Estratosfera

The video explains the mesosphere's height and its thinner presence over the poles. It discusses how temperature in the stratosphere increases with altitude and highlights the efficiency benefits for airlines traveling through the lower stratosphere due to the cold air layer.

What is the height range of the mesosphere?

• 5 to 20 km

• 10 to 50 km

• 50 to 100 km

• 100 to 150 km

What is one characteristic of the mesosphere?

• It contains the ozone layer

• It is slightly thinner over the poles

• It is the hottest layer

• It is the closest layer to Earth

How does the temperature change in the stratosphere as altitude increases?

• It fluctuates

• It increases

• It remains constant

• It decreases

Why do airlines prefer to travel through the lower part of the stratosphere?

• For better communication signals

• To reduce travel time

• For better fuel efficiency

• To avoid turbulence

What role does the thin layer of cold air in the stratosphere play for airplanes?

• It increases drag

• It reduces engine efficiency

• It contributes to engine efficiency

• It causes turbulence
