Study the map extract IFO DISTRICT on a scale 1:50,000 and answer the questions that follow:

Here are the answers to your questions: 4. *a) Calculate the: i) Annual temperature: The annual temperature is the average of the monthly temperatures. Sum of monthly temperatures = 27+27+28+28+28+27+27+27+27+27+26+28 = 327^ C Annual temperature = 327^ C12 = 27.25^ C ii) Mean annual rainfall: The mean annual rainfall is the sum of the monthly rainfall values. Mean annual rainfall = 178+178+180+200+250+270+240+220+260+280+190+170 = 2616 mm iii) Rainfall range: The rainfall range is the difference between the highest and lowest monthly rainfall. Highest rainfall = 280 mm (October) Lowest rainfall = 170 mm (December) Rainfall range = 280 mm - 170 mm = 110 mm b) Plot the rainfall distribution pattern of the station on bar graph. I cannot provide a diagram or plot a graph in this format. 5. a) Define Karst region. A Karst region is a landscape characterized by distinctive landforms created by the dissolution of soluble bedrock, primarily limestone, dolomite, or gypsum. These regions typically feature sinkholes, caves, underground drainage systems, and a lack of surface rivers. b) List five underground features of Karst region. • Caves • Caverns • Stalactites • Stalagmites • Pillars (columns) c) Enumerate four importance of Karst region. • Water supply: Karst aquifers are significant sources of groundwater for many populations. • Tourism: The unique landscapes, caves, and geological formations attract tourists, contributing to local economies. • Scientific research: Karst areas provide valuable sites for studying geology, hydrology, and paleontology. • Unique ecosystems: Caves host specialized and often endemic flora and fauna, contributing to biodiversity. d) List five problems of Karst region. • Groundwater contamination: Karst aquifers are highly vulnerable to pollution due to rapid infiltration and direct connections to the surface. • Sinkhole collapse: Sudden collapse of sinkholes can damage infrastructure, buildings, and endanger lives. • Unstable foundations: Building on karst terrain is risky due to unpredictable ground stability and the potential for subsidence. • Water scarcity: Rapid underground drainage can lead to a lack of surface water, making water management challenging. • Difficult waste disposal: Proper waste disposal is problematic due to the high risk of contaminating groundwater.
