Population Size and Distribution

Correct answer: C. No, a large area can also have low population

A large area does not always mean a large population. Exam tip: view area and population separately.

Correct answer: D. When many people live in a small area

Density is high when many people live in a small area. Exam tip: look at the balance of area and population.

Correct answer: A. Availability of jobs and services

The direct answer is Option A: availability of jobs and services is a major reason for high urban population. Cities usually provide more factories, offices, shops, schools, colleges, hospitals, transport links and other services than many rural areas. These opportunities attract people from villages and smaller settlements, a movement called migration. Cities can therefore grow through both natural population increase and in-migration. Option A is correct because employment and services create a strong urban pull. Option B is wrong because constant snowfall is not a general feature of cities and would often discourage settlement. Option C is wrong because some cities have farming around them, and the absence of farming is not the main reason for urban population. Option D is wrong because drying of the sea is unrelated to ordinary urban population concentration. Remember: jobs, education, health care and facilities are common urban pull factors.

Correct answer: B. Agriculture

Agriculture is a major economic activity in rural life. Exam tip: connect rural population with farming.

Correct answer: C. Dense forest and inaccessible area

Dense forests and inaccessible areas can make settlement difficult. Exam tip: consider access and facilities as reasons.

Correct answer: D. Areas where more or fewer people live

A distribution map shows regional differences in population. Exam tip: identify dense and sparse areas while reading maps.

Correct answer: A. Water

High population increases demand for drinking and usable water. Exam tip: write resource pressure with examples.

Correct answer: B. Physical and human factors

Both physical and human factors affect distribution. Exam tip: writing both types of reasons is better.

Correct answer: A. Water and fertile soil are available there

River valleys support farming and settlement. Exam tip: treat river valleys as a reason for high density.

Correct answer: B. Persons per square kilometre

Population density is expressed as persons per square kilometre. Exam tip: always write the unit.

Correct answer: A. Population size

Population size means the total number of people living in a particular area at a particular time. It is a simple count, such as the number of people in a village, city, state, or country. Population density is different: it compares the number of people with the area of land, commonly expressed as people per square kilometre. Population distribution describes where people are located. Keeping these terms separate prevents confusion.

Option A is correct because “population size” directly refers to the total population. Soil erosion is the removal of soil, vegetation type describes plant cover, and a rain shadow is a dry area formed on the leeward side of a mountain. None of these terms measures the number of people. The key word is “total,” which indicates a count rather than a ratio, location pattern, or natural process.

Correct answer: B. Population distribution

The direct answer is B: population distribution. Population distribution means how people are spread across different places or regions. Step by step: look at a map or area → observe where people live in large or small numbers → describe the spatial pattern → this is population distribution. Option B is correct because it directly names regional spread. Option A, population growth, means an increase or decrease in population over time, usually through births, deaths, and migration; it does not mainly describe where people are located. Option C, sex ratio, compares the number of females and males, commonly expressed per 1,000 males; it describes composition, not location. Option D, literacy rate, gives the share of people who can read and write according to a stated definition; it describes an educational characteristic, not spatial spread. A distribution map can show dense, moderate, and sparse areas. Memory cue: distribution answers “where?”, while growth answers “how does the number change?”.

Correct answer: C. Attraction of people may increase

Facilities such as schools, hospitals, transport, markets, electricity, and communication make daily life easier. They can also provide better opportunities for education, health care, business, and employment. As a result, people may choose to move to or settle in places with more facilities. This is a human factor in population distribution, and its effect is usually an increase in the area’s attraction, although it does not guarantee that every person will move there.

Option C is correct because improved facilities can increase the attraction of a place and encourage settlement or migration toward it. Option A is an extreme and unreasonable claim: facilities do not make population zero. Option B is the opposite of the likely effect, while D has no connection with population geography. The wording “may increase” is appropriate because population response depends on other conditions too.

Correct answer: D. Inaccessible mountainous area

In inaccessible mountainous areas, access and transport are difficult. Exam tip: connect transport with population distribution.

Correct answer: A. The Ganga plain is highly populated

The Ganga plain is densely populated due to fertile land and water. Exam tip: remember it as a standard example.

Correct answer: B. Due to work opportunities

Industrial areas provide employment. Exam tip: write employment as a reason for population attraction.

Correct answer: A. Fertile plain

Fertile plains are suitable for farming and increase settlement. Exam tip: write fertile soil as a key reason.

Correct answer: C. Industry

Industry is a human and economic factor that can attract people. Exam tip: connect industry with employment.

Correct answer: D. Climate

Climate is a physical factor that affects settlement. Exam tip: write climate, relief and water as physical factors.

Correct answer: A. Sparsely populated area

An area with low population is called sparsely populated. Exam tip: remember the difference between sparse and dense.

Correct answer: B. Densely populated area

The direct answer is B: densely populated area. Population density describes how many people live in a unit of land area. If many people live in a relatively small or stated area, the area is called densely populated. The reasoning is: observe a high number of people → compare it with the available area → classify the place as dense or high-density. Option A, sparse area, means few people are spread over a large area, so it is the opposite. Option B is correct because it directly means an area with a high concentration of people. Option C, uninhabited area, means no people live there, so it cannot describe a high-population place. Option D, empty plateau, describes neither population concentration nor a general population term; a plateau may be densely or sparsely populated depending on conditions. Do not confuse population size with density: a large total population can occupy a very large area, while density depends on people in relation to area. Memory cue: many people in limited space means dense.

Correct answer: A. Total number of people

Population size is compared by total number of people. Exam tip: do not confuse size with area.

Correct answer: A. Number and distribution of population

Population number and distribution help plan facilities. Exam tip: remember the uses of population data.

Correct answer: A. Where more and fewer people live in a country

Population distribution shows the spread of high and low population areas. Exam tip: it is easier to understand on a map.

Correct answer: C. Trade and employment opportunities

Ports increase trade and employment so people may settle there. Exam tip: treat transport and trade as human factors.
