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 we 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

Hint: 1)Mountaineering is the process of climbing mountains.
Regular climbing, as well as muscle strength, can increase stamina and endurance. 2)Furthermore, all the reaching and extending for holds increases stability and flexibility.
3)It is also good aerobic exercise to get out and about in the open air, walking to reach the crag that you want to climb on.
4)The best time for mountaineering is during the season of spring, early autumn and summer to avoid snowfalls and cold temperatures.

Complete answer:
The total value we require to climb is the weight of the body times the height we need to climb, in the horizontal plane the energy required for walking. If there are two different paths to climb the mountains, one steep and the other is less steep, then we will feel fatigue in the steeper path.

As the body is carried down while we come down the hill, we require only a little energy due to the gravitational pull.

While descending our muscles do less work as a result, we do not feel tired.
The climate of mountains is generally cold. Our body needs extra energy to keep itself warm.

Hence, the correct answer is option (C)

Note: 1)Walking on mountains is difficult compared to walking on plains as the surface on mountains is rough whereas the surface of the plains is flat.
2)Our muscles take extra strain when we are climbing the mountains, hence more energy is spent and also because of high altitudes, the air is thin and our body doesn’t get enough oxygen in mountains.
