Answer:
A rift valley is formed from a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepended by the forces of erosion.
The Pyrenees are a mountain range in the western part of Europe. This mountain range is a natural boundary between the Iberian Peninsula and the rest of Western Europe.
This mountain range has formed as part of the Alpine orogenesis. The Alpine orogenesis has been triggered by the movement of Africa toward Europe, so the pressure created between the African and Eurasian tectonic plates has managed to lift up the land and create mountains, including the Pyrenees.
The Pyrenees are considered as young mountain range, and their formation is still not ended, but instead they are still growing in size and elevation.
These mountains make up the border between the nations of Spain, on the south from them, and France, on the north of them. There is one very small nations located on the mountains themselves, that being Andorra.
