Environmental Science Quiz Unit 2 L 2

What is the main reason for the formation of ozone gas in the stratosphere layer?

• Absorption of ultraviolet radiation (UV)

• Combustion of fossil fuels

• Presence of nitrogen gas

• Emission of visible light

What is the standard temperature and pressure known as?

• Standard Temperature and Pressure (STP)

• Normal Atmospheric Conditions

• Average Atmospheric Pressure

• Standard Temperature Pressure

Which type of UV rays penetrates the ozone layer by 100%?

• Far ultraviolet

• All of the above

• Near ultraviolet

• Medium ultraviolet

What is the most dangerous pollutant that is used as a cooling material in air conditioning sets?

• Methyl bromide

• Halons

• Nitrogen oxides

• Chlorofluorocarbon compounds (CFC)

What phenomenon is caused by the increase in the average temperature of the Earth's near-surface air?

• Sea level rise

• Greenhouse effect

• Ozone hole

• Global warming

What is the most important greenhouse gas that has increased in the atmosphere to 0.038% in 2005?

• Methane gas CH4

• Nitrous oxide N2O

• Carbon dioxide gas CO2

• Water vapour H2O

What happens when the rate of greenhouse gases increases in the troposphere?

• The atmosphere permits the visible light and short-waved rays emitted from the sun to pass

• The earth and its components absorb these rays and reemit the radiation back in the form of infrared radiation

• Some of infrared radiation cannot penetrate the atmosphere because it has a long wavelength

• All of the above

What is the trapping of infrared radiation in the troposphere layer due to the increase in the percentage of greenhouse gases known as?

• Sea level rise

• Ozone hole

• Greenhouse effect

• Global warming

What is one of the most dangerous effects of the global warming phenomenon?

• Increase in average temperature

• Melting of polar ice

• Erosion of ozone layer

• Formation of ozone gas

What is the main reason for the disappearance of coastal areas due to the melting of polar ice?

• Rise in sea level

• Severe climatic changes

• Increase in forest fires

• Extinction of polar animals
