LIFE SCIENCE

Detailed explanation-1: -Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

Detailed explanation-2: -Carbonic acid in the rain falls into bodies of water moving carbon into the hydrosphere. Rocks also absorb carbon from the rain in a process called weathering that moves carbon into the lithosphere.

Detailed explanation-3: -Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.

Detailed explanation-4: -1) Trees and Forests Plants remove carbon dioxide from the air naturally, and trees are especially good at storing CO2 removed from the atmosphere by photosynthesis.
