Lapse Rate
How quickly air cools with regard to altitude

Average: from sea level to 11km → -10° for every 150m, ELR

Plates crumpling

* Monocline → step-like fold
* Anticline → arch-like fold
* Sincline → u-shaped fold
* Overturned → folded on itself

Human Challenges
Altitude:

* Altitude sickness → less oxygen per breath, hypoxia,
* 8000m+ death zone → not enough oxygen for the body to build new tissue
* AMS → acute mountain sickness

Cold:
