Understanding Longitude and Latitude
Before diving into worksheets, it’s essential to understand the fundamental concepts of longitude and latitude, which form the backbone of geographical navigation and map reading.
What is Latitude?
Latitude lines run parallel to the Equator, which is the 0° latitude line dividing the Earth into the Northern and Southern Hemispheres. These lines measure the distance north or south of the Equator in degrees, ranging from 0° at the Equator to 90° at the poles (North Pole at 90°N and South Pole at 90°S). Latitude is crucial in determining how far north or south a location is from the Equator.
What is Longitude?
Longitude lines run from the North Pole to the South Pole, converging at the poles and crossing the Equator at right angles. These lines measure the distance east or west of the Prime Meridian, which is at 0° longitude and runs through Greenwich, England. Longitude is expressed in degrees from 0° to 180°, east or west of the Prime Meridian.
Coordinate Format
Coordinates are typically written in degrees, minutes, and seconds (D° M' S'') or in decimal degrees (e.g., 34.0522° N, 118.2437° W). For worksheets, the most common format is degrees and directions (N, S, E, W).

Answer Key
Part 1: Multiple Choice
1. a) 0° longitude
2. c) 30° N, 60° W
3. c) Southern and Eastern
4. b) Equator and East of Prime Meridian
Part 2: Coordinate Plotting
a) Point C (0°, 0°) is closest to the Equator since it lies exactly on it.
b) Point B (35° S, 138° E) is in the Southern Hemisphere.
c) Points B, C, and D are in the Eastern Hemisphere; Point A is in the Western Hemisphere.
Part 3: Conversion Exercises
1. 23° N, 45° W
- 23° N = 23.0000°
- 45° W = -45.0000° (since West is negative)
2. 60° S, 90° E
- 60° S = -60.0000°
- 90° E = 90.0000°
3. 15° N, 120° E
- 15° N = 15.0000°
- 120° E = 120.0000°
Part 4: Short Answer
1. The Prime Meridian is the zero-degree longitude line that divides the Earth into the Eastern and Western Hemispheres. It serves as the starting point for measuring longitude and is essential for navigation, mapmaking, and global timekeeping (Greenwich Mean Time).
2. To locate a city, you need its exact latitude and longitude coordinates. By plotting these on a map or globe, you can pinpoint the city’s precise position on the Earth's surface.
3. Understanding coordinate systems is crucial for navigation, cartography, disaster response, travel planning, and geographic information systems (GIS). It allows for accurate location identification and spatial analysis.
