Here's why:

* Flat Terrain: Tundra regions are known for their flat, often rolling landscapes.

* Little Vegetation: Due to the harsh climate, tundra ecosystems support limited plant life, typically low-growing shrubs, grasses, mosses, and lichens.

* Constantly Frozen Subsurface: The defining feature of tundra is permafrost, a layer of soil that remains permanently frozen for at least two years.
