+    Earth Science impacts every aspect of modern life. Hence, the concepts of Earth Science 
+are fundamental not only to the field of Geology, but also to Environmental Science, natural 
+resource management, civil engineering and society at large. Earth Systems provides an 
+introduction to Earth Science, including earth materials, geologic history, geological and 
+physical geography process at the Earth's surface, and the complex interplay between the 
+lithosphere and landscapes. Additionally, the unit provides readily accessible examples of 
+the use of scientific reasoning for understanding complex natural systems. Hence, Earth 
+Systems is a foundation unit for further studies in Geology and Environmental Science, but 
+more importantly, serves as a broad introduction to the very world we live on and to the ways 
+of science in general. Such a background is highly desirable for any informed citizenry for 
+understanding complex issues of resource, environment, and societal development.

+        <p>
+	Bowen's Reaction Series arranges the silicate minerals in the order that they crystallise from a magma. The minerals at the top of the series crystallise from the melt at higher temperature than those 
+	lower down. It contains a continuous series, (right hand limb), discontinuous series (left hand limb), and the residual phases that describe the reaction pathway of different silicate minerals. 
+	The discontinuous series crystallises different minerals, with abrupt changes separating the different minerals due to a mineral reacting with the melt to form a different mineral (eg. Olivine reacting to crystallise pyroxene). 
+	The continuous series always crystallises plagioclase,  but the composition of the plagioclase varies from more calcic at higher temperatures and more sodic as the temperature decreases. 
+	with the minerals at the bottom of the series being more stable, and less susceptible to weathering. 
+	The residual phases are the minerals at the bottom and crystallise last. Bowen's reaction series also predicts the stability of minerals in the low pressure conditions at the Earth's surface, 
+	<br /><br />
+	It should be noted that all reactions do not start crystallising olivine/anorthite-rich plagioclase and continue through until they crystallise quartz. 
+	The actual reactions depend on many factors, such as the chemical composition of the melt, temperature, pressure, and amount of fractional crystallisation. 
+	For example, basalts form from the crystallisation of olivine, pyroxene and calcic plagioclase meaning that crystallisation stopped without the series progressing. 
+	If more fractional crystallisation were to occur, more intermediate and felsic minerals can crystallise.

+        The heat contained within the Earth is generated by two main sources: the formation of the Earth,
+        and the decay of radioactive isotopes. The Earth was formed by the accretion of a large number of
+        planitesimals as it cleared its orbit. The impact of those planitesimals generated a large amount
+        of heat which is still being lost from the Earth’s core today. The other source of heat comes
+        from the radioactive decay of elements within the crust and mantle of the Earth.
+        The primary radioactive isotopes in the Earth are uranium-235, uranium-238, thorium-232,
+        and potassium-40. Radioactive decay is the dominant form of heat flow at the surface of the Earth,
+        providing approximately 80% of the heat budget.
+        <br /><br />
+        The temperature of the Earth changes from around 0°C at the surface to over 5000°C in the core.
+        The geothermal gradient in the crust is approximately 30°C per kilometre in the crust on average,
+        however there is significant local variation due to things such as the conductive abilities of the
+        rocks at particular locations, as well as the presence of nearby magmatic intrusions.
+        The geothermal gradient in the mantle reduces significantly, down to approximately 0.3°C/km.
+        The base of the lithosphere is defined by the 1000°C isotherm. The base of the mantle is at
+        approximately 2800°C.
+        <br /><br />
+        The method of heat transfer changes throughout the Earth. There are three main mechanisms for
+        heat transfer in the Earth: conduction, convection, and radiation. Starting in the inner core,
+        the main method of heat transfer is by conduction through the solid material. In the liquid,
+        outer core heat transfer is by both conduction and convection. The mantle is dominated by convection,
+        which is the driver of plate tectonics. The crust is again dominated by conduction, and finally
+        energy escapes the Earth to the atmosphere by radiation.
+        <br /><br />
+        Pressure in the Earth continually increases with depth, according to the formula P = gρz,
+        where g is the gravitation field strength, ρ is the density and z is the depth. The main
+        difference in the pressure gradient is cause by the different lithologies in the layers
+        of the Earth. The average density of continental crust is approximately 2.7g/cm3 and
+        is ~3.0 g/cm3 in oceanic crust, and increases to about 3.3 g/cm3 in the mantle.
+        The increase of pressure with depth in the Earth affects the dominant mineralogy, as
+        well as the increase of the melting point of different minerals.
+        <br /><br />
+        The structure of minerals, such as olivine becomes unstable as pressure increases.
+        Below about 410km olivine becomes unstable and transforms into wadsleyite, which has the
+        same chemical composition as olivine, but has a different crystal structure. As depth
+        increases, wadsleyite transforms to ringwoodite, which subsequently transforms into
+        perovskite at about 600km.
+        <br /><br />
+        At higher pressure, minerals have a higher melting point. The effect is this phenomenon
+        is that the dominant method of melting in the mantle is not by increasing the temperature
+        past its melting point, but by decompression. Due to convective processes in the mantle,
+        as parts of the mantle rise the decrease in pressure lowers the melting temperature and
+        can cause the mantle to melt.

+        <p>
+	The Earth's structure is differentiated in three distinct layers: the core, mantle, and crust. The layers are distinguished by a change in the velocity of seismic waves at their boundaries. 
+	The crust is the upper most part of the earth, with depths ranging from an average of 7km in in the oceans, to an average of 38km in continental crust. 
+	The crust thickens underneath mountain ranges, and can reach depths of 90km underneath the Himalayas. The composition of the crust also differs between oceanic and 
+	continental environments. Ocean crust is young mafic crust dominated by basalts and gabbros that is recycled regularly(~300Ma) due to subduction processes. 
+	Continental crust is much more varied in structure and composition than oceanic, but has an overall average composition of granodiorite. 
+	<br /><br />
+	The boundary of the crust and mantle is defined by the Mohorovi?i? discontinuity, commonly referred to as the Moho. 
+	It is defined by a sharp increase in seismic wave velocity, due to a change in material properties between crustal rocks and mantle rocks. The mantle is dominated by 
+	silicate minerals that are rich in iron and magnesium, chiefly pyroxenes and polymorphs of olivine, forming peridotite. The mantle, while solid, behaves plastically, 
+	allowing to flow at very slow rates.
+	<br /><br />
+	The core is distinguished by the absence of S waves, leading to the inference that the core is liquid. The core is separated into the outer core and the inner core. 
+	The outer core is liquid dominated by iron and nickel. The inner core is solid, as determined by the strong refraction of P waves at the inner core-outer core boundary, 
+	and was formed by crystalizing minerals from the liquid part of the core as the Earth cools. 
+	<br /><br />
+	The crust and mantle are also further distinguished by material properties into the lithosphere, asthenosphere, and mesosphere. The chemical composition is 
+	uniform throughout the mantle though, but changes in pressure and temperature determine which polymorphs will exist at different depths. 
+	The lithosphere contains the crust, and the upper part of the mantle down to ~100km under oceanic crust, and 200-300km under continental crust (Twiss & Moores, 2007). 
+	The lithosphere-asthenosphere boundary is defined by the 1300K isotherm, which is the temperature where olivine starts to behave viscously.  
+	The rocks in the mesosphere are under more pressure than those in the asthenosphere, so no longer behave viscously.</p>
