Answer:
Strength and temperature/conditions
Step-by-step explanation:
Strength: To climb the mountain, it would take a bunch of core and upper body strength to climb up.
Temperature: It is extremely cold and it gets colder as you get higher up on the mountain, so you would probably need to understand how long your going to climb the Mountain and how long you will be able to withstand the cold.
Hope this helped you out! :)
