Plate tectonics

northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois. Southwestern Indiana and northwestern Mississippi are also close enough to receive significant shaking from large earthquakes. Despite being far away from current plate boundaries, the New Madrid Fault is a dangerous zone because of the active faults that are actually buried 100 to 200 feet deep in soft river deposited soils of alluvium, making these faults harder to study because of their location underground.…

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…

Participating contractors will use the following equipment and apply certain retrofitting procedures to ensure that the property is earthquake resistant: Anchor bolts Anchor bolts and sill plates improve the connection between the concrete foundation and the wood framing of a house. This procedure keeps the property from sliding. Braces Braces strengthen cripple walls with plywood to prevent the house from toppling off its foundation. The…

All volcanoes are amazing to see in action. Cinder Cone Volcanoes, Stratovolcanoes, and Shield Volcanoes are different types of volcanoes with their similarities and differences. All volcanoes are magnificent features of Earth’s crust. 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…

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, and uplift accompanied by both normal and thrust faulting. It was responsible for creating volcanic activity, mountains and…

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.…

2.1. Decomposition The deterioration is required on the grounds that there are two issues. First there can be some obvious clamor leftover in the smooth regions. Second there can be some apparition ancient rarities along edge limits with smooth background [1]. Such clamor lingering and apparition ancient rarities make the reproduced shading picture outwardly unpleased in a few regions. The clamor remaining in the smooth ranges is essentially brought about by the moderately low nearby flag to…

Mount St. Helens By Kyle Lockhead Volcanoes destroy and volcanoes create. The catastrophic eruption of Mount St. Helens on May 18, 1980 was devastating. It shows the destructive power of a volcano. Yet, over a time span longer than human memory. Volcanoes have played a key role in forming and modifying the planet we live on. More than 80 percent of the Earth's surface is from a volcano and the eruption from Mt St. Helens is big part in the environment but the mountain of Mt St. Helens will never…

May 22nd, 1960 in the afternoon at 7:11, people in Chile would lose their lives, because of a 9.5 magnitude earthquake. This catastrophe occurs when the Nazca plate released tension and descended 15 meters under the South American plate. Since the earthquake occurred in the middle of the Pacific Ocean it resulted with horrible tsunamis hitting the coast of Chile, Hawaii and Japan. This earthquake was enough to leave people homeless and dead. The destruction cost millions of dollars. Lastly, the…
