Gases in the Atmosphere Quiz

During a science class, Gokul asked the teacher, 'What are the two most abundant gases in the Earth's atmosphere?'

• argon and methane

• hydrogen and neon

• nitrogen and oxygen

• carbon dioxide and helium

What is the approximate percentage of oxygen in the Earth's atmosphere?

• 21%

• 30%

• 10%

• 50%

Which gases are considered as greenhouse gases?

• Oxygen, nitrogen, argon

• Water vapor, sulfur dioxide, carbon monoxide

• Carbon dioxide, methane, nitrous oxide, and fluorinated gases

• Hydrogen, helium, neon

During a science class, Gokul asked his teacher, 'How do greenhouse gases contribute to global warming?'

• By reflecting heat away from the Earth's atmosphere

• By trapping heat in the Earth's atmosphere

• By reducing the amount of sunlight reaching the Earth's surface

• By creating a cooling effect in the Earth's atmosphere

What are the main sources of atmospheric pollution?

• Release of helium balloons

• Emissions from electric vehicles

• Burning of plastic waste

• Industrial emissions, vehicle exhaust, agricultural activities, and burning of fossil fuels

How does atmospheric pollution affect the health of individuals?

• Atmospheric pollution has no impact on human health

• Atmospheric pollution only affects plants, not humans

• Atmospheric pollution improves human health

• Atmospheric pollution can lead to respiratory problems, cardiovascular diseases, and other health issues.

What causes smog and how is it formed?

• Smog is formed by the reaction of emissions from vehicles, industrial facilities, and other sources with sunlight.

• Smog is formed by the reaction of emissions from plants and trees with sunlight.

• Smog is formed by the reaction of emissions from wind turbines with sunlight.

• Smog is formed by the reaction of emissions from cooking activities with sunlight.

During a science class, Jayram asked his teacher about the effects of smog on the environment. How would you respond?

• Smog can lead to respiratory problems, reduced visibility, and damage to plants and ecosystems.

• Smog has no impact on the environment

• Smog improves air quality

• Smog only affects human health

During a science class, Jayram asked his teacher, 'What role does water vapor play in the Earth's atmosphere?'. How did the teacher respond?

• It has no impact on the Earth's atmosphere

• It causes extreme weather events

• It depletes the ozone layer

• It helps regulate the Earth's temperature and climate.

During a science experiment, Jayram observed the process of how water vapor contributes to the formation of clouds and precipitation. What did he conclude?

• Water vapor condenses to form clouds and precipitation.

• Water vapor freezes to form clouds and precipitation.

• Water vapor evaporates to form clouds and precipitation.

• Water vapor sublimates to form clouds and precipitation.
