2) Climate Most of the areas of the earth having density less than two persons/sq. km are not favorable for settlement because of their unfavorable climate. Areas of cold climate-North Siberia‚ North Canada‚ Alaska etc. have low density of population. Hot and arid regions of -Sahara‚ Kalahari Desert in Africa‚ Great Australian Desert etc are not suitable for human settlement. In tropical regions due to heavy rain and temperature‚ the density of population is

Make a prediction for high population density; record it in the data table‚ and run the simulator three times‚ recording that data in the table. Answer the following: 3. What could be done to prevent the spread of disease in a low population density? 4. What kinds of challenges would high population density present to these precautions

in human demography‚ the population is the set of humans in a given area. Population density is a common biological measurement and is often used by conservationists as a more appropriate measure than absolute numbers. If there are low population densities‚ extinction may be in the future of the species life‚ but is unlikely to occur and a reduced reproduction rate can also be a result. Low population densities result in reproduction to decline due to the increased problems with locating mates‚

most major cities in the world with high population densities are likely to result in clustering of buildings due to constraints of land resources. Urban settlements tend to be clustered as people in urban settlements are mainly involved in activities like business and manufacturing. All these require transportation and services. Thus‚ having settlements clustered together enables them to have easy access to transportation. Population density here is usually higher than in rural settlements and

Rhodes Rhodes is a suburb that is located 16 km west of the Sydney CBD. It is the local government area of Canada Bay (merged council of Drummoyne and Concord). As you can see from the map‚ Rhodes lies on a peninsula on the southern bank of Parramatta River. The district can be categorized in 3 different sections due to its different characteristics. Eastern side- East of Concord Road is mainly residential areas and parklands that are situated in front of Parramatta River. Central- Between Concord

For example‚ in Bangladesh‚ there is the one of the highest population densities‚ 2‚791 persons per square mile. The majority of people living in Bangladesh partake in low productivity manual farming which contributes to its high level of poverty. Comparatively‚ in Western Europe‚ countries such as Belgium and the Netherlands also have high population densities but use mechanised farming and high-tech industries

Earthquakes: Why do some places suffer more than others? Whilst earthquakes are perhaps the most frequently occurring natural hazard‚ their impact on people‚ property and communities varies enormously from one place to another. It is possible to identify a number of factors that cause some places to suffer more than others. Whilst some are large scale and are to do with tectonic location‚ others are decided at a much more local scale‚ and relate to building design and levels of preparedness. Perhaps

Urban settlements 2. Suburban settlements 3. Rural settlements What is settlement? Settlement refers to an area where people become fixed for residential purposes. Urban Settlements An urban area is characterized by high population density and vast human features in comparison to surrounding areas. Urban areas are created and further developed through the process of urbanization. Urban areas may be cities or towns. These areas have great accessibility to amenities such as electricity
