Question 1

Which of these is an example of weather?
A) The yearly mean temperature in Alberta over a ten-year period
B) A graph showing atmospheric pressure trends worldwide over a five-year period
C) The average level of precipitation across Ontario from July 2013-17
D) A rainstorm in Waterloo on a Thursday in April
E) None of these

Accepted Answer

A rainstorm in Waterloo on a Thursday in April is a specific event that falls under the category of weather. The other answer choices are discussing climate or trends over a period of time rather than a specific weather event.

Question 2

refers to the short-term environmental conditions on a specific day that can change quickly (rainy or dry, cold or hot, clear or cloudy), while can be thought of as an average of the conditions over a longer period (months or years). Which of these combinations fit into the statement above?
A) Weather, climate, weather
B) Climate, meteorology, climate
C) Weather, meteorology, weather
D) Climate, weather, climate
E) Meteorology, climate, meteorology

Accepted Answer

The statement is clearly distinguishing between short-term environmental conditions (weather) and long-term average conditions (climate). Therefore, the answer must include both terms, and the only option that does so in the correct order is A. Choice B substitutes meteorology for weather, which is incorrect, as meteorology is the study of weather and not a term for short-term environmental conditions. Choice C uses meteorology for climate, which is also incorrect, as meteorology is the study of weather and not a term for long-term average conditions. Choice D swaps the order of weather and climate in the second half of the statement, which is not accurate. Choice E uses meteorology twice, which is not correct as explained above.

Question 3

How is visibility measured?
A) Distance at which a black object can be seen against a white background
B) Distance at which a light object can be seen against a dark background
C) By measuring fog intensity
D) By measuring how dark the surrounding environment is
E) A & B

Accepted Answer

Visibility is typically measured by the distance at which a black object can be seen against a white background and the distance at which a light object can be seen against a dark background. So, the correct answer is E) A & B.

Question 4

Which of the following statements is correct
A) METAR describes the weather predicted in the area around an airport
B) ATIS refers to information on moderate weather phenomena
C) VOLMET describes regional weather information for aircraft in flight
D) GAMET is a report created by the pilot that describes significant weather that has been observed during a flight.
E) TAF describes the climate in the area around an airport

Accepted Answer

VOLMET provides weather information for aircraft in flight across multiple regions. METAR provides current weather observations at an airport. ATIS provides information on airport conditions and significant weather phenomena affecting the airport. GAMET is a report created by meteorological authorities and not by the pilot. TAF provides a forecast of expected weather conditions at an airport.

Question 5

This weather hazard presents a high risk of engine malfunction and flame outs, and should be avoided at all costs.
A) Tornado
B) Lightning
C) Icing
D) Rainstorm
E) Volcanic ash

Accepted Answer

Volcanic ash is highly abrasive and can cause significant damage to an aircraft's engines, leading to malfunctions or flameouts. Unlike other weather phenomena, volcanic ash can melt inside the engine and then solidify on cooler parts, causing the engine to shut down.

Question 10

Which statement is true of the general relationship between air pressure/temperature and altitude?
A) For every 1000-foot gain in altitude Temperature decreases about 2 degrees Celsius
B) For every 1000-foot gain in altitude Temperature increases about 2 degrees Celsius
C) For every 1000-foot gain in altitude Air Pressure increases by 22hg per inch of mercury
D) For every 1000-foot loss in altitude Air Pressure decreases by 22hg per inch of mercury
E) None of these

Accepted Answer

According to the standard atmosphere model, temperature decreases at a rate of approximately 2 degrees Celsius per 1000 feet of gain in altitude. This is known as the lapse rate.

Question 11

Standard pressure altitude is a useful tool for pilots. By comparing the conditions at an airport to the standard, they can quickly estimate how their aircraft will perform on a given day. Which of these statement is true about standard and actual pressure altitudes?
A) If the pressure that day is above the standard, aircraft performance will be lower.
B) Standard pressure altitude doesn't affect aircraft performance.
C) If the pressure that day is below the standard, aircraft performance will be higher.
D) If the pressure that day is above the standard, aircraft performance will be higher.
E) None of these

Accepted Answer

If the pressure that day is above the standard, the air is denser, which generally improves aircraft performance due to better lift and engine efficiency.

