In this lesson, we look at what a population pyramid is, how to read it, some interesting features about them, and what are some prototypical examples of them.

Geography Tools: Photographs, Globes & Diagrams

8. Geography Tools: Photographs, Globes & Diagrams

This lesson takes a peek into the geographer's toolkit to examine how they use photographs, globes, and diagrams to study our planet. This includes both aerial and satellite photographs, virtual globes, and diagrams we see every day.

Atlases & Almanacs as Sources of Geographic Information

9. Atlases & Almanacs as Sources of Geographic Information

Just like any other profession, geographers have specialized tools to help them. While they also rely on technologies like satellite imagery and advanced surveying tools, many geographers also use almanacs and atlases in their daily work.
