1.

Methane is not a greenhouse gas
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Methane is indeed a greenhouse gas. It is released into the atmosphere through various human activities such as agriculture, fossil fuel extraction, and waste management. Methane has a high global warming potential and contributes significantly to climate change. Therefore, the statement that methane is not a greenhouse gas is false.

2.

Methane is odourless and colourless
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Methane is actually odorless but not colorless. It is a colorless gas, but it has a distinct odor that is often described as being similar to rotten eggs. This odor is added to methane gas for safety reasons, as it helps to detect leaks and prevent accidents. Therefore, the given statement is false.

3.

Global warming is caused by methane
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Global warming is caused by methane because methane is a potent greenhouse gas that traps heat in the Earth's atmosphere. When released into the atmosphere, methane absorbs and radiates heat, contributing to the greenhouse effect and leading to an increase in global temperatures. Methane is released through various human activities such as agriculture, fossil fuel extraction, and waste management. It is important to address methane emissions as part of efforts to mitigate global warming and climate change.

Name some effects of global warming

Correct Answer
disrupting crop growth
desertification
increased rainfall
flooding

Explanation
Global warming has several effects on the environment. One of these effects is disrupting crop growth, as rising temperatures and changing weather patterns can negatively impact agricultural productivity. Another effect is desertification, where arid areas expand due to increased evaporation and decreased rainfall. Additionally, global warming can lead to increased rainfall in certain regions, which can result in flooding. These effects of global warming highlight the significant impact it has on various aspects of the ecosystem, including agriculture and natural habitats.

Global warming _________ the temperature.
- A.
  
  Increase
- B.
  
  Decrease
- C.
  
  Maintains
Correct Answer
A. Increase

Explanation
Global warming refers to the long-term increase in Earth's average temperature. Therefore, it is logical to conclude that global warming causes an increase in temperature.
