Topic 6 Review DP ESS

Identify one primary pollutant from the following list:

• Ozone

• Nitrogen oxides (NOx)

• Carbon dioxide (CO2)

• Methane (CH4)

Why is nitrogen oxide referred to as a primary pollutant?

• It forms after reacting with other pollutants in the atmosphere.

• It is directly emitted by human activities without chemical transformation.

• It is naturally produced by vegetation.

• It is beneficial to plants in small amounts.

Which of the following is a reason for increased nitrogen oxides and hydrocarbons in the morning?

• Low levels of sunlight

• Increased vehicle emissions due to morning traffic

• High industrial activity during the night

• Reduced fossil fuel combustion

Which factors contribute to the daily variation of ozone concentration in the troposphere?

• I and II only

• I, II, and III only

• II, III, and IV only

Which of the following local conditions can worsen photochemical smog?

• Low wind speed and warm temperatures

• Frequent rainfall and high wind speed

• Sparse population and low vehicle use

• High-altitude mountainous areas with low sunlight

How do catalytic converters help in reducing photochemical smog?

• By trapping ozone and particulate matter

• By converting nitrogen oxides and hydrocarbons into less harmful substances

• By eliminating all secondary pollutants

• By preventing fossil fuel combustion in vehicles

Which of the following factors is necessary for ozone formation in the troposphere?

• High humidity and low temperatures

• Particulate matter and carbon monoxide

• Sunlight and nitrogen oxides

• Sulfur dioxide and methane

Why is high ozone concentration in the troposphere problematic, while in the stratosphere it is beneficial?

• Tropospheric ozone protects against UV radiation, while stratospheric ozone causes pollution.

• Stratospheric ozone protects against UV radiation, while tropospheric ozone causes respiratory and health issues.

• Both tropospheric and stratospheric ozone are harmful to human health.

• Tropospheric ozone provides oxygen for plants, while stratospheric ozone harms crops.

What contributed to the significant depletion of the ozone layer during the 1980s?

• Natural ozone destruction due to solar flares

• Overuse of chlorofluorocarbons (CFCs) in refrigerants and aerosol sprays

• Reduced industrial activity during the decade

• Ban on ozone-depleting substances during the 1980s

How can the success of the Montreal Protocol in addressing ozone depletion be evaluated?

• Ozone levels continued to worsen, indicating the protocol's ineffectiveness.

• Stabilization and eventual recovery of the ozone layer suggest the protocol's effectiveness.

• Immediate restoration of the ozone layer was observed after the protocol's implementation.

• Ozone-depleting substances (ODS) increased due to enforcement delays.
