Question : Statement 1: Global warming is primarily caused by an increase in greenhouse gas emissions, such as carbon dioxide and methane.
Statement 2: These gases trap heat in the Earth's atmosphere, leading to a rise in average global temperatures.
Option 1: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Option 2: Both statement 1 and statement 2 are true, but statement 2 is not the correct explanation of statement 1 .
Option 3: Statement 1 is true, but statement 2 is false.
Option 4: Statement 1 is false, but statement 2 is true.
Correct Answer: Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Solution : The correct answer is (A) Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1.
Statement 1 is accurate in stating that global warming is primarily caused by an increase in greenhouse gas emissions. Greenhouse gases, including carbon dioxide and methane, have the ability to trap heat in the Earth's atmosphere, leading to the greenhouse effect. This is well-established scientific knowledge.
Statement 2 provides the correct explanation for statement 1. It explains that these greenhouse gases, once emitted into the atmosphere, act as a "blanket" that traps heat and prevents it from escaping into space. This trapped heat causes a rise in average global temperatures, contributing to global warming.
Therefore, both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
