This makes it among the world's most climate change-vulnerable nations.

The 30 flattest countries in the world

How do these flat countries level up?

23 hours ago | StarsInsider

TRAVEL Topography

By measuring the elevation distance—or elevation span—between a country's highest and lowest points, it's possible to average out how flat that country's terrain is.

Countries with low topographic relief are considered flatter because there's little variation in elevation.

But while some nations have consistently flat terrain, other countries have lower minimum elevations at some points. It's these variables that make this gallery so fascinating. It includes countries you might never have expected to be included in a list such as this!

Sadly, though, some of the lowest-lying nations are particularly susceptible to climate change-induced rising sea levels and coastal erosion.

By referencing World Atlas and World Population Review, we've ranked the 30 countries with the lowest average elevations worldwide. Click through and find out how they level up.
