* All ecosystems function in a state of dynamic equilibrium or a continual state of balanced change. * This state of dynamic equilibrium is the product of the interrelationship of the elements in the ecosystem: the atmosphere‚ lithosphere‚ hydrosphere and biosphere. * Change occurs because the interrelationship between minerals‚ energy and communities varies over time. * It is also the interdependence of these four elements that makes an ecosystem vulnerable. * A change beyond the limits of

1. Which of the following describes what would happen when toxic waste is accidentally spilled into a groundwater system? A) Gasoline and kerosene would float on the water table‚ but most pesticides break down chemically when they reach the water table. B) Gasoline and kerosene would float on the water table; ethyl alcohol would dissolve and disperse in the groundwater. C) Sulfuric and nitric acids would sink to the bottom of the aquifer; kerosene would accumulate as a layer just below the water

The unity of man and nature. Human beings live in the realm of nature‚ they are constantly surrounded by it and interact with it. The most intimate part of nature in relation to man is the biosphere‚ the thin envelope embracing the earth‚ its soil cover‚ and everything else that is alive. Our environment‚ although outside us‚ has within us not only its image‚ as something both actually and imaginatively reflected‚ but also its material energy and information channels and processes. This presence

ENVIRONMENT AND ECONOMIC DEVELOPMENT Introduction 1. The world is entering another millennium. Amidst the situation of dramatic revolution in technology in almost every sphere of life‚ humankind is probably preparing it to face the new challenges of the coming millennium. Though many challenges are yet to be identified‚ their number is not at all encouraging and it is difficult to set priorities. 2. The most challenging is probably the population boom. Because‚ together with this problem

or solid (snow‚ sleet‚ etc.) precipitation. Water transport can also take place on or below the earth’s surface by flow. The hydrologic cycle is used to model the storage and movement of water between the biosphere‚ atmosphere‚ lithosphere and hydrosphere. Water is stored in the following reservoirs: atmosphere‚ oceans‚ lakes‚ rivers‚ glaciers‚ soils‚ snowfields‚ and groundwater. It moves from one reservoir to another by processes like: evaporation‚ condensation‚ precipitation‚ deposition‚ runoff

Case Study 1: Great Barrier Reef - 1. Introduction Coral reefs are on the most complex ecosystems on earth. They are predominantly found in the Indian Ocean and on the Western edges of the Pacific and Atlantic Oceans. The global distribution of coral reefs is influenced by a number of factors‚ including life and sea surface temperature. Coral reefs require such a unique set of biophysical interactions that they are highly vulnerable to human-induced change. For example‚ just a small change in sea

Environment not only includes the surface features and the flora and fauna on it‚ but also the zone of atmosphere and hydrosphere above and the mantle of the geological structure below. Hence‚ it has a volume or a zone in a cubical dimension. Environment has a regional and also a national aspect of analysis. The environmental engineering profession works to protect and manage
