Which of the following graphs illustrates the layered structure of the atmosphere? (A)  (B)  (C)  (D)  - HSC - SSCE Chemistry - Question 8 - 2004 - Paper 1

To answer the question, we must understand the general structure of the Earth's atmosphere, which consists of layers: the Troposphere, Stratosphere, Mesosphere, and Thermosphere. The correct graph should display the temperature variations in relation to altitude for these layers. In general:

• The Troposphere is characterized by a decrease in temperature with altitude.
• The Stratosphere shows a temperature increase with height due to the ozone layer.
• The Mesosphere has a decreasing temperature trend, and
• The Thermosphere has a significant increase in temperature with altitude.

After evaluating the options, graph (D) accurately represents this layered structure with the correct temperature profile for each atmospheric layer.
