Question

Which of the following statement(s) is/are correct with regard to air pressure? 
(A) High pressure is related to cloudy sky and wet weather 
(B) Low pressure is associated with clear and sunny skies 
(C) The air always moves from high pressure to low pressure areas 
(D) Low pressure involves air rising from earth's surface 
Choose the correct answer from the options given below:

• A. (A) and (B) only
• B. (A), (B) and (C) only
• C. (A), (B), (C) and (D)
• D. (C) and (D) only

Hint:

Air moves from high pressure to low pressure areas, and low pressure involves rising air which leads to cloud formation and precipitation.

Answer 1

The Correct Option is D

Step 1: Analyzing the Statements.
- (A) High pressure is associated with fair weather, clear skies, and dry conditions, not with cloudy and wet weather. This statement is incorrect.
- (B) Low pressure is typically associated with cloudy and rainy weather, not clear and sunny skies. Hence, this statement is also incorrect.
- (C) Air always moves from regions of high pressure to regions of low pressure, which is true and follows the basic principles of meteorology.
- (D) Low pressure involves rising air from the Earth's surface, which is a correct statement.

Step 2: Conclusion.
Therefore, the correct statements are (C) and (D), making option (4) the correct answer.

Final Answer: \[ \boxed{4. \, (C) \, \text{and} \, (D) \, \text{only}} \]
