🌍 How Do We Map Our World?

 

🧭 Why Do We Use Maps?

People have used maps for thousands of years to:

• Travel and find places
• Explore new lands
• Understand the world around them

Maps help us show many things like countries, land features, and distances.

⚠️ Are Maps Always Correct?

No map is perfectly correct.

• The Earth is round (a sphere)
• Maps are flat (2D)
• So, when we draw maps, some parts become stretched or distorted

These ways of drawing maps are called projections.
