REPRESENTATIONS OF THE EARTH



SOCIAL STUDIES, TOPIC 1.
REPRESENTATIONS OF THE EARTH

Earth Globes

A Globe is a sphere that represents the planet Earth. In it we can see imaginary lines that represent:

  • Equator: imaginary line that divides the Earth in two halves.
  • Poles: North and South. They are in opposite extremes of the central axis.
  • Central axis: imaginary line from North Pole to South Pole.
  •  

Cartography and maps

Cartography is the science of making maps. Maps are pictures of places. So as to make a map we follow the next steps:
1)     Collecting data: artificial satellites give us different data from the Earth.
2)     Making the map: use of the data so as to draw the map.

Types of maps:

 

a)     Physical: geography (mountains, rivers…



b)     Political: countries, states, Autonomous Communities…


c)     Theme maps: depending on the topic (climate, population, history of migrations…).

 

Maps

A map uses different elements to give information:
