20 questions
Question 1: The absorption of long-wave radiation from the Earth's surface by greenhouse gases is attributed to the asymmetry of their molecules, which is caused by electric charge.
A. Yes
B. No
Explanation: Greenhouse gases absorb long-wave radiation from the surface of Earth due to the asymmetry of its molecules. This asymmetry is caused by electric charge, as seen in the case of water vapor.
Question 2: Based on the provided study materials, which of the following statements accurately describe climate trends in Canada?
A. Annual mean temperature in the 20th century increased by 0.5-1.5 degrees.
B. Past and future warming in Canada is approximately double the magnitude of global warming.
C. Warmer winters and earlier snowmelt will result in higher winter stream flows.
D. An increase in summer rainfall is a projected trend, leading to heavier snowpacks.
Explanation: The study materials state that 'annual mean temperature in 20th century increased by 0.5-1.5 degrees', 'both past and future warming in Canada is about double the magnitude of global warming', and 'Warmer winters and earlier snowmelt will produce higher winter stream flows.' The materials also indicate a 'reduction in summer rainfall' and 'less snowfall', which contradicts the idea of an increase in summer rainfall and heavier snowpacks.
Question 3: Flash floods are primarily characterized by slow-moving, widespread water accumulation resulting from prolonged moderate rainfall.
A. Yes
B. No
Explanation: Flash floods are characterized by an intense, high velocity torrent of water triggered by torrential rainfall within a short amount of time within the vicinity or on nearby elevated terrain, not slow-moving widespread accumulation from prolonged moderate rainfall.
Question 4: Which of the following are projected consequences of the amplification of the global water cycle due to climate change, as described in the study materials?
A. Extreme rainfall during thunderstorms and tropical cyclones
B. An increase in horizontal moisture transport
C. A global decrease in sea level
D. Enhanced patterns of evaporation minus precipitation and its temporal variance
Explanation: The study materials state that the amplification of the global water cycle due to climate change will lead to 'extreme rainfall during thunderstorms, hurricanes and tropical cyclones', 'flooding, drought, sea level rise', and an 'increase in horizontal moisture transport'. It also mentions 'associated enhancement of the pattern of evaporation minus precipitation and its temporal variance'. Therefore, extreme rainfall, increased horizontal moisture transport, and enhanced patterns of evaporation minus precipitation are correct consequences. A global decrease in sea level contradicts the stated consequence of 'sea level rise'.
Question 5: GIS is used for monitoring watershed conditions and assessing the impact of interventions.
A. Yes
B. No
Explanation: The study materials state that GIS is used to monitor watershed conditions and assess the impact of interventions.