Question 12

When ascending during a flight, the presence of clouds indicates that the outside temperature has reached
A) 0 degrees Celsius
B) The point of no return
C) The dew point
D) The condensation barrier
E) All of these

Accepted Answer

Clouds form when the temperature reaches the dew point, which is the temperature at which water vapor in the air condenses into visible water droplets or ice crystals. As an airplane ascends, the outside temperature drops, potentially causing the dew point to be reached and leading to cloud formation. Therefore, the presence of clouds indicates that the outside temperature has reached the dew point.

Question 13

A large chunk of air that develops certain characteristics because of its location on the planet is called a(n):
A) Air mass
B) Cyclone
C) Wind event
D) Dew point
E) None of these

Accepted Answer

An air mass is a large chunk of air that develops certain characteristics because of its location on the planet. These characteristics include temperature, humidity, and pressure. Air masses are classified based on their temperature and moisture content, and they play a significant role in determining the weather patterns in different regions.

Question 14

What type of lifting occurs when air is pushed upwards because of rising terrain?
A) Convective
B) Orographic
C) Frontal
D) Convergent
E) Irregular

Accepted Answer

Orographic lifting occurs when air is pushed upwards as it encounters rising terrain, such as a mountain range. This can lead to the formation of clouds and precipitation.

Question 15

Which era is used as a benchmark to understand the impact of human activities on the world's atmosphere?
A) 1950-1980
B) 1920-1970
C) 1880-1920
D) 1850-1900
E) 1900-1950

Accepted Answer

The era of 1850-1900 is known as the pre-industrial era, meaning that it was before significant human industrial activities began to impact the atmosphere. Therefore, it serves as a benchmark for understanding the natural state of the atmosphere and how human activities have altered it since then.

Question 16

Greenhouse gases are
A) All bad
B) Necessary to support life on earth
C) Never a problem for humanity
D) All three are correct
E) None of these

Accepted Answer

Greenhouse gases, such as carbon dioxide and water vapor, are necessary to support life on Earth as they help to keep the planet warm enough to sustain living organisms. However, an excess of greenhouse gases caused by human activity, such as burning fossil fuels, can contribute to climate change and have negative impacts on the planet. Therefore, while greenhouse gases are not all bad, it is important to be aware of and address their potential negative effects.

Question 17

Which of these is NOT contributing to climate change?
A) Water vapor
B) Carbon dioxide
C) Methane
D) Nitrous oxide
E) They all contribute to climate change

Accepted Answer

All the listed gases, including water vapor, carbon dioxide, methane, and nitrous oxide, contribute to climate change. They are known as greenhouse gases, which trap heat in the atmosphere and lead to global warming.

Question 18

Human-driven climate change is difficult to fix because
A) Aircraft are becoming less fuel efficient
B) Controlling carbon will likely lead to massive inflation as the economy grows rapidly
C) Not everyone is on board with the science or they don't think making changes is worth it
D) We don't have any good options for energy production other than fossil fuels
E) None of these

Accepted Answer

While there are many factors that contribute to the difficulty of fixing human-driven climate change, one of the biggest obstacles is the lack of universal agreement on the science and the urgency of making changes. Additionally, some people may see the cost of making changes as too high or may not be willing to change their lifestyles. Even with widespread agreement on the need to take action, there will still be challenges in implementing solutions that are effective and sustainable.

Question 19

Which of these was an international convention related to climate change?
A) Kyoto Protocol
B) Rio Convention
C) Paris Agreement
D) A, B & C
E) None of these

Accepted Answer

A) The Kyoto Protocol was an international treaty signed in 1997 to reduce greenhouse gas emissions. 
B) The Rio Convention, also known as the United Nations Framework Convention on Climate Change (UNFCCC), was signed in 1992 to address global climate change. 
C) The Paris Agreement was signed in 2015 and is an international treaty to mitigate climate change by limiting global warming to below 2 degrees Celsius above pre-industrial levels. Thus, all three options (A, B, & C) are international conventions related to climate change.
