Introduction With increasing industrialization, energy consumption and demand have steadily grown at a rate of 2.2% per year from 2005 to 2014, and continue to rise. [1] Meanwhile, the production of hydrocarbons from conventional resources is declining. In order to meet the rise in energy demand, new hydrocarbon reserves must be found and produced. Salt is an ideal hydrocarbon trap because of it’s low permeability and capacity to deform under stress and temperature. Therefore, large oil and gas reservoirs

What is a biogeochemical cycle? -A biogeochemical cycle is a process in which a chemical substance moves through stages and eventually makes its way back to the beginning. Why are they important? They allow resources to be recycled such as water which is very important. Water Cycle (H2O) Steps of the Water Cycle Step 1 Evaporation: Process where heat energy turns water into water vapor. Step 2 Condensation: Because of the low temperatures in the atmosphere, as water rises it causes the water vapor

The Damming of the Yangtze River Since the 1920's, when the dam was first proposed, the Three Gorges Dam has been a topic for debate in the People's Republic of China. The construction of the world's largest hydro-electric project on the Yangtze River would be a detriment to the native flora and fauna, submerge rich farmlands, destroy archaeological sites, and force the evacuation of millions of people. Faced with international, as well as domestic, criticism about the ecological and social havoc

Yosemite’s geologic historic was about 500 million years ago. Back then, North America lay near the equator and California was covered by a tropical sea. Rivers from North America flowed into the ocean, flushing great amounts of sediment off land. As the layers of sediment grew

oxygen content of the water increased. After 1800 mya, Banded iron formations are rare, but terrestrial red beds are common for the first time suggesting that iron is being oxidised and precipitated in soils and rocks on land in the source area of sediments instead of being dissolved and carried into the oceans in its unoxidised form. Thus, it has been reasoned that the BIF-red bed transition marks the rise of atmospheric oxygen. Complimentary information comes from detrital uraninite in Archean and

All of us need water; our body is made approximately of 60% of water. This liquid is so important for us that over the years the way in which it is delivered to the consumer had developed to increase the quality of the final product. In order to give to the consumer high quality drinking water, the distribution systems had to be developed to insure that the same water in which goes out of the water treatment plant is the water in which goes out of the consumer’s sink. Over the years some methods

measurements. Some of this data includes ice cores, tree rings, coral reefs, and ocean sediments. For example, corals build their bodies with calcium carbonate that contains trace metals and isotopes of oxygen that can be used to determine the temperature of the water the corals grew in. Therefore, Past Ocean Acidification is often inferred from a decrease in the accumulation & preservation of Calcium Carbonate in marine sediments, possibly indicated by an increased degree of fragmentations of foraminiferal

is stored in the form of biomass. Wetlands also function as natural filters. As water further upstream is transported out to sea, it is filtered and cleaned of pollutants and chemicals as it travels through the wetland. This is due to the varying sediments and fix vegetation. The clean water it provides keeps estuarine habitats functioning

Connecticut got its shape in three major ways. Those are ways are glaciation, plate tectonics, and weathering and erosion. One major way Connecticut got its shape was from glaciation. For example, glaciation formed Jobs Pond. Jobs Pond is a giant kettle hole, which is a depression caused by the impact of a massive chunk of ice, or a glacier. According to The Mystery Of Jobs Pond, geologists and hydrologists the water level rises and falls with the groundwater level in the area, because porous sand

Sea-level rise is one of the most significant effects of climate change. As global temperatures rise, ice in the polar-regions will continue to melt, dumping tons of additional water into the ocean. Warmer water temperatures will also lead the oceans to expand high projected rates of future sea-level rise. “These factors will cause sea levels to increase and swamp coastal areas all over the world” (Oceans and Sea Level Rise). Particularly, countries which are located in low-lying areas as well as
