Explain a ‘‘Healthy City’’ in the light of suggestions made by World Health Organisation.
Explain any five factors that influence the distribution of population in the world.
Factors that influence the distribution of population in the world are:
(i) Availability of water- It is the most important factor for life. So, people prefer to live in areas where fresh water is easily available.
(ii) Landforms- People prefer living on flat plains and gentle slopes. This is because such areas are favourable for the production of crops and to build roads and industries.
(iii) Climate- An extreme climate such as very hot or cold deserts are uncomfortable for human habitation. Areas with a comfortable climate, where there is not much seasonal variation attract more people.
(iv) Soil –Fertile soils are important for agricultural and allied activities. Therefore, areas which have fertile loamy soils have more people living on them as these can support intensive agriculture.
(v) Urbanization- Cities offer better employment opportunities, educational and medical facilities, better means of transport and communication.
