- Black carbon (BC) is a component of fine particulate matter. Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emitted in anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality.
- In climatology, black carbon is a climate forcing agent. Black carbon warms the Earth by absorbing sunlight and heating the atmosphere and reducing albedo when deposited on snow and ice.
- Black carbon stays in the atmosphere for only several days to weeks, whereas carbon dioxide (CO 2) has an atmospheric lifetime of more than 100 years.
- The term black carbon is also used in soil sciences and geology. Especially in the tropics, black carbon in soils significantly contributes to fertility as it can absorb important plant nutrients.

Explanation:
Black carbon is a fine particulate matter component that is formed through the incomplete combustion of fossil fuels, biofuel, and biomass. It is released into the atmosphere from various sources such as industrial activities, vehicular emissions, and the burning of solid fuels for cooking and heating.
Statement 1: Black carbon is a fine particulate matter component, formed through the incomplete combustion of fossil fuels, biofuel, and biomass.
This statement is correct as black carbon is indeed formed through the incomplete combustion of these substances. Incomplete combustion occurs when there is insufficient oxygen for complete oxidation, resulting in the production of black carbon particles.
Statement 2: Black carbon increases the albedo when deposited on snow and ice.
This statement is incorrect. Black carbon actually reduces the albedo when deposited on snow and ice. Albedo refers to the reflectivity of a surface, with higher albedo indicating more reflectivity. When black carbon particles are deposited on snow and ice, they absorb sunlight and reduce the reflectivity of the surface, leading to increased melting and warming.
Statement 3: In the tropics, black carbon in soils significantly contributes to soil fertility.
This statement is correct. Black carbon, when present in soils, can contribute to soil fertility. It acts as a nutrient reservoir, helping to retain and release essential plant nutrients. Additionally, black carbon can improve soil structure, water holding capacity, and microbial activity, all of which enhance soil fertility.
Therefore, the correct statements are 1 and 3.
