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 atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
Oceans cover almost three quarters (71%) of the surface of the Earth, and nearly half of the world's marine waters are over 3000 m deep. This global, interconnected body of salt water , called the World Ocean, is divided by the continents and archipelagos into the following five bodies, from the largest to the smallest: the Pacific Ocean , the ...
Physical geography (also known as physiography) is one of the three main branches of geography. [1] [2] [3] [4] [5] Physical geography is the branch of natural ...
Cryosphere – Those portions of Earth's surface where water is in solid form; Geosphere/Solid Earth – (Also sometimes a collective name for the lithosphere, the hydrosphere, the cryosphere, and the atmosphere) The union of all solid parts of Earth and the Inner of Earth.
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 atmosphere envelops the earth and extends hundreds of kilometres from the surface. It consists mostly of inert nitrogen (78%), oxygen (21%) and argon (0.9%). [4] Some trace gases in the atmosphere, such as water vapour and carbon dioxide, are the gases most important for the workings of the climate system, as they are greenhouse gases which allow visible light from the Sun to penetrate to ...
The composition of Earth's atmosphere is determined by the by-products of the life that it sustains. Dry air (mixture of gases) from Earth's atmosphere contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and traces of hydrogen, helium, and other "noble" gases (by volume), but generally a variable amount of water vapor is ...
