True or False: Over the last 30 years, tornadoes are the only weather phenomenon that on average kills more people that flooding in the US each year. Select one: a. True. b. False. Which of the following is an incorrect statement about the "urban heat island". Select one: a. The urban heat island has its greatest effect over night. b. The building materials of the city (concrete, glass, brick, asphalt) absorb the sun's energy keeping the interior of the city hot. c. Some major US cities are using large solar shields to lessen the impact of the urban heat island by blocking the intense afternoon sun in summer. These solar shields can cover up to one square mile when opened. d. The lack of vegetation in the center of large cities can enhance the urban heat island making it hotter. The US uses the USDA Drought Monitor to categorize and map where drought conditions are present in the US. Which of the following statement is not correct about the Drought Monitor? Select one. a. The Drought Monitor is cumulative. It looks at the long term factors that contribute to drought. b. Once a region is classified as D5 Drought stage, the region is climatologically reclassified as a desert or semi-arid climate zone. c. It is based upon the Palmer Drought Severity Index (PDSI). d. The drought monitor is based upon a supply (rainfall, groundwater and streamflow) and use (irrigation, runoff) model for water in a given area.Explanation / Answer
4. Over the last 30 years tornadoes are the only weather phenomenon that on average kills more people than flooding in the U.S each year
Answer: FALSE
Explanation: Due to better predictions for hurricanes the deaths are almost reduced in recent decades. But flooding deaths are increasing regularly.
5. Which of the following is an incorrect statement about the urban heat island
Answer: A. The urban heat island has its greatest effect overnight.
Explanation: Urban heat island during daytime have greater effect compared to overnight because there are no clouds and majority of urban surfaces are warmed by the absorption of solar radiation during daytime.
6. The U.S uses the USDA drought monitor to categorize and map where drought conditions are present in the United States. Which of the following statement is not correct about the drought monitor.
Answer: B. Once a region is classified as D5 drought stage, the region is climatologically reclassified as a desert or semi-arid climate zone.
Explanation: If we observe united states drought monitor it provides database to track the severity of droughts in the united states and the drought severity classification scale ranges from D0(least intense) to D4(most intense). So there is no D5 in the severity scale which makes the statement incorrect.
