Answer
Climate change can lead to increased frequency of extreme weather events, which can displace populations, cause damage to infrastructure, and threaten food security. For example, rising sea levels can inundate coastal communities, leading to loss of homes and agricultural land.

Answer
Air from the Equator rises and moves towards the poles, then cools down and sinks at approximately 30° north and south of the Equator. The sinking air creates an area of high pressure with very little rainfall. Some of the air moves back to the Equator as surface winds which contribute to the circulation patterns.

Answer
To find the median, we first list the number of deaths in order: 3,000, 5,000, 11,000, 14,000, 14,500, 16,000, 23,000. The median number of deaths is 14,500.
Step 10

Answer
The number of deaths caused by tropical storms varies due to factors such as population density and preparedness of the affected area. Highly populated areas with inadequate disaster response systems are likely to experience higher fatalities.
