Which of the following statements are correct? 1. In a cyclone, the area of low pressure is at the centre surrounded by the areas of high pressure. 2. In a cyclone, the areas of low pressure surround the area of high pressure. 3. In an anti-cyclone, the area of high pressure is surrounded by the areas of low pressure. 4. In an anti-cyclone, the area of low pressure is surrounded by the areas of high pressure. Select the correct answer using the code given below : Code :
Explanation
A cyclone is a weather system characterized by a central area of low atmospheric pressure surrounded by higher pressure [c1][c2]. This pressure gradient causes air to flow inwards towards the center, resulting in a rotating vortex [c3][t10]. Conversely, an anticyclone is a high-pressure system where the highest pressure is at the center, surrounded by areas of lower pressure [t5][t7]. In an anticyclone, air diverges or flows outward from the central high-pressure zone towards the surrounding lower pressure areas [t4][t7]. Therefore, statement 1 is correct as it describes the low-pressure center of a cyclone, and statement 3 is correct as it describes the high-pressure center of an anticyclone. Statements 2 and 4 are incorrect because they reverse these fundamental pressure patterns [t1][t5].
