What is a Stevenson's screen and longitude? When the local time is 2.00 pm at longitude 45 E, what is the longitude of a place whose local time is 10.00 am?

Here are the answers to your questions: b) Three characteristics of a Stevenson's screen: • It is painted white to reflect solar radiation and prevent heat absorption. • It has double-louvred sides to allow free air circulation while shielding instruments from direct sunlight and precipitation. • It is made of wood, which is a poor conductor of heat, further insulating the instruments from external temperature fluctuations. 4 a) What is a longitude? Longitude is the angular distance, measured in degrees, east or west of the Prime Meridian. Lines of longitude, called meridians, run from the North Pole to the South Pole. 4 b) When the local time is 2.00 pm at longitude 45 E, what is the longitude of a place whose local time is 10.00 am? Step 1: Calculate the time difference between the two places. Time difference = 2:00 pm - 10:00 am = 4 hours Step 2: Convert the time difference into longitude difference. Since the Earth rotates 15^ in one hour: Longitude difference = 4 hours × 15^/hour = 60^ Step 3: Determine the direction of the unknown longitude. Since the local time (10:00 am) is earlier than the known time (2:00 pm), the place must be to the west of 45^ E. Step 4: Calculate the longitude of the place. Longitude = 45^ E - 60^ = -15^ A negative value indicates a longitude in the Western Hemisphere. The longitude of the place is 15° W. 5 a) What is weather forecasting? Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. It involves analyzing current weather conditions to project future weather patterns. 5 b) State three significance of weather forecasting: • Agriculture: Helps farmers decide on planting, harvesting, and irrigation schedules to optimize crop yields. • Aviation and Shipping: Provides crucial information for safe navigation, helping pilots and captains avoid dangerous weather conditions. • Disaster Preparedness: Enables early warnings for extreme weather events like floods, hurricanes, or droughts, allowing communities to prepare and minimize damage.
