Questions and Answers

1.

Which of the following is a greenhousegas?
- A.
  
  Carbonic acid
- B.
  
  Carbon dioxide
- C.
  
  Carbon monoxide
- D.
  
  Nitrous dioxide
Correct Answer
B. Carbon dioxide

Explanation
Carbon dioxide is a greenhouse gas because it is able to trap heat in the Earth's atmosphere. This occurs through a process known as the greenhouse effect, where certain gases in the atmosphere absorb and re-emit infrared radiation, preventing it from escaping into space. Carbon dioxide is a major contributor to the greenhouse effect due to its high concentration in the atmosphere and its ability to absorb and re-emit infrared radiation effectively. This leads to an increase in the Earth's temperature, causing global warming and climate change.

Which is the greenhouse gas among the following?
- A.
  
  Nitrogen
- B.
  
  Oxygen
- C.
  
  Carbon monoxide
- D.
  
  Methane
Correct Answer
D. Methane

Explanation
Methane is the greenhouse gas among the options provided. Greenhouse gases are gases that trap heat in the Earth's atmosphere, contributing to the greenhouse effect and global warming. Methane is a potent greenhouse gas, with a much higher warming potential than carbon dioxide. It is released through natural processes like the decomposition of organic matter and human activities such as livestock farming and the production and transport of coal, oil, and gas.

_____________ can cause global warming.
- A.
  
  Fish swimming
- B.
  
  Trees growing
- C.
  
  Volcanoes
- D.
  
  Mudslides
Correct Answer
C. Volcanoes

Explanation
Volcanoes can cause global warming due to the release of greenhouse gases such as carbon dioxide and methane during volcanic eruptions. These gases trap heat in the atmosphere, leading to an increase in global temperatures. Additionally, volcanic eruptions can release aerosols and ash into the atmosphere, which can reflect sunlight back into space and have a cooling effect in the short term, but can also contribute to global warming in the long term.

____________________ can cause global warming.
- A.
  
  Forest fires
- B.
  
  Trees growing
- C.
  
  Solar panels
- D.
  
  Hydropower
Correct Answer
A. Forest fires

Explanation
Forest fires can cause global warming because they release large amounts of carbon dioxide and other greenhouse gases into the atmosphere. When trees and vegetation burn, they release stored carbon, which combines with oxygen to form carbon dioxide. This increase in carbon dioxide levels contributes to the greenhouse effect, trapping heat in the Earth's atmosphere and leading to global warming. Forest fires also release other pollutants such as black carbon, which can further contribute to climate change.

________________ can cause global warming.
- A.
  
  Butterflies
- B.
  
  Using too much solar power
- C.
  
  Livestock
- D.
  
  Planting too many trees
Correct Answer
C. Livestock

Explanation
Livestock can cause global warming due to their production of greenhouse gases, particularly methane. Methane is a potent greenhouse gas that is released through the digestive process of ruminant animals like cows and sheep. The large-scale farming of livestock leads to significant methane emissions, contributing to the greenhouse effect and global warming. Additionally, livestock farming also requires deforestation for grazing land and the production of animal feed, further exacerbating the environmental impact.

Humans burn______________ fuels which can add greenhouse gases.
- A.
  
  Energy
- B.
  
  Fossil
- C.
  
  Carbonic
- D.
  
  Liquid
Correct Answer
B. Fossil

Explanation
Humans burn fossil fuels, such as coal, oil, and natural gas, for various purposes like generating electricity, transportation, and heating. When these fossil fuels are burned, they release greenhouse gases, such as carbon dioxide, into the atmosphere. These greenhouse gases contribute to the greenhouse effect, trapping heat in the Earth's atmosphere and leading to global warming and climate change. Therefore, burning fossil fuels is a significant source of greenhouse gas emissions.

What is the greenhouse effect?
- A.
  
  Where heat is kept out of the atmosphere
- B.
  
  Where heat is retained in the atmosphere
- C.
  
  Where more light is let into the atmosphere
- D.
  
  Where less light is let into the atmosphere
Correct Answer
B. Where heat is retained in the atmosphere

Explanation
The greenhouse effect refers to the process by which heat is trapped and retained in the Earth's atmosphere. This occurs when certain gases, such as carbon dioxide and methane, absorb and re-emit infrared radiation, preventing it from escaping into space. This phenomenon is essential for maintaining the Earth's temperature and making it habitable for life.

What could one effect of global warming be?
- A.
  
  More islands forming
- B.
  
  Sea level rise
- C.
  
  More volcanic eruptions
- D.
  
  More landslides
Correct Answer
B. Sea level rise

Explanation
One effect of global warming could be sea level rise. As the Earth's temperature increases, ice caps and glaciers melt, causing an increase in the volume of water in the oceans. This leads to a rise in sea levels, which can result in coastal flooding, erosion, and the displacement of coastal communities. The melting of ice also contributes to the warming of the oceans, further exacerbating the effects of global warming.

What do greenhouse gases do?
- A.
  
  They cause more heat to be kept out of the Earth.
- B.
  
  They cause the sun's light to be kept out of the Earth
- C.
  
  They absorb and hold in heat.
- D.
  
  They cause acid rain.
Correct Answer
C. They absorb and hold in heat.

Explanation
Greenhouse gases, such as carbon dioxide and methane, have the ability to absorb and trap heat in the Earth's atmosphere. This process is known as the greenhouse effect. When sunlight enters the atmosphere, some of it is reflected back into space, while greenhouse gases absorb and re-radiate a portion of the heat, preventing it from escaping. This trapped heat warms the Earth's surface and contributes to climate change. Therefore, the correct answer is that greenhouse gases absorb and hold in heat.

Global warming itself could cause.
- A.
  
  Forest fires
- B.
  
  Glaciers to get smaller
- C.
  
  Glaciers to grow
- D.
  
  Volcanoes to erupt
Correct Answer
B. Glaciers to get smaller

Explanation
Global warming is the increase in Earth's average temperature due to human activities, primarily the emission of greenhouse gases. As global temperatures rise, the effects on glaciers are significant. The warmer temperatures cause the ice in glaciers to melt at a faster rate than it can accumulate, resulting in the overall reduction in glacier size. This is supported by scientific evidence and observations of shrinking glaciers in various parts of the world. Therefore, the correct answer is glaciers to get smaller.
