Question

The main consequence of the many cycles of Earth, such as the life cycle, biogeochemical, and geochemical cycles, is _____.

1.keeping the earth running and moving
2.keeping us alive
3.maintaining a balance or equilibrium on Earth
4.adding and removing Earth materials and chemicals

Answer 1

maintaining a balance or equilibrium on Earth

Answer 2

The correct answer is option 3, that is, maintaining a balance or equilibrium on Earth.

The biogeochemical cycle refers to the natural passages by which the important elements of living matter are circulated. The most essential biogeochemical cycles are the nitrogen cycle, carbon cycle, phosphorus cycle, oxygen cycle, and the water cycle. A geochemical cycle refers to the passageway, which is taken by the chemical constituents in the crust and the surface of the Earth.

The biogeochemical and the geochemical cycles always possess a condition of evenness. The state of symmetry takes place when there is a steadiness in the cycling of the elements among the segments.
