• Item 1 1a) Distance between the areas=20cm scale of the map=1:50000 =(20*50000)/100000 =10 The distance by road from okpokhams to the road junction of babongidda is 10km

  1b) The bearing of lawyer’s camp from okebe 240degrees

  1c) i)farming due to presence of scattered grass ii)fishing due to presence of river iii)transportation due to the presence of roads network iv)trading due to the presense of market

  3a) Temperature is the degree of hotness or coldness of a body or an object. it is measured with thermometer

  3b) As height or altitudes increases,temperature decreases.hence for every 100metres of ascent,temperature decreases by 0.65 degrees celcius or 1 degrees celcius for approximately 160metres of ascent.The decrease in temperature with increasing elevation is called lapse rate

  3c) Town A: Temp=50C Height=sea level Town B: Temp=? Height=4000m above sea level Recall 1C=160m Tb=4000m (Tb*160)/160=(4000*1)/160 Tb=25C Therefore the temperature of town B is 25 degrees celcius ================ 7a) i)Volcanic eruption ii)Earthquakes iii)Tornadoes

  7b) i) Air pollution causes impaired health such as the irritation of eyes, lungs and skin cancer ii) It causes suffocation iii) It can cause accidents as a result of poor visibility
