Tectonics

Throughout time, many ideas have come and gone about the movement of continents, some saying that it’s true, and some saying that it’s not. One theory, though, is the most well known and the one most people believe to be true. This is the continental drift theory, created by Alfred Wegener, a German meteorologist. Alfred Lothar Wegener was born on November 1st, 1880 to a German family. He was the youngest child of Richard and Anna Wegener. He had 2 siblings, a sister named Tony Wegener, and a…

SAFS is 700 feet long. The SAFS is 4-10 miles deep, depending on where at along the fault line . (I searched about 10 or more pages for the width but could not come up with an answer, I’m just a terrible researcher). E) What specific type of plate tectonic setting does the SAFS represent? The SAFS is a Transform plate boundary and the two plates are the North American and Pacific. And because it is a Transform boundary it means that the North American and Pacific plates move horizontally not…

granite formations and glacier-carved landscapes that attract everyone from artists to geologists (Huber, 1987). Yosemite Valley was formed by a series of different forces including volcanism beneath the Earth’s surface, the movements of plate tectonics, weathering and erosion, and glaciation that carved the topography. Description of Yosemite Valley: Yosemite Valley measures seven miles long by one mile wide and the valley…

It is important to acknowledge that without the critical state, interesting phenomena cannot occur. The non-critical state is at equilibrium, where Gibb’s free energy is equal to zero, and there are no avalanches. Therefore, the critical state is not at equilibrium, this is only an illusion society sees as a result of the nature of self-organized critical systems. During the intermittent periods between avalanches, society cannot detect any changes, so it is assumed that nothing is happening,…

In 1965, the serpentine rock became California’s state rock; they are abundant in central and northern California. The serpentine rock is a metamorphic rock that forms by the hydration of rocks from the Earth’s mantle; these types of rocks will rise towards the Earth’s surface along fault zones. It can be found in various colors from dark green and brown, to blue with a glossy surface. However, these rocks tend to be slippery and creates a high risk for land slides. Through a series of…

future. I look at the Figure V1 that shows the location, age, and composition of volcanoes and volcanic rocks in New Mexico. Figure V2 shows the histogram of ages for volcanic rocks in the Jemez Mountains. Figure E1 shows the important large-scale tectonic features. After looking at Figure VI and V2 i noticed there is relationship between varies Volcano locations in the state of New Mexico. All the latest (<5Ma) volcano activities have happened in the Jemez Lineament and in Rio Grande Rift.…

prospect is characterized by recent summit felsic lava, caldera collapse, extrusions in the caldera bottom and widespread fumarolic activity, signifying thereby the existence of a shallow magma chamber (Tekelemariam and Beyene, 2005). Active tensional tectonics form fissures up to 2m near the volcanic complex. From the area ground water discharge to the system is guaranteed by the proximity of the area to the western escarpment. The outcome of an integrated interpretation of previous data…

because it contains valuable resources such as hydrocarbons, mineral deposits and groundwater, as well as human hazards, such as earthquakes (Baldridge, 1989). For us to understand geological formation of the rift we must look at the history of the tectonic activity of the Rocky Mountains. Background Leading up to the origin of the Rio Grande rift started during the Cretaceous period, approximately 140 million years ago…

1) Describe the two technological advances that have made it possible to better understand the dynamics of the Earth 's mantle. Two technological advances that have made it possible for scientists to better understand the dynamics of the Earth’s mantle are seismic snapshots and computer modeling. Seismic snapshots enable scientists to determine the temperature and density of the mantle. When an earthquake occurs vibrations are put into motion which create waves that can be detected by…

from a series of volcanoes that cool to make new crust. Crust closer to the rift is newer than the crust farther from the rift. The splitting of the African and South American Plate makes a divergent boundary. A Divergent Boundary is made when two tectonic plates move away from each other. The Mid-Atlantic Ridge is moving 2.5 cm in separation every year. The ridge is one of the longest volcanic chains. Although very few people have managed to see it. The beautiful event of a volcanic eruption…
