The phrase that best describes the geography of Chile is "A long and narrow strip of land wedged between the Andes Mountains and the Pacific Ocean."

Here's why:

* Long and narrow: Chile is a very elongated country, stretching over 4,300 km (2,670 mi) north to south but only averaging 177 km (110 mi) east to west.

* Andes Mountains: The Andes Mountains run the entire length of Chile's eastern border, creating a dramatic and varied landscape.

* Pacific Ocean: The Pacific Ocean forms Chile's western border, giving it a coastline of over 6,400 km (4,000 mi).

This description captures the most defining features of Chile's geography.
