Question 1005

[2 marks]Environmental restoration, environmental aspects and land use planning
Which part of the environment supplies the oxygen animals breathe and carries the water vapour that becomes rain?
  1. Athe hydrosphere
  2. Bthe biosphere
  3. Cthe atmosphere
  4. Dthe lithosphere

Question 1006

[2 marks]Environmental restoration, environmental aspects and land use planning
The hydrosphere is important to a community because it

  2. Bfilters out the harmful ultra violet radiation from the sun
  3. Csupplies the timber and the thatching grass used in building
  4. Dsupplies drinking water and irrigation, and is a habitat for fish

Question 1007

[2 marks]Environmental restoration, environmental aspects and land use planning

[2 marks]Environmental restoration, environmental aspects and land use planning

  2. Bzones fragile wetlands and stream banks out of cultivation and settlement
  3. Cincreases the total area of the arable land that is available to a district
  4. Dremoves the need to carry out an environmental impact assessment

Question 1009

[2 marks]Environmental restoration, environmental aspects and land use planning
Land use planning often fails to protect an urban wetland in practice because
  1. Ano law anywhere allows a council to zone its own land for any particular use
  2. Bwetlands are too small to appear on a land use plan in the first place
  3. Cplanners always place the housing on the wettest land that is available

Question 1105

[2 marks]Population terms, population pyramids and malaria
A population pyramid with a very broad base and rapidly narrowing sides shows a country with
  1. Aa low birth rate and a long life expectancy
  2. Bmore men than women in every single age group
  3. Can ageing population and very few young children
  4. Da high birth rate and a short life expectancy

Question 1106

[2 marks]Population terms, population pyramids and malaria
A country whose population pyramid has a very wide base carries a high dependency ratio because
  1. Aevery adult in the country is already employed in the formal sector of work
  2. Bthe crude birth rate and the crude death rate are exactly equal to each other
  3. Ca large number of children must be supported by a smaller working population
  4. Dthe elderly outnumber the working population in every province of the country

Question 1107

[2 marks]Population terms, population pyramids and malaria

  1. Abuilding more maternity wards at each one of the district hospitals
  2. Braising the rate of tax charged on imported tinned baby food
  3. Cincreasing the number of clinics operating in the capital city
  4. Dkeeping girls in school for longer and raising the age of marriage

Question 1108

[2 marks]Population terms, population pyramids and malaria
Eradicating malaria in Zimbabwe is difficult mainly because
  1. Athe mosquito that carries the parasite is found only inside the cities
  2. Bmalaria cannot be diagnosed without sending samples out of the country
  3. Clarge low-lying areas stay hot and wet enough for the mosquito to breed
  4. Dno drug exists that is able to treat a case of malaria once it develops

Question 1109

[2 marks]Population terms, population pyramids and malaria
Treated mosquito nets fail to control malaria in some districts because
  1. Ahouseholds use them for fishing or for fencing instead of sleeping under them
  2. Bthe nets attract more mosquitoes into the house during the course of the night
  3. Cthe insecticide used to treat the nets is harmful to very young children
  4. Dthe mosquitoes in those districts bite only during the hours of daylight

  3. Cit reduces the amount of the mineral that has to be mined in the first place
  4. Dit removes the need to employ any labour at all at the mine site itself

  4. Dnumbers fell until 2018 and then recovered slightly by the year 2020

Question 1206

[2 marks]Balance of payments, beneficiation and rail transport
The main reason rail passenger numbers fell so far is that
  1. Athe fares charged were far higher than any bus fare on the route
  2. Bno town in the country is served by a railway line any longer
  3. Cworn track and old coaches made the service slow and unreliable
  4. Dthe government banned all passenger trains on the main lines

Question 1207

[2 marks]Balance of payments, beneficiation and rail transport

  3. Ccharge no fare at all on the routes where the railway also runs
