sciences in a comprehensive and interrelated study of the oceans in all their aspects and relationships. Oceanography integrates chemistry, physics, geology, and biology. Astronomy: the study of the universe (is useful in determining the origins of our own environment) Hydrosphere: is a dynamic mass of water that is continually moving, evaporating from the oceans to the atmosphere, precipitating to the land, and flowing back to the ocean. Atmosphere: The gaseous portion of a planet; the

Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have

rocks, from the surface to depths greater than 5 km. Water is also tied up in living organisms; humans, for example, contain about 70% water. Water is stored in ice sheets large and small, it occurs in various surface water bodies, and, of course the oceans, the reservoir of the great majority of Earth's water. The hydrosphere, then, is intimately tied up with all of the other spheres that make up our whole Earth system. Inventory of Water Here is a partial breakdown of

Fiji Island is a “pearl” embedded in the South Pacific Ocean. With thick tropical trees shading the cool sands, white beaches glistening in the sun, and colored ocean water accompanying grotesque coral reefs and fish, you will be amazed by the vitality and brightness of Fiji, an island full of imagination. With an official language of English, Fiji welcomes tourists all around the world. Housing Fiji is a suitable place for water sports due to its island location: golf, scuba-diving, cross-country

dumping into the ocean, but this article also shows how people are saving our coasts from further pollution by getting out there and actually doing something that is good for our environment. This article is very interesting because of the fact that it brings in the perspective of ordinary people and what they do to help as well as the perspective of scientists and what they do to help. This is a very important subject to learn more about because if we do not stop dumping into the ocean than we will

It is also useful in solving recurring problems which prove difficult to solve. Basically it is composed of various parts which are related either directly or indirectly. They all entail processes which produce outputs from inputs. It is not only dynamic but also holistic and seeks to produce results of the complex problems. Systems thinking is the only critical way to solve complex issues impeding sustainability challenges and develop quality solutions. Since its conception in 1920 by Jan Smuts

It could get a lot warmer. (GLOBAL WARMING) Full Text: COPYRIGHT 2005 Business Communications Company, Inc. If humans continue to use fossil fuels in a business as usual manner for the next few centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar to 14.5 degrees warmer than current day. These are the stunning results of climate and carbon cycle model simulations conducted by scientists at Lawrence Livermore National

Earth is a blue planet as about 71% of its surface is covered by water. But, not all water is usable for human life. According to one study, Oceans, sea and bays comprise 96.54% of total ground water. 1.74% is locked up in glaciers, icecaps and permanent snows. Only 1.69% of total water is ground water which includes both saline and fresh water. Fresh water hardly comprises 0.76% of total water resources of the world. Ground water is essential for sustenance of human life. Ground water is

of serpentinite and other metabasic bodies occurring within the zone (Tjia & Syed, 1996). During Early Permian, the rifted Sibumasu oceanic and East Malaya-Indochina continent from Gondwanaland collided. Sibumasu was subsided at the Palaeo-Tethys Ocean. This subduction continued till Middle to Late Permian until the whole oceanic crust was melted into the mantle. The collision was then continued by continent-continent collision during Middle to Late Triassic, resulting Main Range development in Peninsula
