Question 27

Hurricanes are typically over 160 kilometers in diameter and can have sustained wind speeds that exceed 200 kilometers per hour.

Hurricanes are large storm systems that can span extensive areas, typically measuring over 160 kilometers (or 100 miles) in diameter. They are also capable of producing sustained wind speeds that can surpass 200 kilometers (or 124 miles) per hour.

A) They are typically over 160 kilometers, or 100 miles, in diameter.

This statement is true. Hurricanes are massive systems that can cover vast distances, often exceeding 160 kilometers in diameter, which is a defining characteristic of these storms.

B) They form over cold water in Earth's Polar Regions and move toward the equator.

This statement is incorrect. Hurricanes actually form over warm ocean waters, primarily in tropical regions, where the heat from the water fuels their development. They do not typically originate in cold waters or polar regions.

C) They develop quickly and usually last for less than 30 minutes.

This statement is false. While hurricanes can develop relatively quickly, they usually last much longer than 30 minutes. Many hurricanes can persist for several days or even weeks, depending on environmental conditions.

D) They can have sustained wind speeds that are over 200 kilometers, or 124 miles, per hour.

This statement is true. Hurricanes can indeed have sustained wind speeds exceeding 200 kilometers per hour, particularly in the strongest categories, making them extremely dangerous weather phenomena.

Conclusion

The accurate statements about hurricanes are that they are typically over 160 kilometers in diameter and can achieve sustained wind speeds of over 200 kilometers per hour. The other options are incorrect as they misrepresent the formation conditions and duration of hurricanes, highlighting the importance of understanding the true nature of these powerful storms.
