Q1. “Mamba and Peter stay in two different parts of the world and lead very different lives” – Why?

Ans: This difference is because of the differences in the quality of land, soil, water, natural vegetation, animals and the usage of technology. The availability of such resources is the main reason places differ from each other.
Q2. What are the main reasons of uneven distribution of population?
Ans: The uneven distribution of population in different parts of the world is mainly due to varied characteristics of land and climate.
The rugged topography, steep slopes of the mountains, low-lying areas susceptible to water logging, desert areas, thick forested areas are normally sparsely populated or uninhabited.
Plains and river valleys offer suitable land for agriculture. Hence, these are the densely populated areas of the world.

Physical factors – such as topography, soil, climate, minerals and availability of water.
Human factors – such as population and technology are also important determinants of land use pattern.
Q5. What is common property resources?
Ans: Community land is owned by the community for common uses like collection of fodder, fruits, nuts or medicinal herbs. These community lands are also called  common property resources.

I) People and their demands are ever growing but the availability of land is limited.
II) The quality of land also differs from place to place.
III) People started encroaching the common lands to build up commercial areas, housing complexes in the urban areas and to expand the agricultural land in the rural areas.
IV) Today the vast changes in the land use pattern also reflect the cultural changes in our society.
V) Land degradation, landslides, soil erosion, desertification are the major threats to the environment because of the expansion of agriculture and constructional activities.
