Question

Global warming leads to

• A. falling of sea level
• B. lowering of the average temperature of earth
• C. static weather pattern
• D. melting of ice caps at slower rate
• E. expansion of desert

Hint:

Global warming generally leads to higher temperatures, melting glaciers, rising sea levels, and expansion of dry regions.

Answer 1

Answer: (E)

Step 1: Understand the concept of global warming.
Global warming refers to the gradual increase in the average temperature of the Earth due to the greenhouse effect caused by gases such as carbon dioxide, methane, etc.

Step 2: Identify its major environmental impacts.
Due to increased temperature, several changes occur such as melting of ice caps, rising sea levels, extreme weather events, and changes in precipitation patterns.

Step 3: Analyze option (1).
Falling of sea level is incorrect because melting glaciers and thermal expansion of oceans actually cause sea levels to rise.

Step 4: Analyze option (2) and (3).
Global warming increases the Earth's temperature, not decreases it, so option (2) is incorrect. Also, weather patterns become more irregular and extreme, not static, so option (3) is incorrect.

Step 5: Analyze option (4).
Ice caps melt at a faster rate due to global warming, not slower, so this option is incorrect.

Step 6: Analyze option (5).
Due to rising temperatures and reduced rainfall in some regions, deserts expand and arid regions grow larger. This is a direct consequence of global warming.

Step 7: State the final answer.
Hence, the correct effect of global warming is:
\[ \boxed{\text{expansion of desert}} \] which matches option \((5)\).
