In the United States there are many different types of rock formations. For example‚ there is the Tuscarora formation and the Navajo sandstone. These two formations have many differences and similarities. Like their location which differs. The Tuscarora lies in the eastern coast‚ while the Navajo lies in the western coast. From the formations being wide and beautiful they both form many attractions! To begin with‚ the Navajo sandstone was deposited in the mid Jurassic period ( Herbert‚ 2015)

Rubidium To start off this amazing element has just a little bit of history to it. At first when I heard about this element I thought it was some type of gas but it can turn it to a liquid at a certain type of liquid. But is actually a very shiny type of metal. Rubidium was discovered by Kirchoff and Bunsen in 1861 through the use of a spectroscope. Rubidium metal can be made by minimizing rubidium chloride with calcium with other substances. The cost of this metal in small quantities is approximately

Introduction Rose quartz is a pale pink to rose-red variety of quartz. Quartz is the second most plentiful mineral found in the Earth’s crust. Rose Quartz occurs only in massive formations‚ with no crystal faces‚ edges or points. It is often hazy or turbid; therefore it lacks good transparency. It also contains microscopic fibers‚ which can on occasion produce a cat’s eye or star effect within the stone. Rose quartz crystals are formed when the pressure within the earth pushes molten lava into

the following question: Relate the generation of all three rock types (igneous‚ sedimentary‚ and metamorphic) to plate tectonics. I will start first‚ with igneous rocks and how does it relate to plate tectonics. Second‚ with sedimentary rocks and progressively keep on answering how all three types of rocks relate to plate tectonics. Will be giving as much information I learned from class. To assure‚ answer is fully answered. The igneous process begins when magma forms by melting at depth‚ followed

Introduction Franklinian basin is one of the oldest basins in North America. It is a passive margin basin in arctic Canada that extends from northeast Canada to North Greenland (Ineson‚ 1988). The origin of Franklinian basin has not been extensively studied‚ but some authors (Miall & Blakey‚ 2008; Henriksen & Higgins‚ 1998) suggested a late Precambrian origin which began with the rifting of Rodinia (a supercontinent) about 700 Ma. Since the rifting of the Rodinia‚ Franklinian basin has undergone

Q1(a). What are the important characteristics of clays? Clay is an inorganic materials mineral which contain on fine particle‚ normally grain size is near about <1/256mm. It shows good plasticity in wet form but become brittle when it is dried. It is good insulter of electricity and thermal conductivity. Porosity is also another important characteristic of clay.[1‚ 2] (b)What is the structure of clays? Mostly‚ clays have layers structure. They form combination of tetrahedral silicates and octahedral

Ancient geography The Cassiterides‚ meaning Tin Islands (from the Greek word for tin: Κασσίτερος/Kassiteros)‚ are an ancient geographical name of islands that were regarded as situated somewhere near the west coasts of Europe. The traditional assumption‚ ignoring Strabo‚ is that Cassiterides refer to Great Britain‚ based on the significant tin deposits in Cornwall. Herodotus (430 BC) had only dimly heard of the Cassiterides‚ "from which we are said to have our tin‚" but did not discount the islands
