Question
In Global Warming, the temperature of which part of the Atmosphere increases?
a. Troposphere
b. Mesosphere
c. Stratosphere
d. Ionosphere
Solution
Sure, let's analyze the question step by step:
-
Understanding Global Warming: Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide, methane, and nitrous oxide.
-
Atmospheric Layers: The Earth's atmosphere is divided into several layers:
- Troposphere: The lowest layer, where weather occurs and where most of the atmospheric mass is found.
- Stratosphere: Above the troposphere, contains the ozone layer which absorbs and scatters ultraviolet solar radiation.
- Mesosphere: Above the stratosphere, where temperatures decrease with altitude.
- Ionosphere: A part of the thermosphere, characterized by ionized particles and significant for radio communication.
-
Effect of Global Warming on Atmospheric Layers:
- Troposphere: Global warming primarily affects the troposphere, causing an increase in temperature due to the enhanced greenhouse effect.
- Stratosphere: The stratosphere can experience cooling as a result of global warming because the increased greenhouse gases trap more heat in the troposphere, reducing the amount of heat that reaches the stratosphere.
- Mesosphere: Similar to the stratosphere, the mesosphere can also cool as a result of global warming.
- Ionosphere: The ionosphere is less directly affected by global warming compared to the lower layers.
-
Conclusion: Based on the above analysis, the temperature of the Troposphere increases due to global warming.
So, the correct answer is: a. Troposphere
