Mesosphere and Thermosphere

What is the height range of the mesosphere?

• 0 to 15 kilometers

• 50 to 85 kilometers

• 85 to 100 kilometers

• 100 to 150 kilometers

Which instruments are mentioned as useful for studying the mesosphere?

• Weather balloons

• Satellites

• Airplanes

• Special rockets

What do most people think of the thermosphere and exosphere?

• They are the densest layers of the atmosphere.

• They are not part of space.

• They are considered part of space, not part of the Earth's atmosphere.

• They have the most weather activity.

Why can't weather balloons or planes study the mesosphere effectively?

• They cannot withstand the cold temperatures.

• They cannot fly high enough.

• They are too heavy to reach the mesosphere.

• They are designed only for the troposphere.

What is one method scientists use to gather data about the mesosphere?

• Sending satellites into orbit

• Launching special rockets that return after data collection

• Using weather balloons that float to the mesosphere

• Observing the mesosphere from the ground with telescopes

Which layer of the atmosphere lies directly above the mesosphere?

• Troposphere

• Exosphere

• Stratosphere

• Thermosphere

Why do meteorologists NOT know much about the mesosphere?

• The mesosphere was only discovered about ten years ago.

• Not many instruments can reach that part of the atmosphere.

• The mesosphere's weather is very violent and therefore dangerous to study.

• The mesosphere tends to change position depending on the weather.

What is the purpose of paragraph 7?

• To explain why scientists don't know much about the mesosphere

• To mention a few interesting things that scientists know about the mesosphere

• To explain how scientists plan to learn more about the mesosphere in the future

• To explain why the mesosphere is the least important layer of the atmosphere

All of the following are true according to paragraph 8 EXCEPT

• The mesosphere and the thermosphere are above the exosphere.

• The thermosphere and the exosphere are very thin layers of the atmosphere.

• Most people consider the thermosphere and the exosphere to be part of space.

• Air molecules in the thermosphere and the exosphere don't often strike each other
