Population Density

Correct answer: B. Double

The same population becomes more concentrated in a smaller area. Exam tip: remember density increases when area decreases.

Correct answer: C. As both opportunity and pressure

High density can support markets and services but can also increase pressure. Exam tip: give a balanced answer.

Correct answer: B. People live far apart and distance is high

Sparse settlement increases distance and access challenges. Exam tip: connect low density with service delivery.

Correct answer: B. ( \text{Density}=\frac{\text{Population}}{\text{Area}} )

Density is calculated by dividing total population by total area. Exam tip: do not reverse the formula.

Correct answer: D. Density will increase

When area remains same increase in population raises density. Exam tip: remember the direct relation between population and density.

Correct answer: A. Pressure on resources

The direct answer is A: pressure on resources. High density means many people are living in relation to the available land. If resources per person are already few, more people may depend on the same limited water, food, land, energy and public facilities. This can create competition, shortages and greater demand. Option A is correct because it directly describes the main concern created by many people sharing limited resources. Option B, increase of area, does not automatically happen when density is high; the land may remain the same. Option C is wrong because high density does not make the population become zero. Option D is unrelated; a map does not disappear because resources are limited. The exact reasoning is: high density increases the number of users, limited resources restrict supply, and the gap creates pressure. This does not mean every dense place must fail, because good planning, conservation and fair distribution can help. Memory cue: many users plus few resources equals resource pressure.

Correct answer: A. Difference in local density

Average density can hide internal dense and sparse areas. Exam tip: distinguish average from local pattern.

Correct answer: A. When the area is resource rich or border located

Population density tells us how many people live in a unit of area, but it does not by itself show the total importance of a place. A sparsely populated region may contain minerals, forests, water, energy resources, or fertile land. It may also lie on an international boundary and therefore have strategic importance. National planning must consider such wider economic, environmental, and security needs, not only the number of residents.

Option A is correct because it gives two valid reasons why a low-density area may need special attention. Options B, C, and D do not describe useful planning conditions: being absent from a map, having no land, or being difficult to count does not make an area nationally important. Thus low population density should never be treated as proof of low priority.

Correct answer: B. In the area with fewer water sources

The direct answer is B: pressure will be felt more in the area with fewer water sources. The two areas have the same population density, so the number of people compared with land area is equal. However, living conditions also depend on resources. If one area has very little water, each person has less water available and competition for water becomes greater. Option A is wrong because more water sources generally provide better support and reduce water-related pressure, although good management is still necessary. Option B is correct because scarce water combined with the same number of people per area creates greater difficulty. Option C is wrong because limited resources can create pressure; it is not true that both areas have no pressure. Option D is wrong because equal density does not mean equal resources, services, climate or living conditions. The lesson is that density must be interpreted with context. Exam cue: same density does not guarantee the same quality of life; compare resource availability too.

Correct answer: A. Fertile land employment and better connectivity

Direct answer: Option A is correct. High population density usually develops where people can live, work and travel more easily. Fertile land can support farming and food production. Employment provides income and attracts workers. Better connectivity through roads, railways and communication links makes movement and trade easier. Together, these natural and economic advantages can attract many people and produce high density. Option A is therefore the best combined explanation. Option B describes inaccessible mountains, water shortage and isolation, which normally discourage settlement. Option C gives permanent snow, few markets and few roads, also discouraging population. Option D describes a vast desert and weak settlement, where water and living opportunities are limited. These factors may produce low density, not high density. Exam cue: for high density, combine favourable physical conditions with jobs and transport.

Correct answer: B. Difficult terrain water shortage and poor connectivity

Difficult natural conditions and weak connectivity can reduce density. Exam tip: identify limiting factors.

Correct answer: B. Density will become half

With the same area if population halves density also falls. Exam tip: see direct relation between population and density.

Correct answer: A. Density will become half

The same population spreads over larger area so density decreases. Exam tip: remember inverse relation between area and density.

Correct answer: A. When jobs markets and services are developed in the area

Facilities and jobs can attract people in concentration. Exam tip: do not always treat high density as a problem.

Correct answer: A. When service capacity is lower than population demand

High density becomes a problem when services are insufficient. Exam tip: see capacity and demand together.

Correct answer: A. Because colour meaning is decided by the legend

Legend tells the correct meaning of colour classes. Exam tip: check legend first while reading maps.

Correct answer: A. Because high density can put pressure on limited resource capacity

Carrying capacity is linked with resource limits. Exam tip: understand density pressure and carrying capacity together.

Correct answer: A. Pressure on land and increase of small holdings

When more people depend on limited farmland land pressure rises. Exam tip: understand land man pressure.

Correct answer: A. Housing transport water and worker services

Industrial areas increase jobs as well as population pressure. Exam tip: connect industry with service planning.

Correct answer: A. Local concentration is influenced by accessibility

Road connectivity can attract population locally. Exam tip: keep average and local density separate.

Correct answer: A. When the area has fragile mountain forest or desert ecology

Low population areas can also be ecologically sensitive. Exam tip: keep density and ecological sensitivity separate.

Correct answer: A. Health and environmental pressure

Weak waste management in dense areas increases health risks. Exam tip: connect urban density with sanitation.

Correct answer: A. Because density also depends on area

When area changes people per area value changes. Exam tip: include boundary and area in density.

Correct answer: A. For quality of life environment and disaster safety

In dense areas open spaces are important for health and safety. Exam tip: link density planning with quality of life.

Correct answer: A. Because valleys may be relatively level and serviced

Valleys can become local settlement centres in hilly areas. Exam tip: understand relief and local density together.
