Which of the following is essential for life on earth? select all that apply.
biogeochemical cycles
climate cycling
volcanic cycling
geochemical cycling

Everything that is on that list.

If we didn't have any of those then life on Earth would no exist. We need everything to exist on Earth

Option (1), (2) and (3)

Explanation:

Biogeochemical cycle refers to the transfer of chemical matter from the biotic to abiotic components of earth. The biotic components includes the living beings, and the abiotic components includes the the hydrosphere, lithosphere and atmosphere. These chemical matters contains the elements such as hydrogen, oxygen, carbon, calcium, nitrogen and so on. This, cycle maintains the existence of life on earth.

The climate and volcanic cycle are also equally important because life is difficult to survive in an extreme hot or cold weather condition. The climate in any particular area gets affected because of the release of the excess amount of green house gases, volcanic activities and some other factors. The excess amount of green house gas causes the earth's global temperature to rise and thereby the ice and the glaciers in the polar region and high altitude mountains gets melt. The volcanic eruptions ejects lava that solifies and forms rock where life can occur after several thousands of years, but it also affect the climate because it releases a huge amount of toxic gases that bring about negative changes to the atmosphere. As a result of which, life gets affected on earth.

The geochemical cycle involves the changes in the composition of rocks due to the presence or absence of different chemical elements along with the changing temperature and pressure condition. Life is not related to it.

Thus, life is dependent on the following cycles, namely the biogeochemical, the climate and the volcanic cycle.

Hence, the correct answer is option (1), (2) and (3).

Adenine pairs with Thymine because they have a bondage of two hydrogen bonds . Cytosine pairs with guanine because they have three nitrogen bonds. These pairs allow protein synthesis and DNA replication to occur
