Consider the following statements about Cyclones1. Cyclone is a chain...
Explanation:
Cyclones:
- Cyclones are large-scale weather systems that form over warm ocean waters and are characterized by strong winds and heavy rainfall.
- They are known by different names in different parts of the world. In the Philippines and Japan, they are called 'hurricanes', while in the American continent, they are called 'typhoons'. In other regions, they may also be referred to as 'tropical storms' or 'severe tropical cyclones'.
- Cyclones are formed when warm, moist air rises from the ocean surface and meets cooler air higher up in the atmosphere. This causes the air to condense and form clouds, releasing large amounts of energy in the process.
- As the warm air continues to rise and cool, it creates a low-pressure system at the surface. The rotation of the Earth causes the air to rotate around this low-pressure area, resulting in the formation of a cyclone.
- The winds in a cyclone can reach very high speeds, often exceeding 74 miles per hour. These strong winds can cause extensive damage to infrastructure, uproot trees, and create storm surges, leading to flooding in coastal areas.
- The center of a cyclone is characterized by a calm area known as the 'eye'. The eye is surrounded by a circular wall of clouds called the 'eyewall', where the most intense winds and rainfall occur.
Statements:
1. True: A cyclone is a chain of events that ends with the formation of a very low-pressure system with very high-speed winds revolving around it. The process involves the rising of warm, moist air, the formation of clouds, and the release of energy, leading to the creation of a low-pressure system and the rotation of winds around it.
2. False: The statement is partially correct. In the Philippines and Japan, cyclones are called 'typhoons', not 'hurricanes'. The term 'hurricane' is primarily used in the Atlantic and Northeast Pacific regions.
3. True: The center of a cyclone is indeed a calm area known as the 'eye' of the storm. This is where the pressure is the lowest and the winds are relatively calm. The eye is surrounded by the eyewall, which is where the most intense winds and rainfall occur.
Correct Answer: The correct answer is option (a) 1 and 3 only.
