Question 1.
Trace the journey of your shirt from a cotton field to your wardrobe.
Answer:
Cotton yam that is used in making cotton garments have to go through a long journey from fields to our wardrobes. The first step is naturally growing cotton in the fields which takes a long time and lot of efforts. Cotton is found in small bud like structures. During harvesting season, farmers pluck out cotton buds and separate raw cotton. The raw cotton is then spinned on a hand loom or power loom. After spinning, cotton yam is weaved to make finished cotton cloth. This cloth is used by tailors to make different garments and sold to retailers. We buy garments from retailers and that is how it reaches us.

Question 5.
Activity
How to identify a location for establishing an industry :
Divide your class into groups. Each group is a Board of Directors faced with the problem of choosing a suitable site for an iron and steel plant of Developed Dweep. A team of technical experts has submitted a report with notes and a map. The team considered access to iron ore, coal, water and limestone, as well as the main market, sources of labour and port facilities. The team has suggested two sites, X and Y. The Board of Directors has to take the final decision about where to locate the steel plant.

  • Read the report submitted by the team.
  • Study the map to find out the distances of the resources from each site.
  • Give each resource a ‘weight’ from 1 to 10, according to its importance. The greater the ‘pull’ of the factor on the industry the higher the weight from 1 to 10.
  • Complete the table on the next page.
  • The site with the lowest total should be the most satisfactory site.
  • Remember each group of directors can decide differently.

JAC Class 8 Social Science Solutions Geography Chapter 5 Industries 1
Report Factors/Resources affecting the location of a proposed Iron and Steel Plant on Developed Dweep.

  • Iron ore:
    This is a very large deposit of low grade iron ore. Long distance transportation of the ore would be uneconomic.
  • Coal:
    The only coalfield contains rich deposits of high grade coal. Transportation of the coal is by railway, which is relatively cheap.
  • Limestone:
    This is widely available over the island, but the purest deposits are in the Chuna Mountains.
  • Water:
    Both the tributaries of River Neel carry sufficient water to supply a large iron and steel plant in all seasons. The sea water because of its high salt content is unsuitable.
  • Market:
    It is expected that the chief market for the Plant’s products will be the engineering works of Rajdhanipur. Transport costs for the products-mainly small steel bars and light steel plates would be relatively low.
  • Labour supply:
    This will have to be recruited mainly from the unskilled workers in the 3 fishing villages of Hill, Rah and
    Sing. It is expected that most workers will commute daily from their present homes.
  • Port facilities:
    These are at present minimal. There is a good, deep natural harbour at port Paschimpur developed to import metal alloys.
