F. Answer the following questions in one or two paragraphs.

Question 1.
What are the different factors that determine the location and the type of settlements?
Many factors determine the location and the type of settlements:

  1. Settlements grow in areas that are flat and where the land is cultivable. Settlements do not grow on steep hillsides or marshy lands.
  2. Settlements grow in places where water is available in plenty for both agricultural and domestic purposes. Settlements, therefore, also grow on the confluence of rivers or the banks of rivers.
  3. Settlements also thrive on a plateau because of the flat surface of the plateau and the availability of land for cultivation.
  4. They develop and grow in places where the climate is- suitable or pleasant to live in. Extremely hot, cold, wet or dry places are not attractive settlement sites.
  5. Settlements are formed where there are prospects for employment. Mines and industries in the area are potential sources of employment and encourage growth of settlements. Such places are usually near places of abundant raw materials for the growth of industries.
  6. They develop in places that are easily accessible by various kinds of roads, rivers, and railway lines. Easy access to and from the settlements will allow movement of people and goods from one place to another.

Question 2.
What are the causes of brain drain ?
Causes of Brain Drain :

  • Push factors — They include economic factors such as the inability to find suitably paying jobs in a person’s own country, poverty or no prospect of improving one’s standard of living, political instability that causes uncertainity, political favouritism, and religious and social discrimination.
  • Pull factors — They include higher income and more comfortable lifestyles in the new country, better economic prospects, better educational opportunities including training and research, greater chances of promotion without partiality or discrimination, a liberal and stable government, better working conditions and medical facilities.

Question 3.
What makes Bihar the most flood-prone state among all north Indian states ?
Bihar is the most flood-prone state among all north Indian states because many of the rivers flowing through Bihar, such as the Kosi, Bagmati and Gandak, flow through the high mountainous region of Nepal, before crossing very small distances and rapidly reaching the plains of Bihar, making them far more forceful. When it rains heavily in Nepal, the extra water enters these river channels and rushes into the plains of Bihar. As the rivers break their banks and overflow into the adjoining areas, large area of land and thousands of people and livestock are affected. More than 76% of the population in Northern Bihar live under the threat of floods
every year.

Question 4.
Explain the different types of migrations.
There are different types of migration :

  1. Internal migration—People move from one place to another within the country.
  2. External migration — People move to a new country or continent.
  3. Temporary migration — It includes migration which is annual, seasonal or daily. For example, people may move to lower regions from mountains during harsh winter months.
  4. Emigration — When a person leaves his or her own country and moves to another. The person who emigrates is known as an emigrant from his or her own country. For example, when a person leaves India and goes to Canada to settle there, that person is said to have emigrated from India to Canada.
  5. Immigration — When a person arrives in a new country after leaving his or her own country. For example, when a person arrives in Canada from India that person is said to have immigrated to Canada and is known as an immigrant in Canada.

Question 5.

Impace of Under population

Under population has several positive effects :

  1. There are sufficient employment opportunities for everyone.
  2. There are fewer instances of overcrowding.

  4. There are adequate educational, medical and other facilities to meet everyone’s needs.
  5. There are sufficient natural resources to meet the requirements of the population.
  6. There is lesser pressure on the environment, and hence, lower rates of environmental degradation.

However, there are also some negative effects of under population :

  1. The lack of adequate labour leads to low productivity.
  2. In some instances, a higher proportion of the population is either too young or too old to work.
  3. There are lesser taxpayers, leading to low income for the government.
  4. There are not enough people to develop the natural resources of the country.
