Convergent validity

There are two different groups of participants in the study who were chosen for the study arbitrarily. The goal of the study was to find the best way to help students learn better. The researcher chose to use quizzes that were given on a weekly basis. Since the quizzes are only a very small part of the students ' final grade, it is more logical to conclude that the investigator would use the exams that were given to the students as a better measure of student learning than their marks on the…

Damages were not nearly as serious as it would be today, mostly because Southern California was sparsely populated. The effects of the earthquake were quite dramatic, even frightening. Were the Fort Tejon shock to happen today, the damage would easily run into billions of dollars, and the loss of life would be substantial. On March 10, 1933, a 6.4 earthquake hit the Newport-Inglewood Fault, causing serious damage in long Beach and other communities. The earthquake resulted in 120 deaths and more…

Also we will discuss if earthquakes are common in this region. The plate boundary that was associated with the 20 Oct 14 San Gabriel Ecuador earthquake was the Nazac plate (oceanic tectonic plate) and the South American plate forming a convergent boundary (USGS, 2014). This plate boundary can be very active, but since 1900 till 2012 there have been only approximately 50 earthquakes of 5.5 or greater in Ecuador and only two to three near San Gabriel or this time period (USGS,…

The purpose of this paper is the explain a natural phenomena, Axial Seamount. Even if the reader has no knowledge of Axial Seamount, they will be able to fully understand the content of this paper. They will learn facts about Axial Seamount such as what it is, on what plates it is located on, what landforms are around it, etc. Axial Seamount is an underwater volcano located in the Northeastern Pacific Ocean, about 483 kilometers (300 miles) off the coast of Oregon. Because its frequent volcanic…

The theory that today's continents were once part of a more complex and large super-continent, also referred to as “Pangaea”, was first introduced by Alfred Wegener. Wegener, the German meteorologist and geophysicist, formally initiated the detailed hypothesis that the once intact, large, continent had slowly drifted to their present positions. Although others brought fourth evidence, plate tectonics processes and continental drift was not of interest until the late 1950s, when scientists…

In 1912, German meteorologist Alfred Wegener proposed the theory that all the continents were once all one continent and then later drifted apart and separated leading to the seven continents we have today. He thought that 200 million years ago there was one large continent that he called Pangea, which means “All-Earth.” During the Jurassic period the continents were believed to break up into two smaller continents which were called Gondwanaland and Laurasia. The continents were breaking into…

The topic of this discussion is to explain why Africa and South America are moving apart. The drifting apart of Africa and South America has to do with the theory known as the theory of plate tectonics. Based on this model, the crust the coolest part of the mantle, make up Earth’s strong outer layer, known as the lithosphere. Right beneath the lithosphere is the asthenosphere, the hottest part of the mantle. Rocks at this depth are very near the melting temperature, and respond to forces by…

Plate tectonics is a theory about how the plates are constantly moving on top of a layer of magma that is constantly taking in old crust to recycle it this constant movement causes earthquakes, tsunamis and other geological events. The movement of the Pacific and North American plates cause the old sea floor to be replaced by the now wider North American plate. Also with the movement the continental plate was stretched as the Pacific plate pulled the continental plate to the northwest which…

VMS deposits occur in a diversity of shapes ranging from flat lens shaped to large sheet-like sulphide mineral rich bodies (Allen, et al., 2002). The preferred environment for these deposits to form in is submarine near a seafloor opening i.e. black smokers, where hydrothermal fluids escape and precipitate on the ocean bottom (Evans & Moon, 2006). The mineralogy of Kidd Creek VMS deposits often consists out of more than 60 different ore minerals and ore-related gangue minerals, of which 90% or…

The Caribbean tectonic plate has a wide variety of height and depth within its borders. While all the land and islands are quite tall, the middle of the plate, that is mostly sea, is much more deep in some areas than others. Around the Yucatan Peninsula, Central America, and all the islands are gradual slopes that gain more depth the further from land-above-sea-level you get, however, from Honduras and Nicaragua to Jamaica, where there should be deeper sea, there is quite a lot of height but…
