The video takes viewers on a journey through space to explore Earth's atmospheric layers. Starting with the troposphere, where weather occurs, it moves to the stratosphere, home to the ozone layer. The mesosphere is where meteors burn, followed by the thermosphere, which contains the ionosphere. Finally, the exosphere is the outermost layer. Trivia includes the mass of the troposphere and the ionosphere's role in radio transmission. The video concludes with a return to Earth.

Which layer of the atmosphere is closest to the Earth's surface?

• Mesosphere

• Stratosphere

• Troposphere

• Thermosphere

What happens to the temperature as altitude increases in the Troposphere?

• It fluctuates

• It increases

• It decreases

• It remains constant

Which layer contains the ozone layer?

• Mesosphere

Why do airplanes prefer to fly in the Stratosphere?

• Because it has more oxygen

• Because it is free of weather disturbances

• Because it is warmer

• Because it is closer to space
