1. Unit 1.0: Introduction to Geology Geology is the study of earth surface. Geology deals with the outdoors, which attracts most people. Geology deals with learning about the planets and satellites in the Solar System. 2. Unit 2.1: Mineralogy Mineralogy is a subject of geology. Mineralogy deals with the different properties of minerals. Mineralogy deals also with chemistry such as the structure of an atom. 3. Unit 2.2: Igneous Petrology Igneous petrology is basically one of the fields that deals

activity (Zobin, 2012). Therefore, correlations between volcanic gas studies and geophysical methods, such as infrasound and seismicity, provide understanding in volcanic phenomena and may predict volcanic eruptions (Kazahaya et al., 2015). Volcanic seismology is the study of the origin of seismic signals related with volcanic processes (Zobin, 2012). The nature of this science rests over the mathematical and physical approach that describes the sources producing seismic waves (Zobin, 2012). Volcanic

Before answers: What Causes Earthquakes? Earthquakes are caused when two tectonic plates collide with one another Why Are Some Quakes Stronger Than Others? Because, I guess the strength of the tectonic plates. My 5th Grade Presentation! (It has almost none of the info in the textbook.) (Plus, Mason Suida owns it, not me) (R.I.P Interlochen) I luv this. Tectonic plates rubbing against each other at the fault line! Fault lines are ends of rocks/plates. Things that are altered by plates Roads

earthquakes are more of a thermal process due to large amounts of heat generation, rather than large seismic activity. (Scholz 2002) Also, some earthquakes are not the result of faulting however, but caused by large landslides. In the early days of seismology, these differences were noticed qualitatively but the technology available during that time made it hard to accurately tell the difference. Before an earthquake takes place, there is a large buildup of potential energy. The energies involved in

followed on Sunday, November 1, 1755, by a cataclysmic shock and tsunami that killed an estimated 70,000 people, leveling the city of Lisbon, Portugal, while many of its residents were in church. This event marks the beginning of the modern era of seismology, prompting numerous studies into the effects, locations, and timing of earthquakes. Prior to the Lisbon earthquake, scholars had looked almost exclusively to Aristotle, Pliny, and other ancient classical sources for explanations of earthquakes.

Victoria Bruce brought together two accounts of Volcanic tragedy into one terrifying and exciting tell all, focused on the eruptions of Nevado Del Ruiz and Galeras in Northern and Southern Columbia. Bruce has first hand accounts from survivors of both eruptions and imagery that places you in the mud slides and the avalanches of boulders. Although there was a major difference in the casualties in both situations, both were equally devastating to the families of the deceased and the scientific community

the same time debated subjects science deals with particularly because there have been numerous attempts to try to explain the creation of the earth, its morphology, and current evolution. The tectonic plates and their movement are the basis of seismology which tries to explain the way in which the mountains and the seas we currently have on the surface of the Earth formed in the geological eras. The Ural Mountains are an example of how tectonic plates determined the formation of the landscape.

of subduction zones with some specifically focusing on seismology, the mantle wedge, phase changes, the fate of slabs and water in mantle. However, in this review, I attempt to provide a broad summary that emerges from recent observations and model of subduction. Our understanding of the geometry and composition of subducted slabs, as well as the physical process of subduction, comes from indirect observation including earthquake seismology, gravity, topography, geochemistry, and petrology of island

17 STUDY FIELDS – DEFINITIONS Geology- It is the study of the Earth, which materials compose it, and how they work together, their processes (earthquakes, floods, erosion) and changes that they have gone through (mountains emerging, valleys, etc.). It also studies the organisms that had been on earth (fossils). It is a wide subject that can be subdivided into fields such as minerology, petrology and so on. Mineralogy- An important part of Geology is the study of Minerals, their physical properties
