Amphibolite is a foliated metamorphic rock. The orientation of the foliation is 251/75. It has a gneiss foliation and stripes of minerals segregation. Minerals such as white Quartz, shinny Plagioclase, green Amphibole, and pistachio green (yellowish) epidote were seen on the fresh surface. Greenschist is coarse grained metamorphic rock that contains minerals such as yellow epidote, flakes of mica and green serpentine and chlorite. Metasediments with various colors were seen such as Quartzite…

How do scientists known what the center of the earth is? There 4 ways how scientist found out about the center of the earth ( aka inner core and outer core). Answer 1: Geologists hypothesize that the Earth's center is composed of predominantly iron. The outer portion of the center, known as the "outer core", is thought to be liquid iron. While the interior portion of the center, known as the "inner core" is thought to be solid iron. Answer 2: The main evidence for the structure of the Earth…

One type of volcano is a cinder cone. “A cinder cone volcano doesn’t have any horizontal layers of solid lava flows mixed with layers of other rock,”stated on zmescience.com. Cinder cone volcanoes are sloped like a mountain, although they have a large number of very liquid lava flows. When people think of a volcano most of most of the time they think of a cinder cone volcano because of it’s tall and sloped cone shaped. “One kind of volcano is a cinder cone volcano, a volcano mainly made up of…

Southern Europe includes countries of the Iberian peninsula (Spain and Portugal), the Italian peninsula, southern France, and Greece. Also, includes the Balkan countries of Southeast Europe. It is a mountainous area and a Mediterranean Vegetation region that has mild climate. Alpine Orogeny is a phase formed fifty million years ago when the Eurasian continent plate and African continent plate collide together. The Alpine Orogeny produced intense metamorphism of rocks, crumpling of rock strata,…

There are many intriguing things about how the earth was made. One of the marvels of the earth is its gold deposits. Gold appeared to be both uncommon and normal on the off chance that one is to genuinely take a gander at it. In spite of the fact that there is a decent lot of gold on the planet, it is progressively elusive, therefore why it is somewhat uncommon. In California, the gold was pushed through the stones and encased into quartz. These are called quartz veins, they framed in many…

all land. Pangea went under a process called continental drift, founder by Alfred Wegener, which is caused by geo-process. Geo-process results in changes to the earth's surface because of tectonic plates causing mountain building, earthquakes, and volcanos. First off, convergent plates cause many different types of mountains, like the folded mountains. Their called a folded mountain because of the folding plates. The denser plate goes underneath, which will eventually turn into molten, while…

Earthquakes and volcanoes go hand in hand like peanut butter and jelly or rice and beans. Where there are volcanos there are usually tectonic plates beneath them either pushing against or pulling away from one another. Take for instance the Cascade Mountain Range in Northern California and stretches through Oregon and into Vancouver, British Columbia and sits northeast of the San Andreas Fault line that runs 750 miles through California. This fault creates the tectonic boundary between the…

1820 and 1854, but many eyewitnesses reported eruptive activity in 1858, 1870, 1879, 1882 and 1894 as well as there was no obvious evidence but as of 2010 mount rainier is listed as a active volcano. and it is listed as a decade volcano. 150,000 people live on top of old lahar deposits of Rainier. the volcano with it…

A small western town, Libby Montana is known as the land of shiny mountains, originating from loggers and fur traders. Amongst the mountains is a 25-26 million year old volcano that was discovered to be a source of ore. Strip mines soon developed around 1923, providing well paying jobs for the citizens of the sleepy town. Zonolite merged with W.R. Grace and Company, becoming the the biggest employer of the towns men who pride themselves on being hard working and family oriented. These men worked…

How many volcanoes are going off right now? What are the volcanoes doing to the people; what are they doing to the earth? So, how do volcanoes shape the earth? Volcanoes can be very harming but, they can also be helpful. For instance they help the soil become richer overtime. They can also be harmful because, they can wipe out towns and cities. They can also be harmful because, they put so, much smoke into the air during the eruption. So, as you can see volcanoes are more than just hot lava.…
