While a single one of these is a sight, what I am is way more tight. Peaks, valleys, foot hills abound, I'm like the ground turned upside down. If the answer still eludes, just check out the Appalachians dudes!

Between great heights I stretch below, where rivers carve and wild things grow.

I hug the planet tight, though I have no arms to hold. I shield you from the void of space and guard you from the cold. I carry every sound you hear, I paint the sky in blue, And with every single breath you take, I give life to you.

Take a deep dive into rumor and conspiracy. Take a bite of me? Your stomach growls eerily. As above, so below; If you crash into me, your boat will need a tow.

I wear a coat of permafrost, Where summers are short and the winter's a boss. I am vast, treeless, and bitterly cold, With a layer of ice that is ancient and old. I house grazing herds and the scurrying lemming. What am I?
