Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Carbon gets into the lithosphere by
A
decomposition
B
cellular respiration
C
photosynthesis
D
combustion
Explanation: 

Detailed explanation-1: -Rocks also absorb carbon from the rain in a process called weathering that moves carbon into the lithosphere. Chemical weathering is initiated when acidic substances (ex. carbonic acid) come into contact with rocks. This process will break down the minerals in rocks into their component ions.

Detailed explanation-2: -When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals. Some of this sediment might form fossil fuels, such as coal, oil, or natural gas, which release carbon back into the atmosphere when the fuel is burned.

Detailed explanation-3: -Some carbon dioxide is released from the interior of the lithosphere by volcanoes. Carbon dioxide released by volcanoes enters the lower lithosphere when carbon-rich sediments and sedimentary rocks are subducted and partially melted beneath tectonic boundary zones.

Detailed explanation-4: -After death, decomposition releases carbon into the air, soil and water. Living things capture this liberated carbon to build new life.

Detailed explanation-5: -The lithosphere contains both inorganic carbon such as shale gas, coal, oil, gas and limestone, and organic carbon such as organic matter in soils and leaf litter.
