Essays on Geochemical

There are literally a lot of elements that hold at least a certain level of relevance in the geochemical and bio-geochemical industry or cycling. One important thing to know about these elements is that most, if not all, of them are non-renewable. Most are stored in ores found underneath the earth’s surface. What makes the process of obtaining those elements more problematic is the fact that they need to be mined, extracted, and processed before they can be deemed usable for industrial and consumerism-related purposes. These ores are abundant and this is why at this point, they are practically inexhaustible. ...

Certain elements involved in the geochemical and biogeochemical cycling are of great concern due to their limited availability both naturally or through industrial manufacture of the compounds involved in the cycles. Some of the processes involved are chemical reactions with other elements or substances. Some of these reactions are irreversible chemical reactions. This implies once the reaction has taken place, the elements are removed from natural cycle and they cannot be replaced again. As such, the more the cases of irreversible reactions, the greater the rate of reduction of these elements from the environment. Ultimately, there could be less ...

Waldron and White declared that the manganese rich sedimentary rocks of Nova Scotia and Wales are Cambrian. They discovered that these rocks were deposited in a deepwater turbidite basin called Megumia and not on the Avalonian shelf. We found that the geo-chronological data does not conflict with the Early Ordovician deposition age for manganese rich sedimentary rock of the Rheic suture. This region included Nova Scotia and northern Wales. They said that “Megumia” is part of the Avalonian plate and manganese rich rocks formed on its shelf. They performed a coticule study and found that occurrences of coticules and Mn-rich ...

Question One

Naturalistic science explanation of the origin of the universe, the origin of life and biological diversity and the time frames involved. Naturalists believe that the planet earth has existed for about six billion years (Smith 2000). The earth together with all other planets came to existence when a cloud of gases containing particles of dust, rock, ice among other particles collapsed to form solid concentrated mass.This resulted in rising temperature leading to formation of the sun. Most of the collapsing matter in the collapsing mass fell into the sun and the rest formed discs in an orbit around the ...

Water and Its Unique Properties

Water is has a unique physical and chemical properties which are essential to life and to the earth processes such as climate change. Water molecules generally consist of one oxygen atoms and two hydrogen atoms. However the atoms do not share equal electrons thereby making water slightly charged—exhibits polarity. Water molecules interact with other water molecule through a weak hydrogen bond. Hydrogen bonds allow water to interact also with other polar substances. Water is known as the universal solvent. Thus, it has the capacity to dissolve various polar substances like ammonia and nonpolar substances such as methane (Freudenrich, 2011). ...
