Definition of the Environment

The environment consists of four overlapping components, which play a vital role in sustaining life on Earth. The four components are the Atmosphere, Lithosphere, Hydrosphere and Biosphere each works hand in hand with each other, without one of these components this would upset the delicate balance of the environment.

The atmosphere is a mixture of transparent and odorless gases, which is surrounding the earth in a layer, which is held in place by the Earth gravitational pull.

The lithosphere is the Earth’s solid shell, which is constantly changing, some changes occur dramatically whilst other may take millions of years to form.

The Hydrosphere is the interconnected system of water storage in the atmosphere and lithosphere.

The biosphere the surface zone of the Earth and its adjacent atmosphere, in which all organic life exists.

Interaction of the Environments Components

The Environments components all work together, each one some how is connected to the other components some how.

HYDROSPHERE is connected to the:

Atmosphere: Water is transferred between the hydrosphere and biosphere by evaporation and precipitation.

Biosphere: plants withdraw water from the ground using their root systems and transport water and nutrients through to stems and leaves. Evaporation of water from the leaf surface is effective at transferring water to the atmosphere.

Lithosphere: Water is the primary agent for the chemical and mechanical breakdown of rock, called weathering, to form loose rock fragments and soil. By the process of erosion, water sculpts the surface of the Earth.

ATMOSPHERE is connected to the:

Hydrosphere: When the gases of the atmosphere come together with dissolved gases in water through a process known as gas exchange.

Biosphere: it works by the exchanges of carbon dioxide and oxygen between the biosphere and atmosphere.

Lithosphere: Volcanic eruptions emit gases to the atmosphere and atmospheric carbon dioxide dissolves in rainwater to produce a weak acid which is important for the breakdown (weathering) or rock exposed at the Earth surface.

BIOSPHERE is connected to the:

Atmosphere: Life processes involve a vast number of chemical reactions some of which either extract or emit gases from and to the atmosphere. For example, photosynthesis consumes carbon dioxide and produces oxygen whereas respiration does the opposite.

Hydrosphere: Water is essential for all living organisms on Earth and has played a key role in the evolution and sustenance of life on our planet. The biosphere as we know it would not exist without liquid water. Water is also important for transport the soluble nutrients that are needed for plant growth, and for transporting the waste products of life’s chemical reactions.

Lithosphere: The Lithosphere and biosphere are intimately connected through soils, which consist of a mixture of air, mineral matter, organic matter, and water. In fact, one could consider soil as composed of all four spheres.

LITHOSPHERE is connected to the:

Atmosphere: Each year volcanoes spew significant amounts of gases into the atmosphere. When this happens the Atmosphere tries to filter the gases from the eruption.

Hydrosphere: Water is the main agent of chemical and mechanical erosion of the earth surface. When water flows over land it mechanically breaks rocks into finer particles and can chemically dissolve elements contained in rock-forming minerals

Biosphere: The weathering of the lithosphere to form soils provides plants with a firm substrate and vital nutrients and minerals needed for plant growth.

The term `Bio-diversity’ is indeed commonly used to describe the number, variety and variability of living organisms. This basically means Life on Earth.

Perception of the Environment

Some factors that affect people ’s perception of the environment, are that it’s is something that we can make money off, also when we get these resource they sometimes can have a damaging effect on the Earth’s environment and that the Earth can’t regenerate all of its resources.

For years Man has been exploiting the mineral resources of the lithosphere by mining of raw materials. For example, the mining and subsequent combustion of fossil fuels represents a transfer of carbon from the lithosphere to the atmosphere. By this process, man has accelerated the natural rate of transfer of carbon dioxide from the lithosphere to the atmosphere. In turn, the increased concentration of carbon dioxide in the atmosphere will lead to global warming by enhancing the greenhouse effect.

Biosphere - Term Paper

Biosphere

Biosphere is defined as that part of the earth and atmosphere in which many smaller ecosystems exist and operate. Three main subdivisions of the biosphere are lithosphere (solid matter); hydrosphere (liquid matter), and atmosphere or the gaseous envelope of the earth which extends up to a height of 22.5 km. The area of contact and interaction between these components is really important for life, for it is here that the entire life is confined and the basic processes of life like photosynthesis and respiration occur.

Living organisms are, mostly, confined to the parts of biosphere that receive solar radiation during the day. As stated above this includes atmosphere, the surface of land, the few meters of soil and the upper layers of water of oceans, lakes and rivers. The illuminated zone may be a few centimeters in turbid water of a river, and up to about 100 meters in clearest part of an ocean. In the ocean, the biosphere does not end where light ceases as gravity enables the energy flow to continue downward, since fecal pellets, cast skins and organisms dead and alive are always falling from the illuminated regions into the depths.

