Which is not a major biogeochemical cycle?

oxygen cycle

carbon cycle

nitrogen cycle

atmosphere cycle

An atmospheric cycle is not a major biogeochemical cycle.

Explanation:

The flow of air from the high-pressure area to the low-pressure area is called the atmosphere cycle. Low-pressure areas are created by the upliftment of the heated air. Higher and colder atmosphere will fall eventually by creating a high-pressure area.

Monsoon patterns are the result of these atmosphere cycles. The weather in high-pressure areas is stable with clear skies compared to low-pressure areas where weather is highly unstable with clouds (formed from vapour due to the higher temperature).  

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
