A Grid System Pinpoints Locations
Latitude and longitude form a global grid system that allows geographers, navigators, and travelers to pinpoint the exact location of any place on Earth using numerical coordinates. Lines of latitude run east to west parallel to the equator, while lines of longitude run north to south through the poles. Where a latitude line and longitude line intersect gives a place its absolute location, expressed as degrees north or south and degrees east or west. This Grade 5 history and geography skill from Social Studies Alive Americas Past teaches the foundational geographic tool used in navigation, mapmaking, and modern GPS technology.
Key Concepts
Imagine Earth is wrapped in invisible lines.
Lines that run east and west, parallel to the Equator, are called latitude . Lines that run north and south from pole to pole are called longitude .
Common Questions
What is latitude?
Latitude lines are imaginary horizontal lines that run east and west around the Earth, parallel to the equator. Latitude measures how far north or south a place is from the equator, expressed in degrees from 0 to 90.
What is longitude?
Longitude lines are imaginary vertical lines that run from the North Pole to the South Pole. Longitude measures how far east or west a place is from the prime meridian, expressed in degrees from 0 to 180.
What is absolute location?
Absolute location is the exact position of a place on Earth, expressed using latitude and longitude coordinates. For example, New York City is located at approximately 40 degrees North latitude and 74 degrees West longitude.
When do 5th graders learn about latitude and longitude?
Fifth graders study latitude and longitude in Grade 5 social studies as part of Chapter 1 of Social Studies Alive Americas Past, which covers Americas geographic setting and map skills.
How do latitude and longitude work together?
Together, latitude and longitude form a coordinate system like a grid over the Earth. Every location has one latitude number and one longitude number. These two numbers together identify one specific point on the planet.
How is latitude and longitude used today?
GPS navigation systems, online maps, aviation, shipping, and weather forecasting all rely on latitude and longitude coordinates. When your phone shows your exact location on a map, it is using latitude and longitude data.
