance of Wildlife
• Maintains ecological balance
• Helps pollination
• Controls pests
• Provides food and useful products
Distribution of Natural Vegetation
The type of vegetation depends mainly on temperature and rainfall.
Heavy Rainfall: Evergreen forests
Moderate Rainfall: Deciduous forests
Low Rainfall: Grasslands
Very Low Rainfall: Thorny bushes
Cold Regions: Tundra vegetation
Types of Forests
Evergreen Forests
• Heavy rainfall regions
• Trees remain green throughout the year
• Dense canopy
Examples: Rosewood, Ebony, Mahogany
Deciduous Forests
• Trees shed leaves in dry season
• Moderate rainfall regions
Examples: Sal, Teak, Neem, Bamboo
Thorny Forests and Scrubs
• Found in dry areas
• Deep roots and thorny leaves reduce water loss
Examples: Acacia, Cactus, Babool
Conservation of Natural Vegetation and Wildlife
Major Threats:
• Deforestation
• Forest fires
• Poaching
• Climate change
• Pollution
Protected Areas
National Parks: Protect ecosystems.
Wildlife Sanctuaries: Protect specific species.
Biosphere Reserves: Conserve biodiversity.
Important Conservation Measures
• Wildlife Protection Act (1972)
• CITES agreement
• Project Tiger
• Van Mahotsav
• Social Forestry
Important Geographical Terms
Land Use: Productive use of land.
Weathering: Breaking down of rocks.
Humus: Organic matter in soil.
Biosphere: Zone where life exists.
Ecosystem: Interdependent living system.
Shelterbelts: Rows of trees preventing wind erosion.
Rainwater Harvesting: Collection and storage of rainwater.
Poaching: Illegal hunting of animals.
