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).
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
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 ...
Coastal geography is the study of the dynamic interface between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, geology, and oceanography) and the human geography of the coast.
The layer of an ecosphere that exists as a gas. The atmosphere is the most distant component sphere of matter from the planet's Center of mass, beyond which is Outer space. 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.
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.
Earth's surface is the boundary between the atmosphere, and the solid Earth and oceans. Defined in this way, it has an area of about 510 million km 2 (197 million sq mi). [12] Earth can be divided into two hemispheres: by latitude into the polar Northern and Southern hemispheres; or by longitude into the continental Eastern and Western hemispheres.
