The Standing Rock Sioux Tribe and the environmentalist and local citizens raised high concerns about the potential health and environmental consequences of oil spills‚ because after many research’s pipelines always leak. The pipeline can contaminate the Missouri River‚ which supplies drinking water for millions of Americans households and irrigation supply for thousands of acres farming lands. The Native American tribe is concerned about the vicinity of the pipeline to their reservation. They are

band in a Gneiss. An anticline occurs on a much larger scale. The both are affected by the same compressional stress. In an anticline the oldest rocks are exposed in the middle of the structure and get younger as you move out. They are likely to out crop especially if the syncline has a resistant layer. On a map you would look for an area with older rocks in the middle with younger units as you move outward. The difference between a synform and a syncline are the same as with the antiform and the

Photographs During the Civil Rights Movement The Little Rock Nine were a big part of starting the Civil Rights movement. The Little Rock Nine was made of 9 children‚ all of which black‚ who volunteered to make the first attempt of integrating white schools in America. Integrating white schools was on the top of every black students bucket list at the time; white schools got all new materials while the black aschools got hand-me-downs from the white schools. Photography played a big role in spreading

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

Porphyritic granite Porphyritic granite is an igneous rock‚ which consists of orthoclase feldspar‚ quartz and orthoclase. This type of rock is made up of two different grain sizes‚ larger crystals referred to as phenocrysts‚ and smaller granite sized grains. The name for porophyritic originated from the Latin word porphyry which is defined as purple‚ and is known as a color royalty. This rock has been used as early as 18 AD and was discovered by a Roman legionnaire named Cauius Cominius.

living creatures‚ but many do not realize how toxic it can be to non-living objects. “Acid rain leads to deterioration of rocks such as limestone and marble (globalwarmingandu.com)”. Acid rain will corrode the rock surface which dissolves the material and then they will be carried away. We tested acid on different types of rocks. The hypothesis is that the sedimentary rock will have the largest change in mass. After a certain degree‚ acid rain is capable of damaging the entire environment. It

The Origin of the Earth‚ One of God’s Hidden Secrets “Much of geology is pure speculation and is as such on the same basis as philosophy‚ or must be accepted on faith‚ as the truths of theology” (Rehwinkel 177). For geologists this means that any theory of how the Earth‚ atmosphere and life originated‚ takes faith to believe‚ whether it is the evolutionist’s view or the creationist’s view. Creationists believe that the Earth was created 6000-7000 years ago. This number is based on what the Bible

On the Digermulen Peninsula‚ the succession starts with the classic Neoproterozoic glacial tillite of the Mortensnes Formation (Fig. 3). This tillite has traditionally been tentatively correlated by many workers (e.g.‚ Rice et al. 2011‚ and references therein) with the type ’Gaskiers’ glaciogenic succession in Newfoundland‚ which is between 584 and 582 Ma old‚ based on zircon U–Pb ages from intercalated ash beds (Bowring et al. 2002). The Mortensnes Formation is separated downwards from the ’Marinoan’
