The image displays two different ways to map the surface of the Earth using a grid system.
Left Diagram (Latitude):
* This view shows the Earth from the side.
* The lines run horizontally (east to west). These are called
parallels of latitude.
* The center line is the
Equator at $0^\circ$.
* Lines above the Equator go up to $90^\circ\text{N}$ (North Pole).
* Lines below the Equator go down to $90^\circ\text{S}$ (South Pole).
* This system measures how far north or south a location is.
Right Diagram (Longitude):
* This view shows the Earth looking down towards the North Pole.
* The lines run vertically from pole to pole. These are called
meridians of longitude.
* The starting line is the
Prime Meridian at $0^\circ$ (running through Greenwich, London).
* Lines to the right are East ($E$) and go up to $180^\circ$.
* Lines to the left are West ($O$ or $W$) and go up to $180^\circ$.
* This system measures how far east or west a location is.
Together, latitude and longitude create a coordinate system that allows us to pinpoint any exact location on Earth.
Final Answer:
The image illustrates the global grid system used for mapping Earth:
1.
Latitude (left): Horizontal lines measuring distance North ($N$) or South ($S$) from the Equator ($0^\circ$).
2.
Longitude (right): Vertical lines measuring distance East ($E$) or West ($O/W$) from the Prime Meridian ($0^\circ$).
Parent Tip: Review the logic above to help your child master the concept of longitude vs latitude difference.
