 The vertical imaginary lines from the North Pole to the South Pole are
called meridians. The Greenwich meridian is the 0º one.
 The horizontal imaginary lines from around the globe are called
paralells. Parallel 0º is the Equator.
 Longitude is measured by meridians and latitude by parallels. We use
degrees to measure.

The layer which has almost no
gases. There are satellites, and it´s
