The Atmosphere: Upper Layers of the Atmosphere

The video explains the different layers of Earth's atmosphere, focusing on the stratopause, mesosphere, and thermosphere. The stratopause separates the stratosphere from the mesosphere, which protects Earth by burning up meteors. The mesosphere is extremely cold, while the thermosphere is very hot, reaching temperatures that can melt steel. The thermosphere is further divided into the ionosphere and exosphere.

What is the primary function of the mesosphere in Earth's atmosphere?

• To support the ozone layer

• To separate the stratosphere from the thermosphere

• To protect Earth from meteors by burning them up

• To maintain Earth's temperature

At what temperature does the mesosphere typically exist?

• Around minus 100 degrees Celsius

• Around 100 degrees Celsius

• Around minus 50 degrees Celsius

• Around 0 degrees Celsius

Which atmospheric layer is known for its extremely high temperatures?

• Stratosphere

• Mesosphere

• Thermosphere

• Exosphere

What is the meaning of 'thermo' in thermosphere?

• Heat

• Cold

• Light

• Wind

Into which two layers is the thermosphere divided?

• Ionosphere and Exosphere

• Troposphere and Stratosphere

• Stratosphere and Mesosphere

• Mesosphere and Thermosphere
