Consider the following statements regarding permafrost: It is def...
Statement 1: It is defined solely based on temperature and duration.
Permafrost is a type of ground that remains at or below 0 degrees Celsius for at least two consecutive years. It is defined based on both temperature and duration. Therefore, statement 1 is correct.
Statement 2: It contains large quantities of organic leftover from thousands of years.
Permafrost is composed of a mixture of soil, rock, and ice. It can contain large quantities of organic material, such as dead plants and animals, that have been preserved for thousands of years due to the cold temperatures. Therefore, statement 2 is correct.
Statement 3: In the northern hemisphere, it is found in higher latitudes only.
Permafrost is found in both the northern and southern hemispheres, but it is more extensive in the northern hemisphere. It is commonly found in regions with high latitudes and cold climates, such as the Arctic and sub-Arctic regions. Therefore, statement 3 is incorrect.
Statement 4: Thawing of permafrost is a major contributor to climate change.
Thawing of permafrost can indeed contribute to climate change. When permafrost thaws, it releases large amounts of greenhouse gases, primarily carbon dioxide and methane, into the atmosphere. These greenhouse gases can trap heat and contribute to the warming of the Earth's climate. Therefore, statement 4 is correct.
Based on the analysis above, we can conclude that statements 1, 2, and 4 are correct. Therefore, the correct answer is option 'B' (1, 2, and 4 only).

Option b is correct.
- Statement 1 is correct: Permafrost is a ground that remains completely frozen at 0 degrees Celsius or below for at least two years. It is defined solely based on temperature and duration.
- Statement 2 is correct: Beneath its surface, permafrost contains large quantities of organic leftover from thousands of years prior — dead remains of plants, animals, and microorganisms that got frozen before they could rot. It also holds a massive trove of pathogens.
- Statement 3 is incorrect: These grounds are known to be below 22 per cent of the land surface on Earth, mostly in polar zones and regions with high mountains. They are spread across 55 per cent of the landmass in Russia and Canada, 85 per cent in the US state of Alaska, and possibly the entirety of Antarctica. At lower latitudes, permafrost is found at high altitude locations such as the Alps and the Tibetan plateau. Thus, in Northern Hemisphere, Permafrost is not confined to higher latitudes only.
- Statement 4 is correct: When permafrost thaws, microbes start decomposing this carbon matter, releasing greenhouse gases like methane and carbon dioxide. Researchers have estimated that for every 1-degree Celsius rise in average temperature, permafrost regions could release greenhouse gases to the tune of 4-6 years of emissions from coal, oil, and natural gas — becoming a major factor of climate change in themselves.
