Oct/Nov 2021 Flashcards
describe the location of the Sulaiman Range
- East of Quetta
- West of river Indus
- Near to river Zhob
- In the Centre of Pakistan
Two features of the Salt Range
- dry
- sandy
Two minerals that can be obtained from the Salt Range and
suggest one use for each.
- mineral: salt/halite
- use: for cooking
Explain two ways in which the natural topography of the Salt Range
makes mineral exploitation difficult. You should develop your answer.
- Steep slopes – so it is difficult to get (large) machinery into the area
- Barren land – difficult to construct roads
Describe three environmental problems caused by mineral extraction
- Air pollution from machinery
- noise pollution from machinery
- landslides due to explosions
Evaluate the benefits and problems of further developing the mineral extraction industry in Pakistan. Give reasons to support your judgment and refer to examples you have studied. You should consider different points of view in your answer.
Benefits:
- loans for equipment/hiring experts from abroad with technical expertise
- sustainable mining techniques reduce environmental damage
- e.g. In 2014, the Chinese company MCC took over the operation of the Duddar
lead/zinc mine in Balochistan. Production increased rapidly as MCC brought
in experts and modern mining machinery.
PROBLEMS:
- environmental damage can be irreversible
- jobs may be low-paid and dangerous
Describe how the Western Depressions affect the pattern of rainfall in western Pakistan
- Western Depression brings rain to the north-western areas of Pakistan
- Western Depression causes the rainfall from December-March
- Quetta dry for rest of year
Explain two factors that affect the temperature in Pakistan. You should develop your answer
- latitude; areas closer to the equator or southern Pakistan have
higher temperatures as the sun’s rays are more concentrated - deforestation; areas with dense cover have lower temperatures since it provides shade from the sun’s rays
Define ‘drought’
A long period of no rainfall.
State two effects of drought on the natural environment of Pakistan.
- plants die
- soil erosion
Describe the benefits and problems of cold climates for people in Pakistan
benefits:
- frozen water bodies can be used for ice skating
- lower need for/cost of air conditioning
problems:
- snow/cold can trap people in homes
- roads can become blocked by snow
View A
Storms and heavy rainfall have the most severe impacts on people in
Pakistan.
View B
Droughts have the most severe impacts on people in Pakistan.
Which view do you agree with more?
Give reasons to support your answer and refer to examples you have studied. You should consider View A and View B in your answer.
Agree with View A:
- storms and heavy rainfall can destroy crops very quickly
- businesses can be washed away
Disagree with View A:
- flood protection schemes can protect homes and businesses.
Agree with View B:
- droughts can cause starvation/famine leading to illness and death
- results in crop failure and death of livestock
Disagree with View B:
- Belongings/buildings/homes are not ruined by drought.
Describe the distribution of areas with over 50% of land under
cultivation
- Uneven distribution in three areas
- Mostly in the north-east
Define ‘cultivation’
- To prepare the land and grow crops on it
State two reasons why wheat is the main crop grown in Pakistan
- the main part of the (local) diet
- rise in local demand due to increasing population
