Question

Assertion (A): The physical state of atmosphere at a given place and time is weather.
Reason (R): Long-term aspect of weather is known as climate.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

To distinguish between the two: Weather tells you what clothes to wear today; Climate tells you what types of clothes to buy for your wardrobe. Both are true, but one does not cause the other.

Answer 1

The Correct Option is B

Step 1: Evaluating the Assertion (A):
Weather is defined as the day-to-day, short-term physical state of the atmosphere at a specific time and location. It is measured in terms of variables like temperature, humidity, wind velocity, atmospheric pressure, cloud cover, and precipitation. Therefore, the assertion is True.

Step 2: Evaluating the Reason (R):
Climate is defined as the average weather pattern of a specific geographic region recorded over a long period (typically 30 years or more). Therefore, the reason is also True.

Step 3: Determining the Logical Link:
Does the fact that "the long-term aspect of weather is climate" (R) explain why "the physical state of the atmosphere at a given place and time is weather" (A)?
No. Weather is defined as a short-term phenomenon because of its rapid, localized, and variable physical nature. The definition of climate (R) is a statistical extension of weather data over time, but it does not serve as the causal explanation or scientific origin for the short-term definition of weather (A). Since both statements are independently true facts but lack a direct cause-and-effect relationship, option (B) is the correct choice.
