Globe
A true, three-dimensional miniature model of the Earth that helps us see countries, continents, and oceans in their correct shapes and relative locations.
Latitudes (Parallels)
Imaginary horizontal lines running from east to west around the Earth, with the Equator acting as the 0-degree baseline dividing the globe into Northern and Southern Hemispheres.
Longitudes (Meridians)
Imaginary vertical lines running from the North Pole to the South Pole, with the Prime Meridian passing through Greenwich, London, serving as the 0-degree starting point.
Grid System
The intersecting network formed by the crossing of latitude and longitude lines, which allows us to find the exact location of any place on Earth.
Equator
The 0-degree latitude line that divides the Earth equally into the Northern Hemisphere and the Southern Hemisphere.

Frequently Asked Questions
Why do we need imaginary lines like latitudes and longitudes?
Imaginary lines help us locate any exact place on the vast surface of the Earth easily and accurately, just like finding a seat in a movie theatre using rows and columns.
What is the difference between latitudes and longitudes?
Latitudes are horizontal lines running east-west that measure distance north or south of the Equator. Longitudes are vertical lines running north-south that measure distance east or west of the Prime Meridian.
What is the Prime Meridian and where is it located?
The Prime Meridian is the 0-degree longitude line that passes through the Royal Observatory in Greenwich, near London, UK. It divides the Earth into the Eastern and Western Hemispheres.
