Geography is just physics slowed down, with a couple of trees stuck in it. - Terry Pratchett



Notice Board



Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. They also examine how human culture interacts with the natural environment and the way that locations and places can have an impact on people. Geography seeks to understand where things are found, why they are there, and how they develop and change over time. Read more...

What happens to the hydrogen that escapes into space?

The solar radiation (sunlight) slowly accelerates most of it, until it leaves the solar system, more or less.

So in theory some of the air I have breathed is on its way into deep space. That's a fun thought

Yes, but a very very small amount. Most hydrogen gets recombined with oxygen (or nitrogen or carbon) before it escapes, and is too heavy to escape as a water molecule or similar.