In addition to the extension of the biosphere downwards, there is a limited extension upwards also. On very high mountains, like Himalayas, the limit above which chlorophyll-bearing plants cannot live appears to be about 6,200 meters.

In simple words, biosphere can be viewed as the part of the earth consisting of oceans and the surface of the continents, together with the adjacent atmosphere (i.e. the troposphere). However, polar ice caps and the higher mountains slopes above the snow line are known as parabiosphere.

Since living organisms require inorganic metabolites from each of the subdivision of the biosphere, water from the hydrosphere, mineral from lithosphere and chemical elements from atmosphere, a brief discussion on.

Biosphere

The biosphere is the broadest level of ecological study, the global sum of all ecosystems. From the broadest biophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere. hydrosphere. and atmosphere. This biosphere is postulated to have evolved. beginning through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.

Origin and use of the term

The term "biosphere" was coined by geologist Eduard Suess in 1875, which he defined as: [Seuss, E. (1875) "Die Entstehung Der Alpen" ["The Origin of the Alps"]. Vienna: W. Braunmuller. ]

quote|"the place on earth's surface where life dwells."

While this concept has a geological origin, it is an indication of the impact of both Darwin and Maury on the earth sciences. The biosphere's ecological context comes from the 1920s ("see" Vladimir I. Vernadsky ), preceding the 1935 introduction of the term " ecosystem " by Sir Arthur Tansley (see ecology history). Vernadsky defined ecology as the science of the biosphere. It is an interdisciplinary concept for integrating astronomy. geophysics. meteorology. biogeography. evolution. geology. geochemistry. hydrology and, generally speaking, all life and earth sciences.

Some life scientists and earth scientists use "biosphere" in a more limited sense. For example, geochemists define the biosphere as being the total sum of living organisms (the "biomass " or "biota " as referred to by biologists and ecologists). In this sense, the biosphere is but one of four separate components of the geochemical model, the other three being " lithosphere ", " hydrosphere ", and "atmosphere ". The narrow meaning used by geochemists is one of the consequences of specialization in modern science. Some might prefer the word "ecosphere", coined in the 1960s, as all encompassing of both biological and physical components of the planet.

The Second International Conference on Closed Life Systems defined biospherics as the science and technology of analogs and models of Earth 's biosphere; i.e. artificial Earth-like biospheres. Others may include the creation of artificial non-Earth biospheres — for example, human-centered biospheres or a native Martian biosphere — in the field of biospherics.

The concept that the biosphere is itself a living organism, either actually or metaphorically, is known as the Gaia hypothesis .

James Lovelock. an atmospheric scientist from the United Kingdom, proposed the Gaia hypothesis to explain how biotic and abiotic factors interact in the biosphere. This hypothesis considers Earth itself a kind of living organism. Its atmosphere, geosphere, and hydrosphere are cooperating systems that yield a biosphere full of life. in the early 1970s, Lynn Margulis. a microbiologist from the United States, added to the hypothesis specifically noting the ties between the biosphere and other Earth systems. For example, when carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continue, they remove more and more carbon dioxide from the atmosphere.

Many scientists are now devoting their careers to organizing new fields of study, such as geobiology and geomicrobiology. to examine these intriguing relationships .

Extent of Earth's biosphere

Nearly every part of the planet, from the polar ice caps to the Equator. supports life of some kind. Recent advances in microbiology have demonstrated that microbes live deep beneath the Earth's terrestrial surface, and that the total mass of microbial life in so-called "uninhabitable zones" may, in biomass, exceed all animal and plant life on the surface. The actual thickness of the biosphere on earth is difficult to measure. Birds typically fly at altitudes of 650 to 2000 meters, and fish that live deep underwater can be found down to -8,372 meters in the Puerto Rico Trench. [cite book | last = Campbell | first = Neil A. | authorlink = | coauthors = Brad Williamson; Robin J. Heyden | title = Biology: Exploring Life | publisher = Pearson Prentice Hall | date = 2006 | location = Boston, Massachusetts | pages = | url = http://www.phschool.com/el_marketing.html | doi = | id = | isbn = 0-13-250882-6 ]

There are more extreme examples for life on the planet: Rüppell's Vulture has been found at altitudes of 11,300 meters; Bar-headed Geese migrate at altitudes of at least 8,300 meters (over Mount Everest ); Yaks live at elevations between 3,200 to 5,400 meters above sea level; mountain goats live up to 3,050 meters. Herbivorous animals at these elevations depend on lichens, grasses, and herbs but the biggest tree is the Tine palm or mountain coconut found 3,400 meters above sea level.

