Mountains don't breathe in the way living things do. They don't have lungs or any other respiratory system. Here's why that question doesn't really make sense:

* Mountains are made of rock: They're not alive and don't have any biological processes like breathing.

* They have a different kind of "life": Mountains are constantly changing due to erosion, weathering, tectonic activity, and other geological processes. These processes can be thought of as a kind of "life" for a mountain.

If you're interested in how mountains interact with the environment, you could ask:

* How do mountains affect weather patterns?

* What kind of plants and animals live on mountains?

* How do mountains change over time?
