Understanding Latitude and Longitude

The video tutorial explains the concepts of latitude and longitude, emphasizing their imaginary nature and usage on maps and globes. It details how longitude lines run north-south and latitude lines run east-west, with the prime meridian and equator as reference points. The tutorial also covers how to pinpoint locations using degrees, minutes, and seconds, providing examples like Washington DC. It concludes with a mention of GPS technology for determining precise coordinates.

What are latitude and longitude lines primarily used for?

How many minute lines are there between each degree of latitude and longitude?

• 45

• 30

• 60

• 90

What does GPS stand for?

• Geographic Positioning Service
