Name the major cause of depletion of ozone layer:
Chlorofluorocarbons (CFCs) are the primary chemicals responsible for the depletion of the ozone layer.
Which gas is emitted by incomplete combustion of fuel:
Carbon monoxide is emitted as a result of incomplete combustion of fuels.
The layer which protects the earth is called:
The ozone layer is crucial for protecting life on Earth by absorbing harmful ultraviolet radiation from the sun.
Which gas from the following is mainly responsible for Green House effect in the environment?
Carbon dioxide is the primary greenhouse gas contributing to global warming and the greenhouse effect.
The poisonous gas which is the main byproduct of motor vehicle with irritating smell is:
Sulphur Dioxide is a poisonous gas emitted by motor vehicles, known for its irritating smell and harmful effects on health.
The ozone layer is present in the atmosphere approximately:
The ozone layer is located approximately 12 to 50 kilometers above the Earth's surface.
What are substances that damage the environment called?
Substances that damage the environment are called pollutants.
Which of the following is a consequence of pollution?
Acid rain is a direct consequence of pollution, particularly from sulfur dioxide and nitrogen oxides emissions.
What does the greenhouse effect lead to?
The greenhouse effect leads to global warming by trapping heat in the Earth's atmosphere.
Depletion of which layer is a result of pollution?
Pollution leads to the depletion of the ozone layer, which protects the Earth from harmful UV radiation.
What is pollution?
Pollution refers to harmful changes in the environment, often caused by human activities.
What are pollutants?
Pollutants are harmful substances that contaminate the environment.
Which of the following is a major air pollutant?
Carbon monoxide is a major air pollutant, primarily emitted from vehicle exhausts and industrial processes.
Which gas has a strong irritating smell and causes bronchitis and asthma?
Sulfur dioxide is known for its strong irritating smell and can cause respiratory issues such as bronchitis and asthma.
What health issue is commonly caused by air polluted with Sulfur Dioxide?
Sulfur Dioxide pollution commonly leads to asthmatic attacks due to its irritating effects on the respiratory system.
Carbon Monoxide mainly affects the:
Carbon Monoxide primarily affects the cardiovascular system by reducing the blood's ability to carry oxygen.
Which gas is colorless, odorless, and causes headaches and fatigue?
Carbon monoxide is a colorless, odorless gas that can cause headaches and fatigue due to its interference with oxygen delivery in the body.
A common source of Carbon Monoxide is:
A common source of carbon monoxide is the incomplete combustion of fuels, such as in vehicle engines and heating systems.
A harmful effect of Nitrogen Dioxide is:
Nitrogen Dioxide can cause lung irritation and respiratory problems, particularly in individuals with pre-existing conditions.
Which pollutant is responsible for smog formation?
Nitrogen dioxide is a key pollutant responsible for the formation of smog, particularly in urban areas.
Which pollutant causes ozone layer depletion?
Chlorofluorocarbons (CFCs) are the primary pollutants responsible for the depletion of the ozone layer.
What environmental issue is caused by the emission of carbon dioxide and other gases?
The emission of carbon dioxide and other greenhouse gases leads to global warming by trapping heat in the atmosphere.
Which gases contribute to the formation of acid rain?
Sulfur dioxide and nitrogen oxides are the primary gases that contribute to the formation of acid rain.
What gas is mainly responsible for the greenhouse effect?
Carbon dioxide is the primary gas responsible for the greenhouse effect, trapping heat in the Earth's atmosphere.
What is the greenhouse effect?
The greenhouse effect refers to the trapping of heat by greenhouse gases in the Earth's atmosphere, leading to global warming.
What is the result of increased greenhouse gases?
Increased levels of greenhouse gases result in global warming by enhancing the heat-trapping capability of the Earth's atmosphere.
Where is the ozone layer located in the Earth's atmosphere?
The ozone layer is located approximately 12 to 50 kilometers above the Earth's surface in the stratosphere.
What is the main function of the ozone layer?
The main function of the ozone layer is to protect life on Earth by absorbing harmful ultraviolet radiation from the sun.
Which chemical is the major source of chlorine that breaks down ozone?
Chlorofluorocarbons (CFCs) are the major source of chlorine that contributes to the breakdown of ozone in the ozone layer.
What is a harmful effect of ozone layer depletion on humans?
Ozone layer depletion increases the risk of skin cancer in humans due to higher levels of ultraviolet radiation reaching the Earth's surface.
What is deforestation?
Deforestation refers to the permanent destruction of forests, often for agricultural or urban development purposes.
Which gas emission increases due to deforestation?
Deforestation leads to increased emissions of carbon dioxide, as fewer trees are available to absorb this greenhouse gas.
What environmental issue is caused by the removal of trees?
The removal of trees can lead to environmental issues such as flooding and soil erosion due to the loss of root systems that stabilize the soil.
