FAQs on Thunderstorms - Winds, Storms and Cyclones - CBSE Class 7 Science
| 1. What causes thunderstorms? |  |
Ans. Thunderstorms are caused by the rapid upward movement of warm, moist air. As this warm air rises, it cools and condenses, forming cumulonimbus clouds. These clouds create unstable atmospheric conditions, leading to the formation of thunderstorms.
| 2. How are thunderstorms and cyclones different? | |
Ans. Thunderstorms and cyclones are both types of atmospheric disturbances, but they differ in their size and intensity. Thunderstorms are local and short-lived weather events characterized by lightning, thunder, heavy rain, and strong winds. On the other hand, cyclones are large-scale weather systems that rotate around a low-pressure center, causing widespread destruction over a much larger area.
| 3. What are the dangers associated with thunderstorms? | |
Ans. Thunderstorms can pose various dangers, including lightning strikes, strong winds, heavy rainfall, and flash floods. Lightning can be fatal, and strong winds can cause damage to trees, buildings, and infrastructure. Heavy rainfall can lead to flooding, which can be dangerous for both humans and animals.
| 4. How are thunderstorms formed? | |
Ans. Thunderstorms are formed when warm, moist air rises rapidly and cools in the atmosphere. This cooling causes condensation and the formation of cumulonimbus clouds. These clouds contain strong updrafts and downdrafts, resulting in the development of lightning, thunder, rain, and strong winds.
| 5. Can thunderstorms cause tornadoes? | |
Ans. Yes, thunderstorms can sometimes produce tornadoes. Tornadoes are violent rotating columns of air that extend from a thunderstorm to the ground. They are typically associated with severe thunderstorms, characterized by strong updrafts and wind shear. However, not all thunderstorms produce tornadoes, and tornadoes are relatively rare compared to thunderstorms.
