With reference to Methane, consider the following statements:1. It is ...
Correct Answer: c) All three
One of the statements provided is indeed correct, while the other two are inaccurate. Let's break down each statement to understand why:
- Methane is a short-lived greenhouse gas: This statement is correct. Methane is considered a short-lived greenhouse gas compared to carbon dioxide. It has a shorter atmospheric lifespan but is significantly more potent in trapping heat, contributing to global warming.
- Methane is a colorless, odorless, and flammable water-insoluble gas: This statement is also accurate. Methane is indeed colorless and odorless, making it difficult to detect without specialized equipment. Additionally, it is flammable and does not dissolve in water.
- Methane leads to ground-level ozone pollution: This statement is incorrect. While methane itself does not directly lead to ground-level ozone pollution, its reactions in the atmosphere can contribute to the formation of ozone, which is a harmful air pollutant.
In conclusion, two out of the three statements provided are correct. Methane is a short-lived greenhouse gas that is colorless, odorless, and flammable. However, it does not directly lead to ground-level ozone pollution.

- The largest sources of methane are agriculture, fossil fuels, and decomposition of landfill waste.
- Impacts
- It harms human and ecosystem health.
- Its emissions lead to ground-level ozone pollution which causes approximately a million premature deaths per year globally and reduces crop productivity and harms ecosystems.
Key facts about Baltic Sea
- It is a semi-enclosed inland sea located in Northern Europe.
