1. Basic Skills
1.2 Geographic Grid
Navigate the World with the Geographic Grid System
Discover how latitude, longitude, and coordinates work together to locate any point on Earth with precision.
What You'll Learn
Latitude and longitude lines intersect to create precise Earth coordinates.
The equator and prime meridian serve as key reference baseline lines.
Each degree of latitude equals approximately sixty-nine miles on Earth.
Grid coordinates are applied in navigation, research, and digital mapping.
What You'll Practice
1
Students interpret latitude and longitude coordinates across real-world scenarios.
2
Learners identify reference lines including the equator and prime meridian.
3
Practice questions test distance calculation using geographic degree measurements.
Why This Matters
Mastering the geographic grid system equips students with the foundational coordinate skills needed for navigation, GIS technology, and all advanced geographic analysis.
