This document discusses different types of land resources including soil, natural vegetation, wildlife, and how land is used for cultivation, grazing, buildings, mining, and manufacturing. It also discusses physical factors like topography, soil, climate, water availability, and minerals that influence land use as well as economic and human factors like population, industrialization, and development level. The document also summarizes the three stages of soil formation and causes and methods of soil erosion. It provides key facts about water resources and their importance for irrigation, industry, drinking, power, and recreation as well as factors responsible for water scarcity. The document also discusses the role of natural vegetation in supporting ecosystems and providing resources and the importance of wildlife for food, pol

10. Distribution of land

11. 3 stages of soil formationStage – 1
Soil formation starts due to weathering of
rocks and it develop a organic layer.
Stage – 2
Bacteria and micro-organisms act on the
remains of plants and other organic material
forming humus.
Stage -3
Humus helps loose soil grains to stay –
together and also makes the soil more fertile.

12. Soil erosion - removal of soil
Causes of soil erosion
Deforestation
Over grazing of land
Improper farming techniques
wind and rainfall

13. Methods to conserve soil
Afforestation
Mulching
Contour barrier
Rock dam
Terrace farming
Intercropping
Contour ploughing
Shelter belts

15. Hard facts about water
71% of earth surface is water.
97% of earth water is salty found in
oceans.
3% of earth water is fresh water.
Two-third of fresh water is locked in
northern and southern poles
Only one- third is found in lakes, rivers,
streams and aquifiers.

16. Importance of water
Irrigation
Industries
For formation of water
Drinking
Power generation
transportation
For recreational activities like
swimming, boating and fishing

17. Factors responsible for water
scarcityGrowing population
Commercialization of agriculture
Variatation in seasonal and annual
precipitation
Industrializatation and urbanization
Over -utilization and mis- utilization of water
pollution

18. Natural vegetation and wildlife
Vegetation supports function of biosphere.
It regulates flow of water, carbon and
nitrogen.
Vegetation affects soil properties.
Vegetation is important in use of fossil fuels as
energy source.
Source of energy in atmosphere.

19. Natural vegetation and wildlife
Wildlife includes animals, birds, insects and
aquatic life.
They give us milk, meat, hides and wool
Insects like bees gives honey.
Insects help in pollination of flowers.
Birds like vultures decompose dead livestock
and cleans environment.

22. Human resources
This refers to the number and abilities
(mental and physical) of the people of the
people . People can make the best use of
nature to create more resources when they
have the knowledge, skill and the technology
to do so. That is why human beings are special
resources. People are human resources.
Education and health help in making people a
valuable resources.

25. Human made resources
Sometimes natural substances become
resources only when their original form has
been changed. Iron ore was not a resources
until people learnt to extract iron from it.
People use natural resources to make
buildings, bridges, roads, machinery, and
vehicles , which are known as human made
resources. Technology is also a human made
resources.