Microscopic organisms live at such extremes that, taking them into consideration puts the thickness of the biosphere much greater. Culturable microbes have been found in the Earth's upper atmosphere as high as 41km (Wainwright et al, 2003, in FEMS Microbiology Letters). It is unlikely, however, that microbes are active at such altitudes, where temperatures and air pressure are extremely low and ultraviolet radiation very high. More likely these microbes were brought into the upper atmosphere by winds or possibly volcanic eruptions. Barophilic marine microbes have been found at more than 10km depth in the Marianas Trench (Takamia et al, 1997, in FEMS Microbiology Letters). Microbes are not limited to the air, water or the Earth's surface. Culturable thermophilic microbes have been extracted from cores drilled more than 5km into the Earth's crust in Sweden (Gold, 1992, and Szewzyk, 1994, both in PNAS), from rocks between 65-75C. Temperature increases rapidly with increasing depth into the Earth's crust. The speed at which the temperature increases depends on many factors, including type of crust (continental vs. oceanic), rock type, geographic location, etc. The upper known limit of microbial is 122C (" Methanopyrus kandleri " Strain 116), and it is likely that the limit of life in the "deep biosphere" is defined by temperature rather than absolute depth.

Our biosphere is divided into a number of biome s, inhabited by broadly similar flora and fauna. On land, biomes are separated primarily by latitude. Terrestrial biomes lying within the Arctic and Antarctic Circle s are relatively barren of plant and animal life, while most of the more populous biomes lie near the equator. Terrestrial organisms in temperate and Arctic biomes have relatively small amounts of total biomass, smaller energy budgets, and display prominent adaptations to cold, including world-spanning migrations, social adaptations, homeothermy. estivation and multiple layers of insulation.

When the word "Biosphere" is followed by a number, it is usually referring to a specific system. Thus:
* Biosphere 1 - The planet Earth
* Biosphere 2 - A laboratory in Arizona which contains 3.15 acres (13,000 m²) of closed ecosystem.
* BIOS-3 was a closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Siberia, in what was then the Soviet Union.

Biosphere Essay Research Paper The biosphere is

Biosphere Essay Research Paper

The biosphere is part of the earth in which life exists. It is 20 km thick from

the bottom of the ocean to the lower atmosphere. It consists of three layers:

the lithosphere which is the land on the surface of the earth; the hydrosphere

which comprises of the water on the earth as well as water vapor in the air; and

the atmosphere which is made up of the air that surrounds the earth. The living

organisms in the biosphere interact and affect each other in many ways. This is

called a biotic factor. Similarly there are non-living elements that have an

effect on living organisms these are considered abiotic factors. Examples of

abiotic factors are air temperature water soil light and minerals. In a

biosphere organisms live in special groupings. For instance a population

consists of all individuals of a species living in a general area. A community

is a population located in a certain area living among different species. An

ecosystem is yet a larger conglomeration of a population a community and

abiotic factors. Ecosystems can be aquatic or terrestrial. The earth’s aquatic

ecosystem makes up about 75% of the earth’s surface. This aquatic environment is

divided into marine and freshwater environments. The earth’s terrestrial

ecosystem is mainly made up of forests and deserts which make up for 25% of the

earth’s surface. The role or function of an organism in a community is that

organism’s niche. An organism’s niche is an area picked by that organism based

on physical factors such as temperature light oxygen and carbon dioxide

content and biological factors such as food competition for resources and

predators. This niche provides the organism a place to live in. A habitat

remains consistent with an organism’s niche as well as provides the organism

with a place to reproduce. In this case organisms may have the same habitat

but different niches. There are three types of relationships involving the

interactions between organisms. They are mutualism commensalism and

parasitism. Mutualism is a relationship where both organisms benefit from their

interaction with each other. An example is the honey bee and a flowering plant.

Commensalism only benefits one organism but the other organism is not affected.

Parasitism only benefits one organism and harms the other organism which most

of the time is the host. In the ecosystem matter and nutrients are cycled via

biogeochemical cycles such as water carbon dioxide nitrogen and phosphorous.

The burning of fossil fuels contributes to the industrial cycle of carbon

dioxide in the atmosphere. This contributes to the greenhouse effect which has

been a reason for global warming. Nitrogen is found in the atmosphere and makes

up about 78% of the earth’s air mixture. Oxygen makes up about 22% of the

earth’s air mixture and pollutants make up about 1% of the earth’s air mixture.

Nitrogen is important in the development of organisms on earth as the make

compounds such as proteins and amino acid. These compounds are important because

they make up DNA and other compounds crucial to the formation and sustenance of

life. Changes in an ecosystem are brought about by different factors. For

example ecological succession brings about the replacement of one community by

another in an ecosystem. In other instances organisms that colonize an area

with no community present are considered pioneer organisms. A climax community

is the final stage of development of organisms and can be disrupted by a major

catastrophe like a volcanic eruption.
