Breathing Life: Earth's Atmosphere Picture our planet wrapped in an invisible, life-giving blanket that stretches from the ground beneath your feet to the edge of space. This is the atmosphere – a dynamic, ever-changing system that's been silently supporting life for billions of years...well, thank you dear! It is retained by Earth's gravity, so that it can stay with us and most of its mass (~98%) is below  ~ 25km.

Let's revise some basic concepts Hello and welcome to the very first post of the Geoscience section ! We will talk more about the scientific aspects of our planet: to enjoy a good hike, you should know something about what you're stepping on or what's around you. So, I'd like to start off with a little introduction to the dynamics of our atmosphere; there's so much going on yet we take too many things for granted, so I want to make a couple of things clear before diving into the more interesting facts, so you have a solid base for future posts, so nice of me. L et's start!
