One of the followings is not a green house gas....

Methane
Carbon monooxide
Carbon dioxide
Nitrous oxide

Correct Answer

A. Carbon monooxide

Explanation

Carbon monoxide is not considered a greenhouse gas because it does not have the ability to trap heat in the Earth's atmosphere like other greenhouse gases do. Greenhouse gases, such as methane, carbon dioxide, and nitrous oxide, have the ability to absorb and emit infrared radiation, leading to the greenhouse effect and global warming. Carbon monoxide, on the other hand, is primarily produced by the incomplete combustion of fossil fuels and does not possess the same heat-trapping properties as the other gases listed.

Ozone Layer is mainly depleted by....?

Excess carbon monooxide
Excess carbon dioxide
Chlorofluorocarbons (CFC's)
Methane

Correct Answer

A. Chlorofluorocarbons (CFC's)

Explanation

Chlorofluorocarbons (CFC's) are the main cause of ozone layer depletion. When released into the atmosphere, CFC's rise to the stratosphere where they are broken down by ultraviolet radiation, releasing chlorine atoms. These chlorine atoms then react with ozone molecules, breaking them apart and depleting the ozone layer. This process is known as ozone depletion and has significant environmental consequences, such as increased UV radiation reaching the Earth's surface, which can lead to skin cancer, damage to marine life, and disruption of ecosystems.

Which of the followings processes acts to remove carbon dioxides from the atmosphere...?

Burning Fossil fuels
Photosynthesis
Deforestation
Lightning

Correct Answer

A. Photosynthesis

Explanation

Photosynthesis is the correct answer because it is a process by which green plants and some other organisms convert carbon dioxide and sunlight into glucose and oxygen. During photosynthesis, plants absorb carbon dioxide from the atmosphere and release oxygen as a byproduct. This process helps to remove carbon dioxide from the atmosphere and is essential for maintaining the balance of gases in the environment.

6.

Which one of the followings is biodegradable?

Plastic mug
Chips pockets
News paper
Aluminium foil

Correct Answer

A. News paper

Explanation

News paper is biodegradable because it is made from natural materials such as wood pulp, which can be broken down by bacteria and other microorganisms over time. This process allows the paper to decompose and return to the environment without causing long-term harm. On the other hand, plastic mug, chips pockets, and aluminium foil are not biodegradable and can persist in the environment for hundreds of years, contributing to pollution and environmental damage.

7.

Which is the threat to environment?

Growing Population
Growing forests
Conversing Wild life
None of the Above

Correct Answer

A. Growing Population

Explanation

Growing population is a threat to the environment because it leads to increased demand for resources such as land, water, and energy. This can result in deforestation, habitat destruction, pollution, and depletion of natural resources. The growing population also puts pressure on infrastructure, transportation, and waste management systems, leading to further environmental degradation. Therefore, the presence of a growing population poses significant challenges in maintaining a sustainable and healthy environment.

Which substance makes 78% of Air?

Oxygen
Carbon Dioxide
Water vapour
Nitrogen

Correct Answer

A. Nitrogen

Explanation

Nitrogen makes up 78% of air. Air is composed of various gases, and nitrogen is the most abundant gas, accounting for the majority of the air we breathe. Oxygen, carbon dioxide, and water vapor are also present in the air, but in smaller quantities compared to nitrogen.

Chipko Movement is related to....?

Forest conservation
Soil Conservation
Water Consevation
Wild life Conservation

Correct Answer

A. Forest conservation

Explanation

The Chipko Movement is a social and environmental movement that originated in India in the 1970s. It was primarily focused on the conservation of forests. The movement involved hugging or embracing trees to prevent them from being cut down, thus raising awareness about deforestation and the importance of preserving forests. The movement aimed to protect the environment, promote sustainable development, and safeguard the livelihoods of local communities dependent on the forests. Therefore, the correct answer is forest conservation.

The colour of the Taj Mahal changes from white to yellowish it is due to....?

Flood
Earthquake
Acid Rain
Depletion of Ozone layer

Correct Answer

A. Acid Rain

Explanation

The correct answer is Acid Rain. Acid rain is caused by pollutants in the air, such as sulfur dioxide and nitrogen oxide, which react with water molecules to form sulfuric acid and nitric acid. These acids can corrode and discolor the surface of buildings and structures, including the Taj Mahal. Over time, the acid rain can cause the white marble of the Taj Mahal to turn yellowish.
