Download file to see previous pages Crude oil is a product of pressure, organic matter from ancient living creatures and certain formation of the rocks in the strata. The porous and permeable rock reservoirs are the collection point of the hydrocarbon fuels. This is possible due the accumulation of these liquid oil and gases such as methane and shale gas. There are however some important factors that ensure the conditions are right for the formation of the crude oil. These factors include the existence of what are referred to as source rocks, reservoir rocks, traps and oil and gas seals. Each of the named features should definitely be present in order for the conditions to be optimal and to allow the proper formation of crude oil.
Oil and naturally occurring gas come from certain types of rocks. These rocks are sedimentary in type and were deposited in water during the changing phases of the transformation of the Earth. These rocks are known as source rocks. Mineral fragments, remains of organic substrates, and moisture. When this type of rocks experience a lot of pressure and heat from the compressing by other layers of rock. The term sedimentary comes from the characteristic of the rock to be formed from sediments, these include organic matter. The sedimentary rocks were usually deposited as soil or mud at the bottom of lakes and oceans. This excessive pressure forces the organic matter from the sedimentary rocks to start to be heated and when the right temperatures reach oil and gases are expelled from these rocks. ...Download file to see next pagesRead More

After miners have extracted the ores from the ground, they then refine them using other substances to remain with the valuable elements. Extraction and processing of these iron ores is an expensive venture but it largely depends on mineral concentration and the form it occurs in the ground. In order to establish if a mine is commercially viable, the engineers evaluate if it has substantial mineral and metal deposits whose proceeds will generate income over and above the mining costs. In mineral extraction, there are terms that help us understand this whole refining process. Industrial minerals are stones and other naturally occurring substances that are mined and processed because they have an economic value. This is because they...

...Overview There has been growing fear between many scientists that human interferences are modifying the capa of ecosystems to endow with their goods (e.g. freshwater, food, pharmaceutical products, etc) and services (e.g. purification of air, water, soil, sequestration of pollutants, etc). This can lead to ecosystem disorder and bear a significant impact on humans and animals as well as plants, in a variety of ways and through complex pathways. These are moreover modified by the population's existing vulnerability and their future capacity to execute adjustment measures. Because of these concerns, the prominent changes, at least many of it, occur so in the arctic region. The basis for this is strong positive feedback associated... There has ...

... Geology Earth itself has had its share of unfathomable mysteries and the universe with all the heavenly bodies occupying it appears vast in mystery and beauty. For one, the exhibition via the Cullman Hall of the Universe is particularly striking. Viewers like me are chiefly left with an impression that universe indeed is ever-expanding. At that moment, I was brought to ponder about the size of God who is behind such an incredible idea which reflects the great astrophysical value of matters in the outer space. During this stage, the sight of the exhibits drew me to the interest of imagining how quantum particles could have possibly been of the evolution process of the cosmic materials comprising the universe. Similarly, the Heilbrunn...

...The history and arguments about the origin of the earth and evolution have given many scientists sleepless nights trying to unearth what might have actually happened long before we came into being. Scientist hope that one day the matter will be put to rest by providing evidence and be able to prove to the world beyond any reasonable doubt that certain specific activities took place. Their progress is mainly centered on the rocks which are the source of their evidence. The discovery of rocks which will provide the evidence and chronological evidence was a great milestone. Religious divide on the other hand seem to disagree with idea of millions of years and squeeze it to before six days of creation (Dawkins. 2012). Having gone... history and...

... of the Saddle Mountain Geology A close analysis of the rock presented highlights that it is Miocene basalt. Geological research has indicated that the Saddle Mountains formed in the Miocene and a post Miocene age when the uplifting of the Miocene volcanic rocks took place. The uplifting took place in a manner that saw the folding of the volcanic rocks in a relative design to the synclinal valleys. Many geologists have highlighted that the quaternary normal faults are the description for the faulting that resulted. This led to the formation of class B structures that characterize the Saddle Mountains. It is in these mountains that the described rock was found (‘Washington Geologic Newsletter’ 56) According to further research...

... Geology assignment Imagine you pour water on the sedimentary rock sand sandstone. What happen to the water over time? The water will flows into the pore spaces between the sand grains 2. Approximately how big are pore spaces in sediments or rock? About the size of a rice 3. Two student are discussing the best analogy for most ground water Student I: I think most ground water is like water in large underground holes or caves. When we look at water on Earth’s surfaces, it gathers in big pools, so I think it would be the same underground. Besides, there is not enough room in rocks for water to fit. Student II: I think most groundwater is like water in sponges. Water fills in lots of very small empty spaces within certain types of rocks, like...
