Atmosphere And Environment Quiz

2.

Greenhouse gases only bring harmful effects to the Earth.

True
False

Correct Answer

A. False

Explanation

Greenhouse gases help to keep the Earth at an optimum temperature by absorbing radiation from the sun, however when the carbon cycle is disrupted and more greenhouse gases are emitted, it will cause global warming

3.

Which of these is not a greenhouse gas?

Carbon dioxide
Oxygen
Methane
Sulfur dioxide

Correct Answer

A. Oxygen

Explanation

Oxygen is not a greenhouse gas because it does not trap heat in the Earth's atmosphere. Greenhouse gases, such as carbon dioxide, methane, and sulfur dioxide, have the ability to absorb and emit infrared radiation, leading to the greenhouse effect. Oxygen, on the other hand, is a vital component of the Earth's atmosphere, but it does not contribute to the greenhouse effect.

4.

Which of these is not a way where carbon monoxide is formed?

Wood stoves
Tobacco smoke
Lightning activities
Leaing chimneys and furnaces

Correct Answer

A. Lightning activities

Explanation

Carbon monoxide is not formed through lightning activities. Carbon monoxide is primarily produced by the incomplete combustion of carbon-containing fuels, such as wood stoves, chimneys, furnaces, and tobacco smoke. Lightning activities, on the other hand, generate high temperatures and energy, but they do not involve the combustion of carbon-based materials, making it an incorrect option.

5.

Which of these is false?

Sulfur dioxide and nitrogen dioxide causes respiratory problems which may lead to cancer or respiratory illnesses.
When acidic rain gets onto buildings and structures, they help to polish the surface.
When acidic rain seeps through the soils, it acidifies the soil, which in turn destroy plants growing on the acidic soil.
When acidic rain gets into water bodies, it changes the pH of the water, causing aquatic life to die as the environment is too acidic.

Correct Answer

A. When acidic rain gets onto buildings and structures, they help to polish the surface.

Explanation

Acidic rain is formed when sulfur dioxide and nitrogen dioxide react with water vapor in the atmosphere. It is a form of pollution that can have harmful effects on the environment and living organisms. When acidic rain falls on buildings and structures, it can actually cause damage to the surface rather than polishing it. The acid in the rain can corrode and deteriorate materials such as metal, stone, and paint, leading to degradation and a loss of structural integrity. Therefore, the statement that acidic rain helps to polish surfaces is false.

What is usually the colour of photochemical smog?

White
Black
Brown
Purple

Correct Answer

A. Brown

Explanation

Photochemical smog is typically brown in color. This is caused by the reaction of sunlight with pollutants such as nitrogen oxides and volatile organic compounds in the atmosphere. These reactions produce a mixture of different compounds, including ozone and various particulate matter, which give the smog its brownish appearance. The brown color is often associated with hazy and polluted air in urban areas.

7.

Which of these is not a property of ozone?

It is a greenhouse gas.
It forms the ozone layer which absorbs and blocks harmful radiation of the sun into the Earth.
Each ozone molecule is made up of 2 oxygen molecules
It helps to keep the Earth warm

Correct Answer

A. Each ozone molecule is made up of 2 oxygen molecules

Explanation

Ozone is a molecule composed of three oxygen atoms, not two oxygen molecules. Each ozone molecule contains three oxygen atoms bonded together, giving it the chemical formula O3. This is different from regular oxygen molecules, which consist of two oxygen atoms bonded together, with the chemical formula O2. Therefore, the statement "Each ozone molecule is made up of 2 oxygen molecules" is not a property of ozone.

8.

What is CFC?

Carbonoxyfluorochlorides
Carbon-fluoride-carbon
Chlorofluorocarbon
Chloricfluoricarbon

Correct Answer

A. Chlorofluorocarbon

Explanation

CFC stands for chlorofluorocarbon, which is a compound that contains chlorine, fluorine, and carbon atoms. These compounds were commonly used in the past as refrigerants, propellants, and solvents. However, they have been found to contribute to the depletion of the ozone layer and are now regulated and phased out in many countries.

9.

Living things contain carbon.

True
False

Correct Answer

A. True

Explanation

Living things contain carbon because carbon is a fundamental element in the structure of organic molecules, such as proteins, carbohydrates, lipids, and nucleic acids, which are essential for life. Carbon atoms have the unique ability to form stable bonds with other carbon atoms and with other elements, allowing for the vast diversity and complexity of biological molecules. Therefore, it is true that living things contain carbon.

10.

Living things are a part of the carbon cycle.

True
False

Correct Answer

A. True

Explanation

Living things are a part of the carbon cycle because they play a crucial role in both the uptake and release of carbon dioxide. Through the process of photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into organic compounds, releasing oxygen as a byproduct. When animals consume plants or other animals, they obtain carbon compounds, which are broken down during respiration, releasing carbon dioxide back into the atmosphere. This continuous exchange of carbon between living organisms and the atmosphere is a fundamental aspect of the carbon cycle.

11.

Which of these is not part of the carbon cycle?

Respiration of humans
Photosynthesis
Decaying of animals
Emission from cars
None of the above

Correct Answer

A. None of the above

Explanation

All of the options listed in the question are actually part of the carbon cycle. The carbon cycle is the process by which carbon is exchanged between the atmosphere, oceans, and living organisms. Respiration of humans releases carbon dioxide, photosynthesis takes in carbon dioxide and releases oxygen, decaying of animals releases carbon back into the environment, and emissions from cars release carbon dioxide into the atmosphere. Therefore, none of the options listed are not part of the carbon cycle.

Which of these is not an impact of global warming?

A rise in sea level
Desert area will increase
The Earth will become colder
Melting of ice caps

Correct Answer

A. The Earth will become colder

Explanation

Global warming refers to the increase in the Earth's average temperature due to the release of greenhouse gases. As a result of global warming, several impacts occur, such as a rise in sea level, an increase in desert areas, and the melting of ice caps. However, the statement that the Earth will become colder is incorrect. Global warming leads to a warming effect on the Earth, causing higher temperatures and climate changes.
