MERIDIANS

• There are infinite meridians.
• Their direction is N-S.
• They have their maximum separation in Ecuador and converge at the poles.
• They cut the parallels at right angles.
• The arc of a parallel has a value of 180 degrees.

Longitude is the distance measured in degrees, minutes and seconds, from any point on Earth's surface and the meridian 0 (Greenwich).

It is measured east or west. Its value is between 0 and 180 degrees.

PARALLELS

- They are parallel to each other. 
- Their number is infinite. 
- They have E-W direction. 
- Parallels and meridians cut each other at a right angle. 
- They form a circumference of 360 º.

Latitude is the distance expressed in degrees, minutes and seconds, between any point on Earth's surface and the parallel 0 º or Ecuador.

It is measured northward or southward. Its value is between 0 and 90 degrees.
