π Understanding Map Keys
A map key, also known as a legend, is like a decoder for maps. It explains what the symbols, colors, and lines on a map represent. Without a map key, it would be difficult to understand what anything on the map means!
π The History of Map Keys
People have been making maps for thousands of years! Early maps often used simple drawings to represent features like mountains and rivers. As maps became more detailed, map keys were developed to help people understand all the different symbols. Over time, the symbols used in map keys have become more standardized, making it easier for people to read maps from different places and times.
