This field of psychology is dedicated to the study of reciprocal relationships between psychological processes and physical environments, both natural and man.

The changing vegetation occurs because when trees cannot get adequate water they start to deteriorate, leading to a decreased food supply for the wildlife in an area.

The remaining gases are often referred to as trace gases, [13] among which are the greenhouse gases such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Filtered air includes trace amounts of many other chemical compounds. Air also contains a variable amount of water vapor and suspensions of water droplets and ice crystals seen as clouds.

Many natural substances may be present in tiny amounts in an unfiltered air sample, including dustpollen and sporessea sprayvolcanic ashand meteoroids. Various industrial pollutants also may be present, such as chlorine elementary or in compoundsfluorine compounds, elemental mercuryand sulphur compounds such as sulphur dioxide [SO2]. The ozone layer of the Earth's atmosphere plays an important role in depleting the amount of ultraviolet UV radiation that reaches the surface.

The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes. Layers of the Atmosphere[ edit ] Principal layers[ edit ] Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude.

From highest to lowest, these layers are: The outermost layer of Earth's atmosphere extends from the exobase upward, mainly composed of hydrogen and helium. The top of the thermosphere is the bottom of the exosphere, called the exobase. It is the layer where most meteors burn up upon entering the atmosphere. The troposphere is mostly heated by transfer of energy from the surface, so on average the lowest part of the troposphere is warmest and temperature decreases with altitude.

The tropopause is the boundary between the troposphere and stratosphere. Other layers Within the five principal layers determined by temperature are several layers determined by other properties. The ozone layer is contained within the stratosphere. It forms the inner edge of the magnetosphere.

The homosphere and heterosphere: The homosphere includes the troposphere, stratosphere, and mesosphere. The upper part of the heterosphere is composed almost completely of hydrogen, the lightest element.

The planetary boundary layer is the part of the troposphere that is nearest the Earth's surface and is directly affected by it, mainly through turbulent diffusion. Effects of global warming[ edit ] The Retreat of glaciers since of Aletsch Glacier in the Swiss Alps situation inanddue to global warming. Effects of global warming The potential dangers of global warming are being increasingly studied by a wide global consortium of scientists.

The interaction between environment and society depends largely on the social and political system. Even the capitalistic and socialistic systems perceptions and reactions to the environment are quite different. The differential interactions are due to uneven distribution of natural resources, uneven economic and social development, dissimilarity of demographic factors, varying view points of the governments and individuals towards environment etc.

Continuous and exceedingly increasing rate of rapacious exploitation of natural resources, industrialisation, technological growth, unplanned urbanisation and profit oriented capitalism by the developed western world are responsible for grave environmental crisis and ecological imbalance not confined to their own countries but to the whole world.

The socialistic system of government gives more emphasis on the social importance of natural resources and environmental problems and the urgent need to tackle, these problems.

The emphasis on rational exploitation of natural resources and ecological balance was in the constitution of USSR. The changes in the relationship between man and environment depend upon the change in organisation and attitude of society. To improve environmental standard and to maintain ecological balance, the followings are some issues before the present civilized society.

Puts tremendous pressure on the natural resources and environmental quality. This is due to the fact that population growth leads to poverty which directly or indirectly declines the environmental standard.

Rational use of non polluted water resources: The restoration of water quality of our water bodies and their optimum uses are the challenges before the present society. To sustain and increase agricultural growth: The over cultivation of soil, results in nutrient deficiency, lack of organic matter, soil salinity and damage to physical structure of the soil.

To check soil erosion: The soil erosion can be prevented by the restoration of land or soil resources which are directly or indirectly related to strategies for the management of land, water and forest.
