Q: 50 (NDA-I/2010)

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.

{'areas': [0, 0, 1, 0], 'low pressure': [1, 1, 7, 8], 'area': [0, 0, 0, 1], 'cyclone': [1, 1, 2, 3], 'high pressure': [1, 0, 8, 4]}

In a cyclone, the correct statement is option 2: the areas of low pressure surround the area of high pressure. This is because in a cyclone, there is a central area of low pressure where air rises rapidly, causing air from the surrounding areas of high pressure to rush in and replace it. This creates a rotating motion and a cyclonic weather system.

Option 1 is incorrect because it states that the area of low pressure is at the center surrounded by areas of high pressure. In a cyclone, the opposite is true, with the low-pressure system surrounding the high-pressure system.

Option 3 is incorrect because it refers to an anti-cyclone, which is the opposite of a cyclone. In an anti-cyclone, the area of high pressure is indeed surrounded by areas of low pressure. Anti-cyclones are characterized by descending air, which causes the air to spread out and create higher pressure at the center.

Option 4 is incorrect because it states that in an anti-cyclone, the area of low pressure is surrounded by areas of high pressure. This is not true for an anti-cyclone, as explained above.

Therefore, the correct statement is option 2: in a cyclone, the areas of low pressure surround the
