Question

Q.1 ) Answer in short :

1. What happens to the air as we go on higher altitudes?
​

Answer 1

As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other. The human body reacts to high altitudes.

Answer 2

The air becomes less dense.

• The proper stretch upwards from sea level is known as altitude, and it is linked to air pressure.
• Air pressure decreases as altitude increases. To put it another way, if the height displayed is steep, the air pressure is low.
• Gravity is the possible explanation for this. The gravitational attraction of the Earth rends air as close to the surface as feasible.
• Another consideration is density. As altitude rises, the quantity of gas molecules in the atmosphere decreases, causing the air little dense than at sea size.
