Question

Why do we need extra energy in the mountains?

• A. During mountaineering we have to go up. Thus we spend energy faster.
• B. Due to less air we breathe faster and so need extra energy.
• C. The climate of mountains is generally cold. Our body needs extra energy to keep itself warm.
• D. Food is digested faster in mountains. So we need extra energy.

Answer 1

The correct option is C The climate of mountains is generally cold. Our body needs extra energy to keep itself warm.

When we come down a hill, very little energy is required because the body is carried down the slope due to earth’s gravitational pull.
Our muscles do less work as a result and we do not feel tired while descending. Also, the climate of the mountains is generally cold. Our body needs extra energy to keep itself warm.
