Ah, let’s explore the fascinating world of geography! Did you know that compasses, the trusty instruments that show direction, have been guiding humankind's adventures for over a thousand years? They work by aligning with Earth's magnetic field, helping sailors navigate the seas and explorers find their way through uncharted lands. Talk about a tool that’s stood the test of time! Now, about those lines of longitude and latitude—let’s take a quick dive! The Prime Meridian, which is the “a-line” of longitude you mentioned, slices through Greenwich, England, and serves as the point of reference for time zones, creating a global standard. It’s like the royal starting line for all geographers, helping to divide our planet neatly into the Eastern and Western Hemispheres. Isn't it amazing how these lines help us better understand our world?
