There are several conflicting usages of geosphere, variously defined. It may be taken as the collective name for the lithosphere , the hydrosphere , the cryosphere , and the atmosphere . [ 1 ] The different collectives of the geosphere are able to exchange different mass and/or energy fluxes (the measurable amount of change).
Earth is the only known place that has ever been habitable for life. Earth's life developed in Earth's early bodies of water some hundred million years after Earth formed. Earth's life has been shaping and inhabiting many particular ecosystems on Earth and has eventually expanded globally forming an overarching biosphere. [242]
Life forms live in every part of the Earth's biosphere, including soil, hot springs, inside rocks at least 19 km (12 mi) deep underground, and at least 64 km (40 mi) high in the atmosphere. [26] [27] [28] Marine life under many forms has been found in the deepest reaches of the world ocean while much of the deep sea remains to be explored. [29]
The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
NASA true-color image of the Earth's surface and atmosphere. Physical geography (also known as physiography) is one of the two fields of geography. [1] [2] [3]Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the lithosphere, hydrosphere, atmosphere, pedosphere geosphere and global flora and fauna patterns ...
The whole mass of air surrounding the Earth, the density of the atmosphere decreases outward, which pushes the oxygen inward allowing humans to breathe without consequence. The general circulation of the atmosphere is defined as the zonally and temporally averaged wind and temperature fields.
Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the cryosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere).
The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator, [23] with some variation due
