Detailed explanation-1: -Carbon is the foundation of all life on Earth, required to form complex molecules like proteins and DNA. This element is also found in our atmosphere in the form of carbon dioxide (CO2).
Detailed explanation-2: -In the atmosphere, carbon exists primarily in the form of carbon dioxide (CO2) and methane gas (CH4).
Detailed explanation-3: -Carbon dioxide mixes evenly through the atmosphere. But the atmosphere as a whole is densest near the ground, so a cubic foot of air at ground level will contain more carbon dioxide molecules than a cubic foot of air high up in the sky.
Detailed explanation-4: -Carbon occurs naturally as anthracite (a type of coal), graphite, and diamond. More readily available historically was soot or charcoal. Ultimately these various materials were recognised as forms of the same element.
