2 Section A Total Marks: 30 Q1 Fill in the blanks. [ /5] a) Shifting cultivators have temporary settlements. b) Insulated ceilings minimize weather effects which reduce electricity bill. c) A transportation of goods via air route is the quickest but expensive. d) Nuclear energy is a non-renewable / unsustainable type of energy source. e) The industries that produce goods for sale are called manufacturing industries. Q2 Choose the best answer write in the space provided. [ /5] a. ii. iii. iv. i. The Rabi crops are grown in. April September January June October March b. Which of the following trees are found in the tropical rainforest? i. Bamboo tree ii. Pine iii. Coniferous c. The main source of power in Pakistan is. i. Nuclear ii. Thermal iii. Hydel d. The process of separating the grain from the plant is called. i. Fertilizing ii. Harvesting iii. Threshing e. The Masai tribes live in. i. America ii. Malaysia iii. Kenya Q3. Give reasons for the following statements. [ /5] a. Solar energy is a renewable energy source. Solar energy is a renewable energy source because it is obtained through Sun. Solar energy is the kind of energy that will not finish off if used. b. Dams are constructed to generate hydro power. Dams have been built on a height and have gates that monitor the flow of water. To generate hydro power we need fast water flow over turbines that would be installed at the dams base. c. Wind turbines are not friendly to birds. _The large propelling fans may hit the birds and kill them d. Our major agricultural produce is obtained from the Indus plains. The City School/ PAF Chapter/ Comprehensive Worksheet/ May 2018/ Geography / Class 6 Page 2 of 6

3 The Indus plain has the most agriculture as it has the rivers flowing across it the area has a reasonably favorable climate for plant growth. Also the presence of river in the area has made the land fertile. e. The Yannomammi s have to move and settle in some other areas after some years. They have to move after sometime as the soil in the area becomes poor and the crop yield declines. Q4. Identify the type by looking at the pattern of settlement. [03] Nucleated Linear Dispersed/ scattered Bu Buildings Settlement shape Q5. Look at the cartoon below about the power crisis in Pakistan and briefly suggest a solution to the problem that has been shown here. [ /2] The economy of a country is badly affected if we face power crisis. The fluctuation of oil prices in the market has led to inflation. To overcome inflation and power crisis we must start using sustainable / renewable energy sources which have a one time high installation cost but the energy they use up to work is free of cost (wind, water or sun). To uplift the economy we must put an end to power crisis. The City School/ PAF Chapter/ Comprehensive Worksheet/ May 2018/ Geography / Class 6 Page 3 of 6

4 Q6. Using the clues below identify the type of vegetation, also tell which plants / trees grow in the vegetation. [ /6] Clues Vegetation Type Plants / Trees Conifer Forest Fir, Pine or Spruce Forms a dark green carpet. Has trees that have tough needles. Trees have short and flexible branches. Temperature remains below freezing point 9 months of the year. Plants here are small and grow close to the ground. Vegetation can survive under the snow. Tundra/ Cold desert vegetation Mosses, lichens Has a hot and wet and hot and dry climate. Has trees with flat tops. Turns into a semi-desert. Tropical grassland Acacia tree, Baobab tree, Elephant Grass Q7. With the help of the source given below, explain the importance of an infrastructure for trade and economic growth. [ /4] Infrastructure has a direct relation with economic growth. It gives a technical support to our economy. Infrastructure ensures the smooth flow of services and goods. Because of infrastructure we can travel, trade and use transport and a country can prosper. The City School/ PAF Chapter/ Comprehensive Worksheet/ May 2018/ Geography / Class 6 Page 4 of 6

5 Section B Total Marks: 20 Q1 a. What are the reasons for cutting down trees? [ /2] Population Growth, Increasing farming land, Using stems to obtain wood for various purposes, making buildings, ports roads, highways etc Q1 b. What are the effects of deforestation on the environment? [ /3] Weathering and erosion of soil, Habitat of wildlife disturbed as a result wildlife gets vulnerable Less rain Landslides and earthquakes may occur/ vulnerable to natural disasters Environmental beauty gets affected Q2.Differentiate between the following. [ /6] Urban Settlement An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas cities and town. Rural Settlement A rural settlement tends to have small population. A rural settlement is a community involved in primary activities such as farming, lumbering and mining. Subsistence Farming The small scale farming that is done for the family s needs. Primitive methods of cultivation used. Done manually with less resources. Cash Crop Farming Large scale farming that is done for the purpose of earning profit/ selling. Modern methods and machinery used. Have better resources. Renewable Resources Resources that can be reused or replaced if used. Eg. Solar energy, wind power Non- Renewable Resources Resources that cannot be reused or replaced once used up. Eg. Coal, Fossil Fuels, oil, gas Q3. Singapore uses hi-tech methods to meet the food requirements in their country. [ /6] a. Identify the type of method b. Define each type c. Give a reason for using hi-tech method. The City School/ PAF Chapter/ Comprehensive Worksheet/ May 2018/ Geography / Class 6 Page 5 of 6

6 Type: Aeroponics Define:Growing vegetation without soil, but the roots are suspended and sprayed with water and/or nutrient solution. Type: Hydroponics Define:plants grown with their roots suspended directly into water which is enriched with nurients. Singapore practices soilless cultivation because it has less land and more population which leaves no space for agriculture. Q4. Define the following terms. [ /03] I. Nomadic herding Nomadic pastoralism is a form herding when livestock are herd in order to find fresh pastures on which to graze.nomadic herders move their livestock around in order to provide them with fresh food, like grass.
