Consider the following pairs: Layers of Atmosphere Characteristics...
Consider the following pairs:
How many of the pairs given above are correctly matched?
| Layers of Atmosphere | Characteristics |
|---|---|
| I. Troposphere | Absorbs ultraviolet radiation |
| II. Stratosphere | Changes in weather and climate |
| III. Mesosphere | Reflects radio waves back to the Earth |
How many of the pairs given above are correctly matched?
Options
- ANone
- BOne
- CTwo
- DAll the three
Correct answer
A. None
Step-by-step solution
The troposphere is the lowest layer of the atmosphere where all changes in weather and climate take place. The given characteristic for the troposphere is incorrect.
The stratosphere contains the ozone layer, which absorbs harmful ultraviolet radiation from the sun. The given characteristic for the stratosphere is incorrect.
The ionosphere (a part of the thermosphere) contains electrically charged particles called ions, which reflect radio waves back to the Earth. The mesosphere is the layer where meteors burn up upon entering the atmosphere. The given characteristic for the mesosphere is incorrect.
Since all three pairs are incorrectly matched, none of the pairs are correct.
Answer: None
