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?
None
To determine how many pairs are correctly matched, we need to understand the characteristics of each atmospheric layer:
- Troposphere:
The troposphere is the lowest layer of Earth's atmosphere and is where all weather phenomena occur. It does not absorb significant ultraviolet radiation; instead, this role is mostly carried out by the stratosphere, particularly by the ozone layer within it. Hence, the statement that the troposphere absorbs ultraviolet radiation is incorrect.
- Stratosphere:
The stratosphere is located above the troposphere and contains the ozone layer, which does absorb ultraviolet radiation. The statement given attributes "Changes in weather and climate" to the stratosphere, which is incorrect because these phenomena are primarily associated with the troposphere. Therefore, this pair is also incorrectly matched.
- Mesosphere:
The mesosphere is the third layer of the atmosphere above the stratosphere. It is known for burning up meteors due to its thickness. It does not reflect radio waves; this function is largely associated with the ionosphere (a part of the thermosphere), where free electrons provide the ability to reflect radio waves back to Earth. Thus, this pair is incorrectly matched as well.
Based on the analysis above, none of the pairs are correctly matched. Therefore, the correct answer is None.
