Hey GODS, good to see you again. Here are the solutions to the questions: a) i) State two evidence to justify the shape of the Earth 1. Circumnavigation of the Earth: Travelers can continuously travel in one direction and return to their starting point. 2. Ships appearing mast first: When a ship approaches from the horizon, its mast is visible before its hull, indicating the curvature of the Earth. 3. Lunar eclipse shadow: The shadow cast by the Earth on the Moon during a lunar eclipse is always circular. 4. Satellite images: Photographs taken from space clearly show the Earth as a sphere. a) ii) Define and state two characteristics of longitude lines Longitude lines are imaginary lines that run from the North Pole to the South Pole, measuring distance east or west of the Prime Meridian. Characteristics: 1. They are all semi-circles of equal length. 2. They converge at the poles. 3. They are used to determine local time. b) i) What will be the local time in an area 150° E and 5° N when GMT is 10:00 am? Step 1: Calculate the time difference. The Earth rotates 360^ in 24 hours. This means 15^ of longitude corresponds to 1 hour of time difference (360^ / 24 hours = 15^/hour). Alternatively, 1^ of longitude corresponds to 4 minutes (60 minutes / 15^ = 4 minutes/^). Step 2: Determine the total time difference for 150^ E. Time difference = 150^ × 4 minutes/^ = 600 minutes Time difference in hours = 600 minutes60 minutes/hour = 10 hours Step 3: Calculate the local time. Since the location is 150^ E (East of Greenwich), the time will be ahead of GMT. Local time = GMT + Time difference Local time = 10:00 am + 10 hours = 8:00 pm The latitude 5^ N does not affect the time calculation. The local time will be 8:00 pm. b) ii) Briefly describe how any one type of rainfall is formed Convectional Rainfall: This type of rainfall occurs when the sun heats the ground, causing the air above it to warm and become less dense. The warm, moist air rises, expands, and cools as it ascends. As the air cools, the water vapor condenses to form cumulus clouds, eventually leading to heavy rainfall, often accompanied by thunderstorms. c) Name the four main Pressure belts on the Earth surface 1. Equatorial Low Pressure Belt 2. Subtropical High Pressure Belts 3. Subpolar Low Pressure Belts 4. Polar High Pressure Belts d) i) State two causes of water scarcity 1. Climate change: Leading to prolonged droughts, reduced rainfall, and increased evaporation rates. 2. Population growth: Increasing demand for water for domestic, agricultural, and industrial uses beyond available supply. 3. Water pollution: Contamination of freshwater sources by industrial waste, sewage, and agricultural runoff, making water unusable. d) ii) For any two of the following phenomena, describe two strategies each that could be adopted to mitigate the effects: I will choose Flooding and Global warming. Flooding Mitigation Strategies: 1. Construction of dams and reservoirs: These structures help control river flow, store excess water during heavy rainfall, and release it gradually. 2. Building flood barriers: Levees, embankments, and floodwalls can be constructed along riverbanks to prevent water from overflowing into populated areas. Global Warming Mitigation Strategies: 1. Transition to renewable energy: Shifting from fossil fuels to sources like solar, wind, and hydroelectric power reduces greenhouse gas emissions. 2. Afforestation and reforestation: Planting new trees and restoring forests helps absorb carbon dioxide from the atmosphere, acting as carbon sinks. Send me the next one 📸
