Effect of Pollutants on Atmosphere

The pollutants in troposphere cause:

• Improved air quality and environmental protection
• Reduced greenhouse gas emissions and climate change
• Healthier ecosystems and cleaner water
• Air pollution and environmental damage

Smog is a mixture of:

• Smog is a mixture of sand and fog.
• Smog is a mixture of snow and fog.
• Smog is a mixture of sun and fog.
• Smog is a mixture of smoke and fog.

A mixture of SO₂, Aerosol & VOC's produces:

• global warming

• ozone

• Smog

• acid rain

A brown-yellow layer in industrial areas produces due to:

• Excessive rainfall and waterlogging
• Overuse of fertilizers and pesticides
• Air pollution and the formation of sulfur dioxide and nitrogen oxides.
• Natural soil erosion and weathering

Global Warming is defined as:

• The long-term heating of Earth’s climate system which increases the concentration of greenhouse gases in the atmosphere.

• Global Warming is a hoax created by scientists to get more funding
• Global Warming is caused by the Earth moving closer to the sun
• Global Warming is a natural cycle that has nothing to do with human activities

Which pair represents green house gases:

• COx, NOx, SOx

• CO₂, H₂O, VOC's

• CO₂, CH₄, H₂O, N₂O

• O₃, VOCs

The average temperature of earth is approximately:

• 0^oC

• 10^oC

• 15^oC

• 25^oC

Due to global warming:

• There are increased temperatures, melting ice caps, rising sea levels, and extreme weather events.

• There are decreased temperatures and freezing ice caps.

• There are no changes in sea levels or extreme weather events.

• There are more trees and greener landscapes.

A natural process that traps heat in the Earth's atmosphere, making it warmer:

• Global Warming

• Acid Rain

• Greenhouse effect
• Irrigation

The main cause of global warming is:

• The decrease in greenhouse gases

• The cooling effect of aerosols in the atmosphere

• The increase in greenhouse gases, such as carbon dioxide and methane, due to human activities like burning fossil fuels and deforestation.

• The natural climate cycles
