The spectro-analyses had shown that it was outside the life zone of Betelgeuse.

Five of the 9 life zones are found in the Chiricahua Mountains.

In his famous 1947 paper, he defined "life zones" using three indicators:

It had one planet in its life zone.

Central Europe contains several life zones, depending on location and elevation.

In fact, the six life zones of the park (a rare phenomenon for such a small area) support 22 forest and 16 grass ecosystems.

Because of this, mountain ecosystems form life zones, which are stratified according to elevation.

The Upper Sonoran is a life zone between 1,000 to 3,500 feet above sea level.

A bit small, but the fourth from the star is within the carbon-based life zone.

It has many plants identical to those of the arctic, and is mostly a cold, rocky life zone.
