some of which can cause problems for humans‚ plants‚ and animals. There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles into the air

Dasean Matheson 11/25/13 APES Ms. Sarameinto Population is the largest increasing factor in our world. This factor is the cause of many events in our world. Poverty hunger and war are just some of the immediate effects of increasing population. Among these extreme causes the less immediate events will be seen with air pollution‚ land degradation‚ which is the effect that’ll have the longest term effect on the world. But how can these events are avoided? Is there any hope of stopping this

Atmosphere Evolution on Rocky Planets Atmosphere can be defined as a gaseous compound layer surrounding a large body mass suspended by means of gravity and centrifugal force caused by rotation [1]. Atmospheres of planets have not always been the same‚ its evolution comprised of complex development across million years of geologic time affected by various changes of variables inside and outside its planet [2]. Of the interest of this essay is the atmospheric evolution of a rocky planet. Rocky planet

Ozone Depletion Ozone Layer is formed when ultraviolet radiation (UV) splits a molecule of oxygen (O₂)‚ and the free oxygen atoms (O) combine with other oxygen molecules. Ozone acts as a filter in the upper atmosphere‚ preventing the harmful ultraviolet radiation of the sun from reaching the earth. Carbon compounds such as carbon dioxide (CO₂) and chlorofluorocarbons (CFCs)‚ nitrogen oxides (NO)‚ and methane break up Ozone molecules. Acid Rain Sulfur and

Events which may have gone unnoticed previously‚ only become hazards when there is intervention with humans and their lifestyle.

Do we really want to take that opportunity away from our descendants? With the ozone layer depleting more and more each day they are going to need all the protection they need from the sun’s harmful rays. Possibly a cure for cancer‚ and people are treating these living organisms like they are nothing. Maybe if there was more education

The loss of polar ice over the coming decades will lead to irreversible climate change and alter the face of the planet. The earth as we know it is a unique planet composed of global masses of air‚ land and sea. Each body interacts with each other in unique physical and biochemical ways and minute changes in one mass can lead to irreversible changes to another. Climatology is that scientific endeavour that monitors climate systems to explain loss of polar ice. The variables impacting climate and

Without proper planning and development‚a land stripped of its vegetation cam rapidly succumb to soil erosion. * The absense of plant root systems makes the soil structure unstable. * When it rains heavily for a long period of time‚ the top layer of soil disintegrates easily and this leads to landslides esspecially on steep hillsides. * The eroded soil is then carried away by moving water and deposited at the bottom of rivers‚which
